Mechanical model and numerical simulation of the formation of karst collapse columns in the Huainan coalfield of Northern China
Karst collapse columns (KCCs) are channels where groundwater and gas gather, and they pose a great threat to mining safety. In this study, a mechanical model and criterion for the roof collapse of KCCs were established, and simulations were performed to analyze the formation mechanism of KCCs in the...
