杜家村矿地应力测试试验

The test experiment of ground stress in Dujiacun mine

采用空芯包体套孔应力解除法进行了杜家村矿地应力测量,测试表明:杜家村煤矿最大主应力方向为近似水平方向,其值约为竖直应力的1.04～1.38之间,最大主应力的走向方位角在184°～205°之间,为北东—南西方向。

This paper used the empty pericardium body stress relieving method to test the ground stress of Dujiacun mine. Testing shows that the direction of maximum main stress of Dujiacun mine is approximate horizontal direction, the value is about 1.04 - 1.38 times of the vertical stress. The trend azimuth angle of maximum main stress is 184-205, NE-SW direction.
