摘　　要：为了探索老矿井在承压煤柱周边复杂应力区施工巷道的治理办法,以柴里煤矿23617工作面初掘切眼为例,对巷道顶、帮进行岩移观测,通过围岩应力分析、治理效果比对,推测并论证了围岩应力分布状况,总结了类似复杂应力区下施工巷道的治理经验。In order to explore the old mine in complex stress zone surrounding the pressure on the coal pillars measures for the management of the construction of roadway in early 23617 working face of coal mine digging in the wood cut,for example,to rock movement observation of roadway roof and help,through the analysis of surrounding rock stress,governance effect,speculation and demonstrates the surrounding rock stress distribution,summarizes the similar roadway construction under complicated stress zone management experience.
