Abstract:

Based on the engineering geological and mining conditions of Wangershan gold mine,numerical simulation method was applied in the study of mining-induced subsidence.By comparing the calculated results getting from the computational model,the regularities of the disturbed stress and displacement fields of rock body were put forward.Moreover,the features of ground subsidence and abrupt collapse were analyzed.Finally,it suggested that filling the mining goaf is a necessary measure in future mining.

Key words: Numerical simulation, Subsidence, Stress field, Displacement field, Wangershan gold mine
