西部矿区某大型矿井的地应力测量

为了加强对西部矿区地应力的研究工作,采用了空心包体应力解除法对西部矿区某煤矿进行了地应力测量,初步掌握了该煤矿地应力的分布特征,指出该区的地应力以水平构造应力为主,且均为压应力,而且在同一平面内地应力大小和方向没有发生突变,说明矿区的地应力场比较均匀。

Stress Detection of a Large Mine in Western Area

In order to strengthen the research on crustal stress in western mining area,the crustal stresses of a coal mine in western mining area was measured by the hollow inclusion stress-relief method,preliminary master the crustal stress distribution characteristics of the coal mine.It is pointed out that the crustal stress of this mine is dominated by horizontal tectonic stress,and all of them are compressive stress.Also there are no abrupt changes of the size and orientation of crustal stress in the same plane,which demonstrates that the crustal stress of this mine is relatively uniform.
