摘要
N1206工作面为孤岛工作面,两侧为采空区,巷道掘进期间矿压显现明显。通过在巷道两帮施工卸压钻孔来降低巷道矿山压力,优化巷道支护设计,巷道围岩变形得到明显的控制。
The working face of N1206 is an isolated working face, and the two sides are goaf. During tunneling, the strata pressure is obvious. Through the construction of pressure relief boreholes on both sides of the roadway to reduce the mine pressure and optimize the design of roadway support, the deformation of roadway surrounding rock is obviously controlled.
