连采掘进巷道稳定性控制技术探讨

Discussion on Stability Control Technology of Continuous Mining Laneway

以寺河矿W2305工作面为背景,分析了连采掘进巷道群的稳定性和巷间煤柱的合理留设宽度,设计了连采掘进巷道强力锚网与锚索联合支护技术,并优化巷道支护作业流程,现场工程应用表明巷道变形仅占断面尺寸的很小比例,能够满足矿井生产服务需要。

Taking the W2305 working face of Sihe Colliery as the background,the paper analyzes the stability of the continuous mining and excavation roadway group and the reasonable width of the coal pillars between the roadways,designs the combined support technology of strong anchor net and anchor cable for the continuous mining and excavation roadway,and optimizes the roadway support operation process,which proves that the roadway deformation only accounts for a small proportion of the cross-sectional size,and can meet the needs of mine production services.
