Bell pits often flooded due to a lack of a drainage system. This, together with the lack of support and the likelihood of collapse, meant they had a limited lifespan. The remains of bell pits can be identified by depressions left when they collapsed. In some places, they will follow a straight line

Typically, no supports were used, and mining continued outwards until the cavity became too dangerous or collapsed at which point another mine was started, often in close proximity. This type of mine was in use in prehistoric times, the Middle Ages, and a few continued in use until the early 20th

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. The bottom of the shaft is enlarged and a sloping roof is created as the desired mineral and surrounding rock is removed – giving its name

as the seam of mineral is being followed. Bell pits were not an efficient way of extracting minerals as they only partially exploited the resources.
