Simulation on Compound Action between Deep Fault and Karst Collapse Column-Take GuQiao Coal Mine as an Example

摘要：

In deep mining area, karst and fault developed, water inrush characteristic is the result of compound action between fault and karst collapse column, Discontinuous Deformation Analysis software (DDA) was used to simulate the compound action between fault and karst collapse column, The results showed that, on the one hand, the fault slip direction and scope was controlled by the column geometry form, on the other hand, the growth of fault will speed up the formation of collapse column.
