摘要
介绍了钢铉钻孔应力计监测在南屯煤矿93上03工作面的应用情况,该方法实现了监测煤体内不同深度的应力值,确定最具诱发冲击地压的范围和危险区域。
Application of borehole stress gauge monitoring at the 93upper 03 face in Nantun duced. This realizes the monitoring of stress values at different depths in the coal body. This that are most prone to pressure bumps and the most dangerous zones.
