This was taken from "The Mining Engineer" book pg 43 onwards.
Clifton Colliery 1890.
Shafts two, 14ft and 13ft diameter 256 yards deep, sunk and working the Deep Hard seam at 4ft 6ins thick. Also working the Deep Soft seam at 3ft 6ins thick at 242 yards deep in the shafts.
About 300 yards south of the shafts the seams downthrow 95 yards and coal being raised that height in addition to depth of shafts.
7 Lancashire boilers 30ft by 7ft feed water supplied by 2 exaust steam injectors at a temperature of 204F.
Winding Engines.
No1 shaft downcast, high pressure horizontal 2cylinders 30inch diam, 5ft stroke, drum 15ft diam, single deck cage carrying 2 12cwt tubs.
No2 shaft upcast, high pressure horizontal engine, 2cyls 26ins diam, 5 ft stroke 12ft diam drum single deck cage, 2 tubs 12cwt each.
Electric shaft signalling.
Ventilation.
40ft Guilbal fan, 12ft wide taking air both sides driven by, compound and condensing engines, high pressure cyl 18ins diam, low pressure cyl 33ins diam, 2ft 6ins stroke.
Fan drifts below level of River Trent and lined with cast iron tubbings..
Note, at time of closure in 1968, the No1 shaft was using a double deck cage, same engines were in use and headstocks were steel construction, in 1890 they were wooden.
Tubs were used throughout the pits life to transport coal, but from the time I was working there all coal was conveyed underground by belt conveyors to pit bottom where it was loaded in tubs before being hoisted to the surface in No1 shaft on twin decked cages.
