摘　　要：鸡西矿业集团公司城山煤矿东一3#煤走向二面回风巷及走向三面回风巷采用相同煤柱护巷。在不同支护强度的条件下,巷道状况有着非常大的变化。经过对比分析认为,在采用小煤柱掘巷时,必须适当加强两帮的支护强度,提高巷道两帮的支撑能力,以便更好地保证巷道的可利用空间。In Chengshan Coal Mine, Jixi Mining Industry Group Comp. , the same protective pillars were used in the strike No. 2 face wind roadway and the strike No. 3 face wind roadway, in No. 3 coal seam of east No. 1 mining area. On the different conditions of support strength, the roadways conditions changed greatly. When small coal pillars were used to protect roadways, the support strength of two sides must be suitably strengthened, the support capacity of two sides was raised, in order to ensure the useful space of roadways better.
