摘　　要：以常村煤矿2311工作面为研究对象,通过概率积分法预测和离散元数值模拟,对比分析采取离层注浆充填开采与非注浆条件下开采引起的地表沉陷程度。结果表明:注浆开采后,地表沉降幅度可以得到有效控制,从而有效控制地表沉陷,提高煤矿资源回收率。Taking the No.2311 working face of Changcun Mine as the research object,this paper compares and analyzes the degree of surface subsidence caused by mining with and without bed separation grouting through probability integral prediction and discrete element numerical simulation.The results show that surface subsidence can be effectively controlled.The technology can effectively control surface subsidence and improve the recovery rate of coal resources.
