山西某矿巷道围岩地应力测试研究

Test and Research on Crustal Stress in Roadway Surrounding Rocks in a Coal Mine in Shanxi

为了矿井生产和建设的接续,某矿正准备进行15#煤的盘区规划与开拓。对矿区15#煤进行全面系统的地质力学测试实验和数据研究,得到的结论是此矿15#煤所测区域最大水平应力最大值为13.47 MPa,最小水平主应力最大值为7.44 MPa,垂直主应力最大值为8.55 MPa,从量级上划分所测区域地应力水平属于中低地应力。

In order to maintain the coal mine’s production and construction,the coal mine is preparing the planning and exploiting of the plane of No.15 coal.After systematic geomechanical tests and data studies into the mine’s No.15 coal,the conclusions are as follows:in the tested districts of No.15 coal,the maximum of the highest horizontal stress is 13.47MPa,the minimum of the lowest horizontal stress is 13.47MPa,and the primary vertical stress 8.55MPa.The crustal stress level in the tested district is classified into the low-middle crustal stress range.
