There was employed at one time during the sinking of the shafts, the following pumping-plant :— Three engines each with two cylinders, 48, 44, and 26 inches respectively in diameter. There were two sets of pumps 30 inches in diameter by 6 feet stroke; and three sets 20 inches in diameter by 5 feet stroke. The largest quantity of water pumped was 12,000 gallons per minute, and this is the greatest quantity of water pumped at any winning in the North of England. Ultimately the volume of water became so great that the sinking was stopped.

The Kind-Chaudron system of sinking was then commenced, two pits were eventually sunk through the water-bearing strata, and the water was tubbed off by this process.

There are two winding-engines, each having two cylinders, 48 inches in diameter by 6 feet stroke. The winding-engines are capable of drawing about 4,000 tons of coal per day.

On the surface, there are two hauling-engines, each having two cylinders 24 inches in diameter by 4 feet stroke, and fitted with two drums working on the main-and-tail rope system (one is now temporarily used for winding). There is another engine, with two cylinders 20 inches in diameter, driving an endless-rope haulage. There are 18 small hauling-engines in the mine, driven by compressed air, and working secondary-haulage systems.

For the purpose of working the secondary hauling and pumping-engines underground, there are two air-compressing plants: one with two steam-cylinders, 80 inches in diameter, and air-cylinders 80 inches in diameter by 5 feet stroke ; while the other has two steam-cylinders, 40 inches in diameter, and two air-cylinders, 88 inches in diameter by 6 feet stroke.

The colliery is ventilated by means of a Walker fan, 24 feet in diameter and 8 feet wide, driven by a compound horizontal engine, with cylinders 22 and 88 inches in diameter by 4 feet stroke. With the engine running at 41 revolutions per minute, and the fan at 91 revolutions per minute, 256,000 cubic feet of air are produced at a water-gauge of 8 inches. The useful effect is 70.57 and 58.7 per cent, respectively on the water-gauges taken at the fan-inlet or at the surface.

There are 15 double-fined Lancashire boilers, 2 marine type of boilers, and 5 cylindrical boilers.

There are four main jigging-screens, each capable of making four descriptions of coal (best, nuts, peas and duff). There is also a nut-coal jigging-screen. There are six main steel-belts, each about 70 feet long by 5¼ feet wide ; one cross-belt for splint-coal, two cross-belts for small-coal, and two cross-belts for nut-coal.

Lamp-rooms are being erected for oiling, cleaning, examining, repairing and storing upwards of 2,500 safety-lamps.

The whole of the surface-erections and buildings are lighted by electricity, the plant consisting of :— A Robey engine with a cylinder 19½ inches in diameter by 40 inches stroke, fitted with automatic expansion-gear, and working at 80 revolutions per minute. The No. 1 dynamo will supply 400 lights, and the No. 2 dynamo will supply 1,000 lights. It is proposed to carry cables down the shaft and light the shaft-bottoms, sidings, stables, etc.
