| 摘 要： | 贺西煤矿三采扩区集中回风巷因与34k4工作面距离较近,在34k4工作面回采时,三采扩区集中回风巷受采动影响,巷道出现底鼓、片帮等变形,就巷道变形规律进行分析,提出今后应注意和改进的措施。

| Abstract: | Because the centralized air return way in three-mining expanding area of Hexi Coal Mine is close to 34k4 mining face, it is affected by mining while the 34K4 mining face is mined, which leads to the deformation of floor heave, wall caving, etc. The deformation law of the roadway is analyzed, and the measures should be paid attention to and improved in future. |
