摘要
为解决胡底煤矿1103开拓巷在高应力、大断面条件下巷道支护这一难题,结合1103巷围岩地质条件,通过理论计算,提出了“锚杆+锚索+锚网+喷浆”支护方案及护参数。后期矿压监测显示,该支护方案及参数合理,满足安全生产的需要。
In order to solve the problem of roadway support in 1103 development roadway of Hudi Coal Mine under the condition of high stress and large cross section,combined with the geological conditions of surrounding rock of 1103 roadway,through theoretical calculation,the support scheme and protection parameters of"bolt+Cable+anchor net+shotcrete"are put forward.Later mine pressure monitoring shows that the support scheme and parameters are reasonable and meet the needs of safe production.
