摘　　要：为研究采空区稳定性状态,借助数值模拟软件ANSYS对凡口铅锌矿采空区进行三维有限元数值建模分析,准确得出各中段分层的应力场,将该应力场与矿山矿岩抗压强度和抗拉强度作对比,判断该采空区是否存在失稳的可能,找出存在安全隐患的采场,据此提出相应的预警与建议,以便矿山进行有效的地压管理。In order to study the stability in mined-out area, the numerical simulation software ANSYS was used to analyze the three-dimensional finite element numerical modeling of the mined-out area in Fankou Lead-zinc Mine. The stress field for beds at the middle levels was obtained accurately and was corn pared with compressive strength and tensile strength of the ore rock to determine whether there is instability in the mined-out ar- ea, to find out the presence of potential safety hazards and to put forward the corresponding warnings and suggestions so that the ground pressure management in tbe mine can effectively made.
