NEHL - Hedley Colliery was situated around a mile west of Hedley-on-the-Hill, and was linked by a road directly from New Ridley. Little is known on the pit apart from that it was owned by William Walker, and that coal was sold locally rather than exported to the wider country.

Advertisements for positions at the mine, namely "good hewers", carried on into the 20th century. A flurry was seen in 1906, though references dry up afterwards. Therefore it can be determined the pit closed soon after.

The pit had a very small internal tramway system between the shaft and what is likely the heap. They will have transported the tubs from inside the drift to the waste. There was also a second shaft located around 200m north east, which had its own tramway leaving the shaft.

The pit heaps are still in situ today.
