关于采区大巷过大面积采空区时支护方案的比选及应用

A large area of mining roadway goaf supporting scheme selection and Application

以临汾某矿井下采区大巷过采空区为例,结合目前国内的巷道支护的相关理论,通过对采空区支护方案的选取和经济对比,提出对采空区巷道采用锚索+W钢带联合支护的方案。

Taking the goaf of a mine underground roadway in Linfen as an example, combined with the current domestic theory of roadway support, through the selection and economic comparison of support schemes for goaf, the scheme of combined support of anchor cable and W steel band for goaf roadway is put forward.
