摘　　要：针对寺河煤矿大采高工作面大断面(宽5.5m×高4.0m)回撤通道具体地质特征,提出了锚梁网索联合支护的方案,并采用有限差分数值计算程序FLAC2D5.0对巷道支护效果进行了较深入的分析。结果表明,巷道采用联合支护技术是合理的,所采用的支护参数完全能够满足工作面设备的顺利回撤,可为该矿区类似条件下大断面巷道支护提供参考。According to the certain geological features of the large cross section （wide 5. 5 m × high 4. 0 m） equipment removing gateway for the high mining height coal mining face in Sihe Mine, the paper provided a combined support plan with the bolt, beam, steel mesh and anchor and in detail analyzed the mine roadway support results with the finite difference numerical calculation program FLAC2D5. 0. The results showed that the combined support technology applied to the mine roadway ware rational and the support parameters applied could be fully to meet the successful removing of the coal mining face equipment, which could be the references to the mine large cross sectional roadway support with the similar conditions in this mining area.
