摘要
根据望儿山金矿区浅部回采的工程地质与采矿条件,采用数值模拟手段对开采引起的地表沉陷灾害进行了研究。通过模型计算,总结出开采过程中岩体应力场和位移场的变化规律,同时,对地表沉陷特点及突发塌陷进行了预测分析,指出对采空区充填是未来开采避免地面塌陷灾害的必要措施。
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.
