摘　　要：矿体开采将引起周围岩体应力的重新分布,当二次应力大于岩体的强度,将使岩体破坏,导致地压灾害。地压灾害的发生还与岩性、采场结构参数及回采顺序有关,不同的回采顺序具有不同的地压显现规律。运用数值模拟软件FLAC3D,对某矿进行了多矿房同采条件下的围岩稳定性分析,取得了良好的模拟效果。The surrounding rock mass stress can be redistributed by orebody mining,the rock mass can be damaged and the ground pressure disasters can be caused under the conditions of the secondary stress is greater than the strength of the rock mass. The occurrence of ground pressure disasters are related to the lithology,stope structure parameters and stoping sequence,the difference of stoping sequence with difference regularity of underground pressure occurrence. Based on FLAC3 Dnumerical simulation software,the stability of surrounding rocks under the conditions of multi-chambers mining is analyzed,and the good simulation effect is obtained.
