阳煤五矿动压巷道测量技术方案和管理方法研究

Research on dynamic pressure roadway measuring technology of Yangquan NO.5 Coal Mine

阳煤集团五矿8407工作面留设10m小煤柱。小煤柱的留设造成靠近采空侧巷道在掘进过程中压力大、容易变形,顶板的测量控制点位移,导致中腰线出现偏差,会使掘进巷道出现偏差。为此加强测量管理,保证测量精度,强化动压巷道安全管理非常重要。

The8407working face is used to set10m small coal pillars of Yangquan Coal Group NO.5.The small coal pillar results in large pressure and deformation easily in the roadway near the gob side,and the displacement of the control point in the roof measurement results in the deviation in the middle and the waistline,which will lead to the deviation of the driving tunnel.Therefore,it is very important to strengthen the measurement management,ensure the measurement accuracy,and strengthen the safety management of the dynamic pressure roadway.
