In situ rock stress measured by supersonic wave and its analysis
-
摘要: 在对平顶山八矿-430m和-530m水平3个测站的原岩应力进行超声波检测的基础上,用多元非线性声波椭球模拟方法对矿井地应力场进行了分析。Abstract: In this paper, in situ rock stress are measured with supersonic wave at three points on the level of -430 and -530 meters in 8th Coal Mine at Pingdingshan, and then the general state of stress are analyzed with multi nonlinear supersonic wave ellipsoid simulating method.
