为了提高冲击危险评价精度,基于三维地应力场反演技术进行相关研究,以郭家河煤矿Ⅰ盘区为研究对象,在地质构造特征分析、煤岩物理力学试验和矿井地应力实测的基础上,根据多元线性回归原理对三维地应力场进行数值模拟反演,获得研究区域内三维地应力场的地应力;在综合考虑构造应力和采动应力影响的情况下,实现了对Ⅰ盘区冲击危险的宏观评价和对局部范围内冲击危险的精确评价,共划分出11个强冲击危险区和5个中等冲击危险区。

In order to improve the evaluation accuracy of the mine strata pressure bumping danger, a related study was conducted based on the inversion technolo gy of the 3D ground stress field. Taking No. I panel of Guojiahe Mine as a study object, based on the analysis on the geological tectonic features, coal and rock physic al mechanics test and the mine ground stress measurement, according to the multiple linear regression principle, a numerical simulation inversion was conducted on th e 3D ground stress field. The ground stress of the 3D ground stress field within the study region was obtained. Under the comprehensive consideration on the tectonic s tress and mining stress influences, a macro evaluation on the mine strata pressure bumping danger from No. I panel and the accurate evaluation on the mine strata pr essure bumping danger in a local section was realized. There were 11 strong mine strata pressure bumping dangerous zones and 5 medium mine strata pressure bumpi ng dangerous zones divided.
