摘　　要：地下开采中地压分布与转移随开采空间变动而变动,不同的开采顺序会带来不同的围岩稳定性。本文从围岩稳定性出发,对三种阶段中矿块开采顺序(从中央到两翼、从两翼到中央、从一翼到另一翼)进行了数值模拟分析研究,寻找到最有利于围岩稳定的阶段矿块开采顺序,从而使地下开采顺序选择从传统经验法上升到有限元数值模拟定量分析及优化阶段。Distribution and transfusion of the geostatic pressure variate in company with mining space in underground mining.Different mining sequences bring about different stability of surrounding rock.This thesis numerical modeled and analyzed three mining sequences(from centre to both sides,from both side to centre,from one side to another side) and found the mining sequences that is most in favor of stability of surrounding rock.It makes choosing mining sequences rise from the traditional experience method to FEM numerical modeling and optimization quantitatively.
