Bell pit

Depression, a collapsed bell pit, evidence of early coal mining in Middleton Woods

A bell pit is a primitive method of mining coal, iron ore or other minerals where the coal or ore lies near the surface. A shaft is sunk to reach the mineral which is excavated by miners, transported to the surface by a winch, and removed by means of a bucket, much like a well. It gets its name because the pit in cross section resembles a bell.
