THE MAITLAND COLLIERY
As stated in the previous article, there are at the present time eighteen new collieries being opened out in the Northern district, and having already reviewed those in actual work, the larger ones in course of being developed will now be dealt with. It is interesting to note at this juncture that in spite of the depression which at present exists in the coal trade, the measures of this district still continue to attract capital. At no time in the history of our coal-mining have there been so many collieries opening out together, or so much money spent in developing the various estates at present. When those now in course of sinking are in full swing the capable output of the district will be over three million tons a year, or an increase of nearly 40 per cent, upon the present quantity raised. Besides this, boring is going on in all parts of the country, and the discovery of seams is almost a weekly occurrence.
The existence of the Greta coal measures was proved some two years ago close to the town of West Maitland, and no sooner was it found that numerous companies were floated to take up land. The late Mr. W.B. Bradley and Mr. G.O. Hyde secured 537 acres of land half a mile from West Maitland, of which 162 acres is freehold, and the remainder under a mineral lease. Here they determined to establish a large colliery, having proved the existence of the seam, they commenced about nine months ago at a point within two chains of the Great Northern Railway, exactly 20 miles 4 chains from the port of Newcastle. The Greta seam outcrops from the small hills, or downs, round the property, but the firm decided to sink to the dip in preference to tunnelling, so as to catch the coal on the rise, and lessen the cost and labour of underground haulage. The shaft is 14ft in diameter, and is bricked for a depth of 60ft, when hard grey post rock and conglomerate was struck. This continues for a depth of nearly 240ft, the shaft at present being down 300ft. Coal is likely to be struck at any minute, and sinking operations are going on night and day.
With a view of commencing to win coal as soon as the seam is found, the firm have erected a large and complete plant round the mouth of the shaft, which will be capable of dealing with 900 or 1000 tons of coal per diem. The main colliery building is constructed of ironbark, the landing stage or platform being 120ft long by 80ft wide; the whole being very substantial and extensive. A complete winding plant, consisting of a 20 horse-power engine, supplied with steam from two steel shell boilers, is placed in a brick building close to the colliery shed, and is in readiness for work at any moment. Arrangements are being made for another engine to be placed near the first, and the shaft will be fitted with double cages of the latest pattern. Offices and storerooms, and a small coal hopper to hold 450 tons, have been erected, and it is safe to predict that within three months the mine will be at work.
The mine is approached from the Government railway by double loop lines entering on the west side of the main shaft, and connecting again with the railway on the east. The screens which number three, are already in position, while a large number of hopper waggons are being constructed. Owing to the excellent site of the colliery, which is on an eminence overlooking the valley of the Hunter, there has been a large demand for land in the vicinity. The firm has laid off a township 80 acres in extent on the other side of the railway, and erected twenty houses. The township is called Homeville, and the building lots here are already increasing in value. When the mine is in full swing the firm intends erecting a great many more houses upon the same excellent plan as those now on the ground, so that their miners will be able to secure dwellings at equitable rents.
The seam existing under the land as proved in bores and a small shaft is the same as that worked at the famous Greta Colliery, the only difference being that it is even thicker. At the bottom of a trial shaft sunk within a quarter of a mile of the colliery the seam was found to be 21ft, seven feet of it being a very rich cannel coal. This latter mineral is a most valuable deposit, one ton of it giving 12000 cubic feet of gas, or over a fourth more that can be obtained from the best bituminous article. Some idea of the value of such a seam may be gleaned from the fact that the Greta Company found a small seam under three feet and worked it out. The value of true cannel coal, which up to the present has not been found in any large quantities in the district, is £1 per ton, while the hewing price is the same as for common coal. Should this seven feet obtain under the whole estate, and there is very little reason for doubting it, its value will be enormous, and in consequence the opening the seam is causing no little interest.
An analysis of the cannel coal gives the following result:- Moisture, 2.27 per cent; volatile hydro-carbons, 35.39; fixed carbon, 53.91; ash, 8.43; the specific gravity being 1.35. The other coal in the Greta series is very hard, minutely laminated, and is streaky rather than uniform in appearance. Its great hardness makes it very suitable for shipping, and for gas purposes it has no equal in Australia. The average specific gravity is 1.275, and the average composition of the coal taken at different parts of the area is about as follows:- Moisture, 2 per cent; volatile hydro-carbons, 41; fixed carbon, 51.20; ash, 4.60; sulphur, 1.20.
