针对山西晋城成庄煤矿区的地形地貌特征,考虑地应力形成的基本原理,结合矿区地应力实测资料,建立三维计算模型,通过多元线性回归分析方法求得各基本应力场的回归系数,最后进行线性叠加,较为准确的反演出了煤矿区的初始地应力场。反演的结果表明,该区域的应力场特征表现为不仅仅是以自重应力为主导,同时还受到水平的构造应力场的综合作用。
According to the topographic and geomorphological features of Chengzhuang Coal Mine in Jincheng, Shanxi Province, considering the basic principle of formation of ground stress and combining with measured data of in-situ stress in mining area, a three-dimensional calculation model was established and the regression coefficients of each basic stress field were obtained by multiple linear regression analysis Linear superposition, a more accurate inversion of the initial stress field of coal mines. The inversion results show that the stress field in this region is not only dominated by self-weighting stress but also by the horizontal tectonic stress field.
