[Copyright.'^ SYDNEY: WILLIAM APPLEGATE GULLICK, GOVERNMENT PRINTEH. 1913. t4701-« [M.] A^Ut-jTS' PREFACE, This little work is really a second edition of the article on Coal published in " The Mineral Resources of New South Wales, 1901." In view of the length of time which has elapsed since the publication referred to, and the consequent developments which have taken place in New South Wales Coal Mines, and especially in the Maitland-Cessnock field, it seems advisable that newer records of the composition of our coals should be made public. Within the last three months no less than 194 representative samples of coal have been carefully taken by the Inspectors of Coal Mines, and these have been analysed by the Chemical Staff of the Geological Survey Laboratory. It is hoped that the results, which have been hereto appended, may be of some use to the mining community. EDWARD F. PITTMAN, Government Geologist. Department of Mines, Sydney, ist December, 1911. 2 In a second edition of the same book, published in 1802, the following statements occur (page 45) : — '■ August, 1797. — Mr. Clark, supercargo of the ship Sydney Qove, having mentioned that, two days before he had been met by the people in the fishing boat, he had fallen in with a great quantity of coal, with which he and his companions made a large fire, and had'slept by it duiing the night, a whaleboat was sent off to the southward with Mr. Bass, the surgeon of the Reliance, to discover where an article so valuable was to be met with. He proceeded about 7 leagues t > the southward of Point Solander, where he found, in the face of a steep cliff,' washed by the sea, a stratum of coal, in breadth about 6 feet, and extending 8 or 9 miles to the southwards. Upon the summit of the high land, and lying on the surface, he observed many patches of coal, fr.im some of which it must have been that Mr. Clark was so conveniently supplied with fuel By the specimens of the coal which were brought in by Mr. Bass, the quality appeared to be good, but from its almost inaccessible situation no great advantage could ever be expected from it ; and, indeed, were it even less difficult to be procured, unless some small harbour should be near it, it could not be of much utility to the settlement." Notwithstanding the unfavourable opinions thus expressed, large shipments of excellent steam coal from these seams have, for many years past, been exported, the loading being carried on from jetties. In rough weather, however, there is very little natural protection for shipping on this coast ; and in view of the importance of the southern coal trade, and the extent to which it must grow if better facilities for shipping were provided, the Governuipnt have now constructed, by means of extensive breakwaters, a deep-water harbour at Port Kembla, ■which will enable the largest ocean-going vessels to ship cargoes of coal with safety in the roughest weather. The discovery of coal at the site of the present city of Newcastle is thus referred to by Mr. David Collins at page 47 of the work just quoted : — "September, 1797. — This month began with a very vexatious circumstance. A boat named the Cumberland, the largest and best in the Colony, belonging to the Government, was, on her passage to the Hawkesbu-y, whither she was carrying a few stores, taken possession of by a part of the boat's crew, being at the same time boarded by a small boat from the shore, the ppople in which seized her mnd put off to sea, first landing the coxswain and three ithers, who were unwilling to accompany them, in Pittwater in Broken Bay. Those men proceeded overland to Port Jackson, where they gave the first information of tfiis daring and piratical transaction. Two boats, well manned and armed, were immediately despatched after them, tinder the command of Lieutenant Shortland, of the Reliance. One of these boats returned in a few days without having seen any of them, but Lieutenant Shortland proceeded with the other, a whaleboat, as far as Port Stephens, where he thought it probable they might have taken shelter ; but on the 19th, having been absent thirteen days, he returned without discovering the smallest trace of them or the buat. His pursuit, however, had not been without its advantage, for on his return he entered a river, which he named the Hunter River, about 10 leagues to the southward of Port Stephens, into which he carried 3 fathoms water in the slioalest part of its entrance, tinding Jeep water and good anchorage within. The entrance of this liver was but narrow, and c iveri-d by a high rocky island lying right off it, so as to leave a good passage round the north end of the island, between that and the shore. A reef connects i he south part of the island with th,; south shore of the entrance of ihe river. In this harbour was found a very considerable quantity of coal of a very good sort, anrl lying so near the watei'side as to be conveniently shipped, which gave it, in this particular, a manifest advantage over that discovered to the southward. Some specimens of this coal were brought up in the boat." The two localities where coal was firht discovered in Australia, viz., the cuast near Wollongong and the mouth of the Hunter River at Newcastle, still remain the principal sites of coal-mining activity ^fter a lapse of 11-1 years. It is true that several of the collieries in the immediate vicinity of Newcastle liave been worked out, and that others are within measurable distance (if depletion. Nevertheless, the discovery, within comparatively recent years, of the rich seams of the Greta Measures between Maitland and Cessnock has resulted in the opening up of a number of new collieries which will supply the Australian and foreign markets with first-class coal for very many yfars to come, and NewcastL-s will certainly remain the pore of its shipment. GEOLOGY OF THE COAL-BEARING ROCKS, The geology of the coal-bearing rocks of New South Wales was first studied hy the late Rev. W. B, Clarke, M.A., P.R.S , who deter- mined tlieir age, and, tn a considerable extent, their distribution. His work in this direction was afterwards supplemented by Messrs. Stutch- bury, AV. Keene, C. S. Wilkinson, John Mackenzie, E. Etheridge, Professor David, J. E. Carne, J. B. Jaquet, L. F. Harper, and others. Piofessor David has made a survey of the Newcastle and Maitland Coal-fields, and has shown by geological sections the relations of the Coal Measures of the Northern Fields to those of the Southern and Western Coal-fields. He also discovered the extension of the Greta seams between West Maitland and Cessnock, the district which has since become the greate.it coal-mining centre in Australia. As a result of the investigations of the abovementioned workers, the <;oal-bearing rocks of New South Wales may be geologically classified as follows : — Maximum Geolojfical Aje. thickness j of strata. Locality. Characttr of Coal. I.— Tertiary, Eocene to PUn- About 100 i-ene. feet. Kiandra, Gulg-ong;, Brown-coal or lig:nite. Chouta Bay, &c. II.— -Mksozoic, TnasHic, or About2,500 Trias-Jara. feet. Clarence and Richmond Rivers. Coal suitable for local use only. III.— Pal^izoic, Permo-Car- bnivferoiis. About 13,000 ft. Not til em, Southern, and Western Coal- fields. Good coal, suitable for ^as- making, and for house- hold and steam-raising purposes. IV.— Paueozoic, '"arhnniferox:^ About 10,000 ft. Stroud, Bullah Delah. Very inferior coal, with bands ; of no vwlue. I. — Tertiary. Deposits of lignite or brown-coal, of limited extent, have been found n deep alluvial leads, overlaid by basalt, in many of our gold-fields, as at Kiandra, Gulgong, Forest Reefs near Millthorpe, Thin, unimportant seams. 5.) 6. Upper Irondale seam from 5 to 8 feet thick. 7. The Lithgow seam about 1 1 feet 6 inches thick ; (lower 6 feet worked). 10 The top or Katoomba seam has been worked to a small extent at Hartley Vale, Main Camp, and Katoomba. The sixth seam has been opened in the upper tunnel at Irondale Colliei-y, in Wallace's Black Diamond Colliery (?). at Blackman's Flat, and at Cullen Bullen. All the collieries in the immediate neighbourhood of Lithgow are working the lowest or Lithgow seam. Western coal is essentially steam coal but of an inferior quality to Southern coal ; moreover, it contains a distinctly higher percentage of ash than the latter. A feature of the Western and Southern Goal-fields is the occurrence, in the Upper Coal Measures, of lenticular patches or deposits of kerosene shale, a variety of torbanite, cannel coal, or boghead mineral. It is used extensively for the manufacture of kerosene oil, and also for the pro- duction of gas. The lenticular patches vary considerably in extent ; their thickness ranges from an inch or two up to 4 feet 6 inches, while in length or width they seldom exceed a mile. At the eda;e of the deposits the shale is found to pass into either bituminous or splint coal, or into earthy or stony carbonaceous shale. It is also frequently associated with coal seams either above or below it. Very rich deposits of kerosene shale occurred at Hartley Vale, near Mount Victoria, and at Joadja, near Mittagong, but both these deposits have been worked out. An extensive deposit is at present being worked by the Common- wealth Oil Corporation, at Newnes. The Corporation's leases cover a large area of ground, including the valleys of the Capartee and Wolgan Rivers, and kerosene shale outcrops in buth these valleys, and possibly may underlie the greater part of the intervening tableland ; the charac:er of the shale, however, diflers in the two outcrops, and hence the continuity of the deposit is open to doubt. The shale driven upon from the Capertee Valley is of decidedly better quality than that in the WolgaA Valley, and while the former attains a thickness! of 4 feet 5 inches the latter has a mxximum of about 2 feet. Deposits of kerosene shale, though mucn less extensive, have also been found in both the Upper and Greta Coal Measures of the Northern Coal-field. 2. The Dempsey Series. Underlying the Newcastle Coal Measures, and separating them from the Middle or East Maitland Coal Measures, is a series of barren fresh- water strata known as the Dempsey Series. They have a maximum thickness of 2,200 feet and consist of mudatones, shales, and occasional thin beds of sandstone and conglomerate. Very thin layers of coal are also known to occur, but nothing approaching a workable seam has been found, although a deep bore (nearly 3,000 feet) was put down by the Australian Agricultural Company near their sea pit at Newcastle, and must have completely intersected these Meas?ures. 11 3. The Middle or Tom'igo Coal Measures. The Mifldle, or Tomago, or East Maitland Coal Measures outcrop in the neighbourhood of East Maitland, and their general dip is towards Newcastle and under the Dempsey freshwater series and Upper Coal Measures. The following are the principal coal seams of the Middle Coal Measures, in descending order : — 1 . Top seam, or Donaldson's seam ... 4 to 6 feet thick. 2. Big Ben, or Tomago thick seam ... 7 to 10 „ 3. Tomago thin seam ... ... ... 2-^ to 3 ,, 4. Scotch Derry seam ... ... ... 9 to 10^ „ 5. Rathluba seam ... ... ... .5^ to 11 „ 6. Morpeth seam ... ... ... 4J to 8 It has been estimated by Professor David that the aggregate thickness of the coal in these Measures is about 40 feet, and the total thickness of coal actually worked is about 18 feet. The Middle Coal Measures do not occur in the Western (Lithgow) Coal-field, where tke Upper Coal Measures rest on the Upper Marine beds. In the Southern (Illawarra) coal-field, also, their occurrence has not actually been proved, though a bore which was put down at Bulli in 1893 showed a greater thickness of freshwater beds than might normally be expected in the Upper Coal Measures, and near the bottom there were two seams of coal which may possibly belong to the Middle or Tomago Coal Measures, It is evident, however, that these measures (Middle or Tomago) must thin out going southwards, though how far southwards they really extend is a matter of uncertainty at present. None of the diamond-drill borgs put d'^wn near Sydney has bpen carried Heep enough to intcsect any but the uppermost seam of the Upper Coal Measures. Going northwards from Maitlami, also, there is no certain evidence of any outcrop of the Middle Coal Measures, though it is somewhat doubtful whether the Rix's Creek seams, near Singleton, belong to those Measures or to the Newcastle Series. The maximum thickness of the Tomago Measures is belie\ed to be about 1,800 feet. 4. The Upper Marine Series. The Upper Marine Series occurs below the Middle Coal Measures, and above the Lower or Greta Coal Measures. The beds of this Series in the Northern Coal-field have been classified by Professor David as follows, in descending order : — 1. Chsenomya Beds — Cherty shales with great abundii.nce of the fossil lamelli- branch shell Chsenomya. Also contain numerous specimens of glendonite-; (calcareous pseudo- morphs after crystals of j.;lauberite) ... ... 130 feet 12 2. Crinoidal Beds — Soft shales and raudsfcones, characterised by an abundance of crinoid remains. These beds also contain glendonites on several horizons ... ... 1,570 3. Branxton Beds — (a) Muree beds, consisting chiefly of calcareous sand-\ stones (with a great abundance of the small fossil brachiopod Strophalosia) resting upon a hard calcareous conglomerate, known as the Bolwarra conglomerate. This rock shows a bold outcrop, and conseqviently forms a definite geological horizon which is easily identified... 420 feet. (b) Shales, mudstones, and sandstones. Fossil corals / 3,000 feet (Trachijpora) _very abundant in a bed a few hundred feet below the Bolwarra conglomerate. An enormous abundance of Fenestellidce occur in these rocks, which are also distinguished by the presence of numerous large glacial erratics (granite and quartz-porphyry), and occasionally small ice-scratched boulders The Upper Marine beds may be seen underlying the Middle Coal Measures to the south-east of the township of Morpeth, also between West Maitland and Branxton, and about a mile to the north-north-east of Singleton. In the Southern Coal-field the Upper Marine beds are distributed over a fairly wide area. They rise above sea level in the vicinity of WoUon- gong, and continue to reach greater elevations as they are traced south- wards. They consist of a lower or sedimentary stage, and an upper or volcanic stage. They have been classified by Professor David and Messrs. Jaquet and Harper as follows (in descending order) : — Upper or Volcanic Stage — Cambewarra trachyte ... Saddleback dolerite Jamberoo tuffs (with marine fossils) ... Bumbo basalt (a dense rock with large labradorite crystals) ... ... ... ... , ... Kiama tuffs Blow-Hole basalt Westley Park tuffs 1,720 feet 350 feet 60 510 500 )> 120 140 5J J) 40 )) 13 Lower or Sedimentary Stage — Encrinital Beds — Gray tuflfaceous shales, containing Encrinites, Retepora, and abundance of Pei-mo-Carboniferous marine fossils 800 feet Nowra Grits — Gritty grey sandstones containing marine fossils. These beds probably correspond with the Muree beds of the Northern Coal-field ... 250 feet Wandra Wandian Pebbly Sandstones — Dark grey mudstones, more or less gritty in places, with abundance of marine shells ... ... 550 feet Conjola Beds — Pebbly sandstones (with small erratics), and layers, of conglomerate, and ferruginous grits, passing downwards into very fossiliferous sandstones (containing abundance of a species of McBonia), mudstones, and fine-grained sand- stones l,400feet In the Western Coal-field the Upper Marine Series is represented, so far as at present known, by only coarse conglomerates, which are probably the basal beds, and which rest directly on contorted beds of Devonian age. 5. The Lower or Greta Coal Measures. The Greta Coal Measures outcrop as a narrow belt of conglomerates, sandstones, shales, and coal seams. The total thickness of these beds never, apparently, exceeds 300 feet. In the neighbourhood of Maitland their outcrop follows a very irregular course, as they have been thrown into anticlines and subjected to considerable faulting. To the north of Maitland they have been traced, with intervening brtaks, as far as Wingen, and they again occur as an isolated belt to the north of Inverell, and extending thence through Ashford to near the Queensland border. The outcrop of the Greta Measures is shown, on the accompany- ing map of the State by a red line. In their normal position they lie upon the Lower Marine beds, and are overlain by the Upper Marir.e Series, but they have been much intruded by igneous rocks in the nerthern parts of the State, so that it frequently happens that they are bounded on one side by either granite or quartz-felsite, and their angle of dip is often very considerable. 14 Two coal seams occur in these Measures, viz. : — 1. The upper seam, varying from 14 to 32 feet in thickness. 2. The lower seam, varying from 3 to 11 feet in thickness. A few very small lenticular patches of kerosene shale were found to occur in the upper coal seam at Greta, and a seam of cannel, about 5 feet thick, in the same (upper) seam at Homeville, near West Maitland. The coal from the Greta Measures is very hard, and can therefore be very economically worked, inasmuch as it makes a minimum quantijgr of " smalls " ; it is, moreover, of exceedingly good quality, being useful for gas-making and housshold purpo-es, and also for steam-raising, though, on account of its large proportion of volatile hydrocarbons, it has a tendency to burn rather tno fast for use with a foi-ced draught ; moreover it makes too much black smoke for navy purposes. Still it is undoubtedly the purest, and, generally, the most useful coal iu the State, while the great thickness of the seams in which it occurs makes it an exceptionally valuable deposit of fuel. One disadvantage from which the Greta coal suflFers is that it contains rather a high percentage of sulphur, and this is especially true in regard to the top bands of coal in the upper or thick seam These arc termed by the miners the ■' brassy tops," on account of the presence of so much iron-pyrites (maroasite) in them. They are usually left as a roof, and only the lower part of the seam is worked. When the "brassy tops "fall, in the pillar workings, they are very liable to spontaneous combustion, and many gob-fires have been traced to their agency. The Greta coal seams are being very e.Ktensively worked between West Maitland and Cessnock, and it cau safely be stated that this stretch of country, covering a distance of about 15 miles, is at the present time by far the most important coal-mining district in Australasia. The following ten collieries are now at work within this area, viz.. South Greta, East Greta, Heddon Greta, Stanford Merthyr, Pelaw Main, Hebburn, Abermain, Neath, Aberdare, and Aberdare Extended; and their aggregate output for the year 1910 was 2,561,861 tons. The Greta Coal Measures have also been recognised in the Clyde Valley in t'le extreme southern portion of the Illawarra Coal-field; but the seams there, so far as they have been prospected, do not appear to be workable under present conditions, the coal being somewhat inferior and the seams thin. Kerosene shale, of rather inferior qiiality, has also been met with in that neighbourhood. In the Western Coal-field there is no appearance of the Greta Coal MeasuT'Ps. The Upper Coal Measures of that field lie upon the Upper Marine beds, and the latter rest, unconformably, upon Devonian strata. Photo, i Pittman, Twenty-two feet of first-class coal without a band. Greta Coal Seam in the Stanford-Merthyr Colliery, Kurri Kurri, near Maitland. 15 6. The Lower Marine Series. The Lower Marine series in the Northern Coal-field has been described by Professor David as follows, in descending order : — 1. Farley Beds — Hard sandstone with marine shells. A small variety of Martiniopsis is very abundant in the upper part of these beds. At the base of the beds occurs the Ravensfieldsandstone — afine-grained brownish marine sandstone much used for building purposes. It is abundantly fossiliferous, the most character- istic genera being Edjnondia{?') and Goniatites. ...1,000 feet 2. Lochinvar Beds — Amongst the higher beds may be mentioned the tuffa- ceous chloritic sandstones of Harper's Hill, the Eurydesma cordata and Fenestella beds of Annan- dale, and the foraminiferal and the Stenopora limestones of Pokolbin. Then succeed andesitic and basaltic tuffs and agglomerates with int«r- bedded andesites, natrolite basalt, and hyper- sthene basalt. At the base of the beds are small glaciated boulders in a reddish shaly matrix. Gangamopteria has been traced downwards to about the middle of these beds. ... ... ... 3,800 feet. The Lower Marine Series does not occur in either the Southern or the Western Coal-fields, where the Upper Marine beds rest 'directly upon Devonian strata. Continuity of the Gual Measures under Sydney. The general dip of the Permo-Cartioniferous Coal Measures being towards Sydney as a centre it was a fair assumption that they would be foun-1 to be continuous from north to south, and from Lithgow eastwards to the coast. The late Kev. W. B. Clarke was the first to argue this on scientific grounds in the year 1847. In that year he made the following statement in his evidence before a Select Committee of the Legislative Council on Coal Inquiry : — " If Wf: take a dip of only 1 degree from Newcastle to the south, and from lUawari a to the north, the synclinal curve will meet at the entrance to Broken Bay, which is exactly half way (the extremity, probably, of the minor axis), at a depth of 4,680 feet — the depth of the coal seams if continuous." 16 For many years past there had been no doubt in the minds of local geologists as to the Coal Measures of the Newcastle and Illawarra fields being continuous under Sydney, and the only question upon which there was any divergence of opinion was as to the actual depth at which the coal would be found to occur. This question of depth was, however, one of considerable importance from a commercial point of view, since it was quite possible that the depth of the coal under the metropolitan area would be too great to allow of its profitable extraction ; and the Rev. W. B. Clarke's estimate (already alluded to), on the basis of a regular dip of only 1 degree from Newcastle and Illawarra respectively towards the centre of the basin, indicated a depth of 4,680 feet bo the coal under Broken Bay. Obviously, the problem could be most easily solved by boring, and the first attempt in this direction was made in 1878, when a diamond drill bore was put down at Newington, on the Parramatta River. This bore attained a depth of 1,312 feet without striking coal, and was then abandoned. In the following year another bore, put down at Botany, reached a depth of 2,193 feet, when it also was abandoned without accomplishing its object. The third attempt was made at Moore Park, where, at a depth of 1,860 feet, the bore was abandoned without having reached the coal. Other unsuccessful bores were put down at Narrabeen, north of Manly, 1,985 feet ; and at Rose Bay, Sydney Harbour, 1,700 feet; the cause of failure in each case being that a suflficient depth was not attained. In 1884 a bore at Camp Creek, near the site where the Metropolitan Colliery's shafts were subsequently sunk, was successful in striking the Bulli seam, 12 feet thick, at a depth of 846 feet from the surface. In 1886 a bore was put down, near the Waterfall railway station, to a depth of 1,586 feet, and two seams of coal were reached — viz., an upper seam, 4 feet 8^ inches thick, at a depth of 1,513 feet; and a lower seam, 6 feet 1 inch thick, at a depth of 1,577 feet from the surface. In 1887 another successful bore was completed, this time at Dent's Creek, on the Holt-Sutherland Estate. The total depth reached was 2,307 feet from the surface, and two seams of coal were again pene- trated, viz., an upper seam, 4 feet 2 inches thick, at a depth of 2,228 feet, and a lower seam, 5 feet 3 inches thick, at 2,296 feet from the surface. Again, at Moorebank, near Liverpool, a bore was carried to a depth of 2,601 feet, and penetrated three seams of coal. The upper seam, 1 foot 5 inches thick, was met with at 2,493 feet ; the second, 1 foot 4 inches thick at 2,507 feet ; and the lowest, 6 feet 6 inches thick, at 2,583 feet from the surface. The Liverpool bore was situated at a distance of 20 miles south-west of Sydney, while the Holt-Sutherland bore was only about 15 miles in a direction rather west of south from the city ; so that the evidence 17 afforded by them went a long way in support of the theory of the continuity of the Newcastle and lUawarra Coal Measures, though it did not absolutely demonstrate it. The opinion was formed, that the comparatively thin seams met with in the Liverpool and Holt-Sutherland bores were the result of a splitting up of the thick (Bulli) seam penetrated at Camp Creek, and it was believed that these seams would reunite as they were traced further to the north — a belief which was subsequently confirmed. In 1890 a party of gentlemen, who had applied for the right to mine for coal beneath Sydney Harbour, deemed it advisable to place the question (of the occurrence of coal there) beyond all doubt before forming a company to erect the necessary plant, and sink the shafts. They, accordingly, put down a diamond drill bore on Cremorne Point, on the northern shore of the harbour, and in 1891 this bore was completed at a depth of 3,095 feet. At 2,801 feet a seam of coal 7 feet 4 inches thick was penetrated, but, unfortunately, the site had been chosen close to the outcrop of a dolerite dyke, which had intruded the seam just where the drill penetrated it, and, consequently, the coal was found to be charred, or partly converted into coke, by the action of the molten rock. It was then decided not to endeavour to float the company until a sample of good coal from the seam could be exhibited, and it consequently became necessary to put down a second bore. The Government of the day regarded the experiment as one of almost national importance, as the future value to the State of workable seams of coal beneath Sydney could scarcely be overestimated. They therefore acceded to a request for assistance, made by the syndicate, and granted a sum of money from the Prospecting Vote to cover part of the expense of putting down a second bore at Cremorne. The site for the second bore was chosen as far away as possible from the outcrops of dolerite dyke, and boring operations were commenced in July, 1892, under the supervision of Mr. W. H. J. Slee, Superintendent of Diamond Drills. On the 9th November, 1893, the drill penetrated a fine seam of coal, 10 feet 3 inches thick, and free from any alteration by contact with dykes. The depth of the bore from the surface (143 feet above sea level) to the roof of the coal seam was 2,917 feet. The following is a descending section of the seam : — Roof, clay shale. Coaly clay shale Splint coal, somewhat inferior Coal, splint and bituminous, of good quality Band, dark clay shale Coal, splint and bituminous, of good quality Coal, soft, bituminous, a trifle clayey .. 10 Floor, black carbonaceous clay shale, containing irapressions of vertebraria. ft. in. ... 1 ... 8 2 10 '.'.'. i ... 6 4i ... 34 18 Six samples were carefully taken from different portions of the core of coal brought up by the diamond drill, and these were analysed by Mr. J..C. H Mingaye, of the Geological Survey Laboratoiy. The mean of these six analytes gave the average composition of the entire seam as follows : — Hygroscopic moisture '66 Volatile hydrocarbons .. 17'57 Fixed carbon ... ... ... ... ... 71'091 „ , HI ' Ash 10-68 I Coke, i 100-00 Sulphur, "24 ; specific gravity, 1-346 ; calorific value, 13. The result of the horing operations at Cremorne established beyond all doubt the fact that the Newcastle and Illawarra Coal Measures are continuous under Sydney, and an enormous coal-bearing area, in which the coal occurs within a workable depth from the surface, is thus add^d to the already large reserves of the State. There is reason for believing that the Cremorne bore penetrated the basin at or near its deepest part, and that the Bulli seam, which is without doubt the one met with in this bore, will he found to rise gradually as it is traced further north and south, as well as east and west, from Sydney. It is not unreasonable to expect that several, if not all the other seams of the Upper Coal Measures will be found to occur within a workable depth from the surface under Sydney. The question as to whether the Middle or Tomago Coal Measures extend as far south as Port Jackson has not yet been definitely settled, as the Cremorne bore did not descend to a suificient depth to intersect them, if present. There is no reason to doubt that the Lower or Greta Coal Measuies underlie Sydney, but their depth must be so great that there is very little probability of their ever being worktd there. The results obtained in the Cremorne bore led to the formation of the Sydney Harbour Collieries Company. It was originally intended that their shafts should be sunk on the high land at the back of Athol Bay, near Bradley's Head ; but objections were made to this, on the ground that the mining plant would deface the natural beauties of the harbour. Eventually the company purchased some land at Longnose Point, Balmain, for the purpose of sinking shafts and erecting a plant capable of working the coal under the wa'ers of Port Jackson. This site is situated about 3 miles from the bore at Cremorne, and, unfor- tunately, the shafts were sunk thereat great expense without previously lioring to ascertain whether the character of the seam had varied. These shafts were about 2,900 feet deep, circular in form, with a diameter of 18 feet, and lined throughout with brickwork. When the 19 first shaft reached the coal it was found that the seam was split by a band of shale, and could not, at that point, be worked remuneratively. The section was as follows : — ^ ft, in. Coal ■> 9 Shale 2 11 Coal 10 It was then decided to drive east in the direction of Cremome, and after some time it was found that the shale was becoming thinner, and being gradually replaced by coal. The face at present being worked is 66 chains from the shaft, and it shows 5 ft. 5J in. of coal without, a band, the coal being of good quality. The colliery is well equipped with the most modern machinery, including a Walker fan 24 feet in diameter and 8 feet wide, for ventilating the workings. The operations of the company are being watched with great interest, as the colliery is one of the deepest in the world. Unfortunately, insufficient capital was provided in the first instance, and unforeseen expense was entailed in opening up the colliery, on account of the splittiug of the seam. It is believed, however, that most of the difficulties have now been surmounted, and mining should proceed smoothly in future. No trouble has yet been experienced in regard to the occurrence of water or firedamp, although it was feared that the latter might be found troublesome. The question of pressure was also one that, it was anticipated, might cause some trouble, as these coal workings are two and a half times as deep as any previously in existence in Australia So far, however, there has been no difficulty on this score. One of the great advantages possessed by this colliery is that the largest ocean- going steamers are able to load their cargoes of coal from its wharf in the harbour. The accompanying geological sections show the structure of the main coal basin of New South Wales from north to south, and also from east to west ; but it must be stated that the information shown in the deeper parts of the basin is more or less theoretical, except in regard to the uppermost seams of coal and overylying strata where they have been penetrated by bores (as shown in the sections.) The depth of the lower seams under Sydney, for instance, may be much greater or much less than that shown in the sections, for there may be a thickening or a thinning-out of the intervening strata. It has been shown that the Upper, or Newcastle Coal Measures, extend from Newcastle on the north to Ulladulla on the south, and also to Lithgow on the west, and that in the central part of the basin they occur at a depth of some thousands of feet, being overlain by the Hawkesbury series (Triassic). It is not possible, however, to correlate 20 all the seams occurring near Newcastle with those discovered in the Southern and Western Coal-fitlds ; indeed it will be noticed that nearly twice as many seams have been mentioned in the first-named locality as in either of the latter. Doubtless some of the seams thin out altogether between Newcastle and Ulladulla, while others may split and make together again at intervals. It would certainly be very remarkable if all the coal seams followed the same horizons, and main- tained the same approximate thickness for a distance of 200 miles. It is, nevertheless believed that the Wallarah seam of the Northern Coal-field is identical with the uppermost or BuUi seam of the South, and the top or Katoomba seam of the West ; also that it coincides with the seam met with in the diamond drill bore at Sydney, at a depth of nearly 3,000 feet, and which is now being worked in the Sydney Harbour Collieries, Limited. If this be so, the seam has a wonder- fully persistent development ; its quality, however, is by no means uniform. For instance, in the Southern Coal-field the upper or Bulli seam consists of good steam coal, and has been extensively worked. In the Sydney Harbour Colliery the coal is of about equal quality, while in the Newcastle Coal-field the Wallarah seam is only worked in one colliery, and in the Western Coal-field the workings in the top or Katoomba seam have been unimportant. Volcanic Bocks Associated with the Per mo-Carboniferous Coal Measures. In the Southern Coal-field there occurs, between the Upper Marine beds and the Upper Coal Measures, a considerable thickness of volcanic rocks, consisting of sheets of basalt and trachyte, and beds of grey and red volcanic tuffs. These contemporaneous lavas and tuffs represent a maximum thickness of about 1,700 feet near Kiama, where the upper basalt sheet, which has a remarkable prismatic structure, is quarried for road metal. Further to the north, about 4 miles from WoUon- gong, a quarry was opened in the same rock for the purpose of obtaining large blocks wherewith to construct the moles for the deep- water harbour of Port Kembla. v Again, in the Lochinvar beds of the Lower Marine Series of the Northern Coal-field, Professor David describes a series of inter-bedded andesites, natrolite-basalt, hypersthene-basalt, and andesitic and basaltic tuffs and agglomerates. The augite-andesite varies from 500 to 1,000 feet in thickness, and terminates in a bed of augite-andesite tuff. The Greta Coal Measures in the northern part of the State have been intruded by granites and quartz-felsites, which have destroyed a considerable proportion of the coal ; and in all parts of the main coal basin the Upper Coal Measures have been intersected by intrusive dykes, though their effect upon the coal is much more noticeable in some cases than in others. At Bowral, near Mittagong, an intrusive mass of 21 trachyte has converted a seam of coal into typical anthracite ; this trachyte is largely used for building purposes iu Sydney and elsewhere, as it is an extremely durable as well as ornamental stone of a dark- grey colour. In nearly all other instances the dykes which intersect the Coal Measures consist of dolerite or basalt, which is clearly post- Triassic in its age, as it has intersected the Hawkesbury Series as well as the underlying Permo-Carboniferous rocks. The dykes are of various widths, and have frequently been decomposed at the surface into a bulF or greyish-white plastic clay. As a general rule, where a coal seam has been intersected by a dyke, the coal is found to be cindered or coked for a short distance (a foot or so) on each side of- the line of contact, but in some cases a much greater amount of damage has resulted from the intrusion of the volcanic rock. Thus_ the Borehole seam was much cindered in places in the Stockton Mine (now abandoned), Newcastle, and the Lower Tomago seams have suffered considerably from the same cause at Hexham and Ash Island, being converted into natural coke or completely cindered in places. It is in the Southern Coal-field, however, that the greatest effect of volcanic intrusions upon the coal seams is noticeable ; and this fact is, no doubt, due to the greater size of the dykes intersecting the field, and its proximity to the ancient centre of volcanic activity. Near Bulli, dolerite dykes of great width (up to 100 yards in some cases) can be seen at the surface, and the colliery workings have proved that off-shoots from these dykes, in the shape of horizontal sheets, have followed the coal seams for considerable distances, with the result that large areas of coal have been converted into natural coke. In some instances there has been a good sale for this natural coke, at a satis- factory price, for fuel, but on the whole, there can be no doubt that the effect of the volcanic intrusions near Bulli has been very detrimental. I V. — Pal^iEOZoic. — Carboniferous. In the neighbourhood of Stroud, about 40 miles to the north of Newcastle, seams consisting of coal and bands, occur in rocks which correspond in age with the Carboniferous System of Europe. The coal is of very inferior quality, however, and certainly cannot, so far as has been ascertained, be regarded as workable. Moreover, the deposits are probably very limited in extent, so that the true Carboniferous rocks may safely be disregarded as a possible source of fuel in New South Wales. Quantity of Goal available in New South Wales, Attempts to estimate the quantity of coal available in any country are more or less hazardous, owing to the tendency of the seams to vary in thickness, and of the coal to alter in quality. 22 In a comparatively young country like Australia, this statement is even more applicable than in the ease of European coal-fields, for here there has been much less exploration of the seams, and there are, consequently, many more uncertain factors in the calculation. Reference has already been made to the fact that the coal seams of the Upper Coal Measures outcrop at the surface in three widely separated districts, viz., Newcastle, lUawarra, and Lithgow, and )that they dip under the intervening country, and attain their greatest depth probably near Sydney. The only knowledge which we possess of the deposits of coal in their deepest parts has been acquired by boring, in the first instance, and, subsequently, by the sinking of a pair of shafts to the top seam, which was penetrated at a depth of about 2,900 feet in the Sydney Harbours Colliery. It has never been ascertained how many of the other seams of the Upper Coal Measures underlie this seam, whether the Middle Coal Measures occur there or not, at what depth the Greta seams occur, or whether they maintain their quality. As the Greta seams outcrop in both the Northern and Southern Coal-fields, it is probable that they do underlie Sydney, but their dejjth from the surface there is doubtless very great indeed — probably 8,000 or 10,000 feet — so that there is very little chance of their ever being worked. While it is impossible to- correlate with certainty many of the coal-seams of the Northern Coal-fields with those of the Southern and Western Fields, we are in a position to say that the seams which contain the best coal in any one field are of inferior quality or unworkable in the others ; in other words, there is such variation in the quality of the coal that it is impossible to say over what area any particular seam may or may not be worked. In 1907 a diamond drill bore was put down to a depth of 1,141 feet at Bungaree Norah, on the coast near Tuggerah Beach Lake. Several coal seams were intersected, though none of them was of a very satisfactory character. The uppermost, or Wallarah seam, was met with at a depth of 324 feet ; it was only 2 fept thick, and an analysis showed 16'94 per cent, of ash. What was probably the Great Northern seam was intersected at a depth of 401 ft. 6 in., and proved to be 6 ft. 6 in. in thickness, but on being analysed the coal was found to contain 18'35 per cent, of ash. None of the other seams below this was of a workable character, and, unfortunately, the bore was not carried deep enough to test the Borehole seam, which probably occurs here at a depth of not less than 1,600 feet. In the year 1910 a diamond drill bore was carried to a depth of 3,005 feet on the northern side of the Hawkesbury River, near the railway crossing. The top seam (Wallarah, or Bulli) was intersected at 2,322 feet, pnd proved to be 3 ft. 3 in. thick. The coal was of a decidedly friable character, and an analysis showed that it contained 12-25 per cent, of ash. At a depth of 2,360 feet, another seam of coal 23 2 ft. 10 in. thick was met with, and below this there were several other inferior seams, but the boring was stopped before the hoi-izon of the Borehole seam was reached. The results of the two bores just referred to would seem to indicate that the Newcastle seams deteriorate as they are followed south from Lake Macquarie. At the same time, too much reliance must not be piaced upon this evidence, for experience has shown that very great changes may take place, both in the thickness and quality of a coal- seam, within a comparatively short distance. It is clear, therefore, that any estimate of the quantity of coal in New South Wales must be based upon very uncertain data. For the purposes of an approximate estimate, however, we may assume the following : — PaZmozoic Coal-fields. 8q. milei. Area within which the Upper and Middle Coal Measures are productive within 4,000 feet o{ the surface ... ... 15,800 Area within which the Greta Coal Measures are productive in the Northern District, within 4,000 feet of the surface ... 250 Area within which the Greta Coal Measures are productive in the Southern District, within 4,000 feet of the surface . . . 500 Total area 16,550 In their most productive areas the Upper Coal Measures contain about 40 feet of workable coal ; the Middle Coal Measures contain about 18 feet of workable coal ; the Greta Coal Measures contain about 20 feet of workable coal. There is, therefore, a maximum thickness of about 78 feet of workable coal in the Permo-Carboniferous rocks. It would, however, be very un.<(afe, in estimating our coal resources, to assume that anything approaching that thickness of coal is available under the area mentioned above, for reasons which have already been given. It seems preferable, therefore, to base the calculation upon the assumption that a thickness of only 10 feet of workable coal underlies an area of 16,5-50 square miles. Taking 34 lb. as the average weight of a cubic foot of coal, and deducting one-third of the gross weight for loss in working, impurities, ifec, this, would represent a total quantity of 115,346,880,000 tons of available fuel in the Permo-Carboniferous Coal Measures within a di^pth of 4,000 feet. No estimate of the coal obtainable in the Middle and Upper Coal Measures between depths of 4,000 and 6,000 feet can be attempted, because the necessary data are not available, no bore or shaft having ever penetrated deeper than the uppermost seam of the Upper Coal Measures in the deeper parts of the basin. The Greta Coal Measures are of wide extent, but as they are separated from the Upper' and Middle Coal Measures by a thickness of about 6,000 feet of marine beds, and are, therefore concealed for the greater part, the quantity of coal 24 availabk in them between 4,000 and 6,000 below the surface can only be estimated under a limited area which has recently been surveyed by Professor David. Within this area, which is in the vicinity of Kurri Kurri and Cessnock (vide map), they are estimated to contain 1,893,000,000 tons of workable coal above a depth of 4,000 feet, under an area of 158 square miles, and an additional 1,200,000,000 tons between 4,000 and 6,000 feet, under an area of 100 square miles. Analyses of Nevi South Wales Goals. A large number of analyses of so-called " samples " of coal from the Northern, Southern, and Western Coal-fields of New South Wales is on record, and it has been customary in the past to take the mean of these analyses as representing the average composition of the coal from the several fields. There is good reason for believing, however, that these so-called samples were not, in many instances, ti'uly representative of the various seams from which they were selected, many of them being single fragments taken from some particular band in which the coal presented a favourable appearance ; and hence the results obtained probably indicated a better quality of coal than could be obtained in bulk from the seam. The value of an analysis of a sample of coal depends mainly upon the manner in which the sample is taken, since the proportions of volatile hydrocarbons, fixed carbon, and ash, vary considerably in difiierent parts of the same seam, and carelessly selected samples may give an absolutely misleading idea of the value of any seam for commercial purposes. With the object, therefore, of obtaining .as reliable information as possible in regard to the average composition of the coals at present being won in New South Wales, proximate analyses have been made of 194 thoroughly representative samples of coal taken during the past three months from all the collieries now working in the Siiate. In all the larger collieries, at least two sample"? have been taken from working faces as far removed from one another as possible, and in many cases samples have also been taken from portions of the' seams not at present being worked. The samples were taken by the Government Inspectors of Mines in accordance with the following directions : — "Details to be observed in taking samples of coal for analysis : The samples should be taken from two of the working faces of the colliery as far from one another as possible. A strip of coal should be carefully cut out with a pick for the whole thickness of the seam as worked, so that the samples may represent the coal actually sent to market. The strip of coal should be the same width (say, 3 inches) all the way from the roof to the floor, and the depth of the' cut should also be uniform. If any bands occur, which are usually picked out before the coal is sent to maricet, 25 they should also be excluded from the sample, but all those which are usually left in the coal sent to market should also be included in the sample. Before taking a sample the floor of the working place should be cleared, and a large strip of brattice-cloth should be spread out so as to catch all the coal cut out of the strip. The entire quantity should then be broken down carefully to the size of small nuts, and thoroughly mixed. One-half of this should then be again well mixed and halved, and the mixing and halving should be repeated until a sample of about 1| lb. or 2 lb. in weight has been obtained. It is especially desired that the greatest care be observed in attending to all the above details." The analyses have all been made in the Geological Survey Laboratory (by Messrs. J. C. H. Mingaye, H. P. White, and W. A. Greig), and the details of these are appended. The average composition of the coal from the Upper or Newcastle Coal Measures in the Northern Coal-field, as calculated from the analyses of seventy-eight samples, is as follows: — Hygroscopic moisture 2"01 Volatile hydrocarbons 36 '01 Fixed carbon 53 27 Ash 8-71 10000 Sulphur 0468 Calorific value 12'7 The average composition of the coal from the Middle or Tomago'Coal Measures in the Northern Coal-field, as calculated from the analyses of five samples, is as follows : — Hydroscopic moisture 1 'SS Volatile hydrocarbons .. 3571 Fixed carbon 52-77 Ash 9-64 100-00 Sulphur 1-185 Calorific value 12-5 The average composition of the coal from the Lower or Greta Coal Measures in the Northern Coal-field, as calculated from the analyses of fifty-one samples, is as follows : — Hygroscopic moisture ... . . 1 84 Volatile hydrocarbons 41-61 Fixed carbon 49 '52 Ash 7-03 100-00 Sulphur 1-291 Calorific Yalue 13-07 26 The average composition of thirty-one samples of the coal from Greta seams, as actually worked in the Northern Coal-fleld, is as follows : — HygrosGopic moisture ... ... ... ... 189 Volatile hydrocarbons Fixed carbon ( ..
