摘　　要：随着矿山开采深度的增加,岩体所处的力学条件变得复杂,深部崩落法开采引起的地表沉陷规律不同于浅部。基于有限差分法和岩石力学理论,研究了崩落法开采过程中,上覆岩层的移动变形规律与应力场分布特征,研究结果可为深部矿体开采岩层移动角及地表沉陷范围的确定提供一定的借鉴。With the increase of mining depth,the mechanical conditions in which the rock body is located become complex,and the surface subsidence pattern caused by deep caving mining is different from that caused by shallow caving mining.Based on the finite difference method and rock mechanics theory,the movement deformation law and stress field distribution characteristics of the overburden in the process of caving mining are studied,and the research results can provide some reference for the determination of the rock movement angle and surface subsidence range in mining of deep ore body.
