摘要

在有明显冲击地压可能性的综放采场一般采用沿空留巷的巷道布置方式,但由于冲击地压的存在,沿空留巷存在底板冲击危险性。常规的卸压方法具有工程量大、工序繁琐的问题,且防治冲击地压效果不明显。本文通过研究沿空区段巷道底板冲击地压的影响因素及卸压方法,针对性地提出防治措施,从根本上降低防冲难度,为同类工程实践提供参考。
        in the fully mechanized caving mining field with the possibility of striking the ground pressure, the roadway arrangement way along the gob is generally adopted, but because of the existence of the rockburst, there is the risk of the floor impact in the roadway along the space.The conventional pressure relief method has the problems of large engineering volume and complicated process, and the effect of preventing and controlling rock burst is not obvious. In this paper, through the study of the impact factors of the floor impact pressure of the floor of the roadway along the empty section, the prevention and control measures are put forward to reduce the difficulty of the impact and provide reference for the practice of the same kind of engineering.
