摘　　要：介绍了近地表采矿使采空区周围应力平衡遭到破坏,从而引起采空区对应地表发生沉陷的工程地质现象及其产生的危害后果。针对东同矿业公司7#矿体的具体工程地质情况,结合具体采矿方法,利用离散元软件UDEC对由于采矿引起的地表塌陷进行了数值模拟,并对结果进行了系统地分析和比较,可为同类地质条件矿体采矿方法的优化选择和采矿引起的地表沉陷预测提供参考。The paper introduces the engineering geology phenomena of surface subsidence and its damages,caused by near surface mining leading to the unbalance of goal ambient stress. Aiming at the specific engineering geo- logical conditions of 7# orebody in Dongtong Mining Company, the discrete element method software of UDEC is used to simulate the surface subsidence caused by mining activity. The results are analyzed and compared systematically. The research can provide references for the mining method optimization and surface subsidence prediction caused by mining activity with similar geological conditions.
