NEHL - A drift mine was located west of Hedley Hill pit village in the 19th century, and is one of the few which last into the 20th century. It was connected by tramway to the row, which radiated either side of the settlement. There was a large waste heap immediately north west of the drift, next to a loop to allow wagons to pass each other into the drift. It was likely connected to the many other mines in the area.
