摘　　要：斜沟煤矿生产能力大,采掘面数量较多,彼此受到采掘扰动强烈,巷道底鼓加剧,围岩变形长期得不到稳定,加大了巷道的支护难度。斜沟煤矿18505工作面皮带巷受到18503工作面回采采动和采空区侧向支承压力的影响。叙述了18505工作面皮带巷支护的工程背景,分析了其巷道支护设计及矿压监测结果。The extractive disturbance is strong and roadway floor heave is aggravated due to large production capacity and large number of excavated faces, which caused the deformation of the surrounding rock is unstable for long time, and the roadway support is more difficult in Xiegou Coal Mine. The belt roadway at 18505 face is influenced by mining and lateral of abutment pressure of 18503 face in Xiegou Coal Mine. This paper described engineering background of supporting in belt roadway at 18505 face and analyzed the design of the roadway support and the monitoring result of mine pressure.
