山西晋城煤矿区初始地应力场反演分析

Inversion Analysis of Initial Geostress Field in the Coal Mine Area of Shanxi Jincheng

摘要: 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。

Abstract: Aiming at the topography features of Chengzhuang Coal Mine Areas in Shanxi Jincheng, the basic theory of the geostress formation was considered. Combined with the geostress measured data, the 3D calculation model was established. Through the method of multiple liner regression analysis, and all the regression coefficients of the basic stress field could be worked out. Finally, the linear superposition was conducted, and the initial geostress field of coal mine areas was inversed accurately. The inversion results showed that the stress field of this region was characterized both dominated by the self-weight stress and comprehensively effected by the horizontal tectonic stress field.
