岩石大巷在任何矿井都是离不开的。大巷施工中的最大安全隐患是矿山静压力。大巷在矿山静压力作用下能在短时间内发生位移、变形、料石破裂、脱落。这不仅直接威胁施工人员安全,而且形响施工速度。造成矿井采掘失调,接替紧张,难以保证均衡生产。因此对矿山静压力防治问题必须进行研究,不可忽视。本文就观山矿井-270m 水平料石砌旋大巷的矿山静压力防治措施作一介绍,供参考。
Rocky lanes are inseparable from any mine. The biggest safety hazard in the construction of the tunnel is the mine static pressure. Under the action of mine static pressure, the main road can displace, deform, rupture and fall off in a short period of time. This not only directly threaten the safety of construction workers, but also affect the construction speed. Causing mining disorders, instead of tension, it is difficult to ensure a balanced production. Therefore, the study on the prevention and control of mine static pressure must be studied and can not be ignored. In this paper, we will introduce the prevention and cure measures of the mine static pressure of -270m level stone rotary roadway in Guanshan mine for reference.
