摘　　要：以某矿回采巷道位于上部开采煤层形成煤柱的技术条件为例,从围岩应力控制的角度出发,提出了在被保护巷道一侧掘进巷道,将要保护巷道周围较大的围岩应力转移到新开掘巷道附近,使要保护巷道处于良好的应力环境,从而有效保护巷道的新技术,并利用数值模拟的方法对主要技术参数进行了分析确定。Illustrated a roadway under the remnant pillar formed by upper coal mining,from the view of stress controlling,the paper presented a new technique of stress transfer to protect the roadways,that was digging a tunnel beside the roadway protected.It made the high surrounding stress transferred to the roadways newly digged and the roadway protected was under a lower stress condition.Consequently realized to protect the roadways effectively.The major parameters were analyzed by using numerical simulation method.
