Mine shaft collapse in St Ives, Cornwall

Mining Searches UKs senior geologist Brian Poole gives his insight into a recent shaft collapse in Garth an Creet, St Ives in Cornwall.

The collapse is consistent with a recorded mine shaft named Cornish Shaft, which is associated with a disused St Ives Consols mine. The workings of the mine are recorded to be at least 180 metres deep.

This collapse is one of a number being investigated by Mining Searches UK over the past month alone, with mine workings across the region opening up due to the changes in the weather. We believe that this particular collapse may be in part due to the expansion and contraction of fill within the mine workings, and lubrication within the fill resulting in ground movement.
