摘　　要：基于地质动力学原理,从大同矿区地质动力环境出发,采用绘图法将研究区划分为Ⅰ~Ⅴ级五个等级的断块;应用"岩体应力状态分析系统"构建应力计算模型,通过计算得出应力分布特征;揭示了构造应力场对冲击地压的控制作用,为矿井高集中应力区域冲击地压的防治供理论依据。Based on the principle of geodynamics, starting from the geodynamic environment of Datong mining area,the study area is divided into five grades of fault blocks of grade I-V by means of drawing method;the stress calculation model is constructed by using the "rock stress state analysis system", and the stress distribution characteristics are obtained by calculation;the control effect of the structural stress field on the rock burst is revealed, which provides the theoretical basis for the prevention and control of rock burst in the high concentrated stress area of the mine.
