摘　　要：地应力是引起采矿工程围岩、支护变形和破坏、产生矿井动力现象的根本作用力。随着采矿规模的不断扩大和不断向深度发展,地应力的影响愈加严重。由于地应力的影响,地下巷道和采场的坍塌破坏以及冲击地压等矿井动力灾害时有发生。因此,为了确保巷道围岩得到有效控制,实现矿井安全高效开采,本文根据营盘壕矿井地应力实测资料及地质构造条件,通过多元线性回归分析,建立了合适的FLAC3D模型,反演了该矿区先期开采地段的初始地应力场,研究结果对工作面方向布置及防治冲击地压灾害等均具有重要意义。Ground stress is the fundamental force that causes the deformation and failure of surrounding rock and support, and the dynamic phenomena of mine. With the continuous expansion of mining scale and continuous development, the influence of ground stress is more serious. Due to the influence of ground stress, the underground roadway and stope collapse and rock burst and other dynamic disasters occur. Therefore, in order to ensure the effective control of roadway surrounding rock, to achieve safe and efficient mining, according to the measured data of geostress and camp trench mine geological conditions, by using multivariate linear regression analysis, the establishment of a suitable FLAC^3D model, the inversion of initial stress field of the mining exploita- tion area, the results of the working face direction and prevention of rock burst disasters are of great significance.
