摘要
应用空心包体式三轴应变计,采用钻孔应力解除法系统地对淮南矿区现有主采煤层进行地应力现场实测,得到不同位置和埋深的实测地应力数据。通过对实测数据的系统分析,得出矿区范围内地应力场的分布规律。
The field measurement is systematically carried out by drilling stress - relief method with hollow inclusion triaxial strain gauge in primary main coal seam of Huainan Mining Area, and actual survey ground stress data at different positions and depths are achieved. Distribution laws of ground stress field are obtained by systematically analyzing testing data.
