The Scottish Australian Mining Company, better known in the district under the name of Lambton, was formed in London in the year 1860 for the purpose of acquiring mineral property in the Australian colonies. The capital of this most important company is £160,000 shares of £1 each, with power at any time to increased the amount. At that time, the Lambton Estate was in the hands of Messrs Morehead and Young, very shortly after its registration, the company took over the land. It consists of 1860 acres, and extends from the southern boundary of the township of Lambton to the Waratah Company's land, a distance of nearly three miles. The Newcastle Wallsend Estate adjoins the western boundary, while the Commonage and the New Lambton Estate form the greater part of the eastern boundary: its undulating character and splendid situation must at no distant date make the surface extremely valuable for suburban residences. The company also possess a copper mine at Cadia, close to Orange, but some time ago they decided to cease the operations. Since the company's formation it has paid dividends of from 7 to 15 per cent, and the shares at the present time are at a high premium.
In 1861 Mr Thomas Croudace, the present colliery manager and engineer, arrived from England, and commenced the work of opening the mine. The site chosen was at the north east end of the estate, and it was intended to tunnel into the seam which outcrops along the hills to the north of Lambton. For some months, however, the coal was obtained from a shaft, and in 1863 the output was 3361 tons. A tunnel, which has long since been abandoned, but is still used as a travelling road, was then driven into the hill in a westerly direction, and the output from this for some years was sufficient to meet the trade of the company. The colliery from that time shows a rapid development, the annual output for the five years ending 1870 averaging nearly 160,000 tons, while for year 1867 182,007 tons were won, a record which up to that date had not been equalled by any colliery in Australasia. Some years ago the company obtained the right from the Government to mine the coal from 280 acres of the Commonage, and for that purpose drove a second tunnel to the east. When this grant was worked out in 1884, steps were taken to drive a second and larger tunnel into the estate close to the first one, and it is from this drive that the company now draw their coal.
This tunnel enters the hill at a gradual incline for nearly three-quarters of a mile, where four main banks or headings branch off at intervals to the south for various distances, the longest being about half a mile. Another main heading goes nearly due west, and off this the north-western portion of the estate is being worked. These main-ways are beyond doubt the strongest and most secure of any colliery under inspection in the Northern district. Running the entire length of each and all of them are pillars going from 20 to 30 yards in thickness, thus forming a solid barrier, only broken at long intervals by an entrance to a crosscut or working heading. Besides this the return airways and main headings are strongly timbered, so that no fall or crush can possibly extend over them. This is a precaution which needs no comment, and one which it is to be hoped will be followed in the new collieries about to be opened in the district. Pillars have been worked from immense portions of the Lambton mine, and although some of the falls have been extensive, yet no instance of those mainways being damaged in the slightest degree is on record. Off these main engine planes the coal is worked on the usual principle, with the exception that every bord is well "spragged", props being put in by the miner every two or three feet. In consequence of this rule accidents have been rare in the colliery, the manager priding himself, and justly too, on that fact.
The underground haulage obtaining in this mine is most complete, being accomplished by what is known as the "main rope system", the empties finding their way to the various flats or banks by gravitation. The main hauling or winding engine is placed at the mouth of the tunnel, and has control over the main drive; a distance of over half a mile. It is on the horizontal principle, geared three to one, and equal to 50 horse power. A little over half a mile to the east are two other hauling engines placed at the surface of shafts, which go down to the end of the first bank or flat where the other engine-rope stops. The first of these is 20 horse power, and the second 60, and their wire ropes run down the shafts along the southern main headings to the end. A fourth engine of 60 horse power is at the mouth of a shaft further eastward again, and this one does the hauling for the remaining workings. The total hauling distance is about a mile and three quarters, but it will shortly be increased to over two miles. To better explain this system, we will suppose a train of 30 full skips have been put together by the horses at the end of No 5 or at the most easterly engine plane.It is then some 3000 yards from the mouth of the tunnel. One of the wheelers, having fixed the wire rope to the foremost skip of the set, reaches above his head and gives the signal, and in a few seconds the train moves up the heading. On arrival at the end the rope is taken off, and the rope controlled by the main engine takes its place, and quickly drags the set up the half-mile tunnel on to the screening floor. When empty they are sent off, and by gravitation reach the end where they started from their speed being of course regulated by the rope. The same thing takes place in other main-ways, and so full and empty trains are constantly ascending and descending the mine. In case the strong wire rope, which runs on steel rollers placed every eight yards,
