摘　　要：针对大斗沟煤矿5201巷在过X4陷落柱应力区期间,巷道出现顶板下沉、破碎、煤壁片帮、底板鼓起等现象,通过技术研究合理分析原巷道采取的锚网索支护、钢棚支护主要存在的技术难题,并根据实际生产情况提出了锚杆架棚支护,通过实际应用效果来看,锚杆架棚支护可有效控制巷道顶板离层现象,取得了显著的应用成效。In view of the phenomenon of roof sinking, crushing, coal wall side and floor bulging in 5201 roadway of Dadougou Coal Mine during the X4 collapse column stress area, the main technical problems of bolting and cable support and steel shed support adopted in the original roadway are analyzed reasonably through technical research.According to the actual production situation, the bolt frame shed support is put forward. According to the actual application effect, the bolt frame shed support can effectively control the phenomenon of roadway roof separation, and the remarkable application effect is obtained.
