煤矿地应力测试及应力场反演分析

根据地应力测试的基本概念及原理,结合实际地应力测试工作,介绍了地应力测试过程中的测量原理、测试设备与现场测量方法,并对测试结果进行了分析。在此基础上,根据地应力的测试结果,运用多元线性回归的方法进行了地应力场反演,并以西二采区9号煤反演结果为例进行了分析,结果表明,该采区3个工作面位于应力集中区,冲击危险性较大。

Coal Mine Ground Stress Test and Stress Field Inversion Analysis

According to the basic concept and principle of the ground stress test, combined with the actual ground stress testing, the measuring principle, testing equipment and measuring method of ground stress test were introduced, test result was analyzed. Based on this, according to the ground stress test results, multiple linear regression method was used to conduct ground stress field inversion, No. 9 coal seam in west No. 2 mining area inversion result was analyzed, the result showed that the 3 working faces in the mining area were located in area of stress concentration, with big shock hazard.
