A karst collapse pillar (KCP) is caused by the karst subsidence that occurs in carbonate rock distribution areas. Current KCP studies focus mainly on aspects such as the cause of formation, rule of development, groundwater inrush, and structural characteristics of the pillar and sidewall rock...

The prediction of groundwater inflow in karst collapse pillar has an important impact on safety underground mining, and the occurrence of these groundwater disasters is likely to be controlled and decreased via establishing an accurate groundwater inflow prediction system. However, the...
