摘要
针对伊田矿1101工作面沿空掘巷实际地质条件,巷道围岩强度较低,稳定性差,支护管理困难。基于悬吊理论,对巷道围岩支护参数进行分析计算,合理确定支护参数,现场取得良好效果,为类似条件下巷道支护提供一定借鉴意义。
Aiming at the actual geological conditions of gob-side entry driving in 1 101 working face of Yitian coal mine,the surrounding rock of roadway has low strength,poor stability and difficult support management.Based on suspension theory,analysis and calculation of support parameters of surrounding rock of roadway,reasonable determination of support parameters,good results have been achieved on site,it provides some reference for roadway support under similar conditions.
