摘　　要：为根本解决任楼煤矿动压巷道大面积严重失修状况,以巷道与开采煤层的空间关系作为巷道破坏分类的依据,介绍了各类动压巷道的破坏情况,从巷道布置与原岩应力方向关系、巷道围岩条件、地质构造影响、煤岩柱留设尺寸等方面探讨了巷道布置方式与动压巷道的破坏关系,提出了控制各类动压巷道破坏的巷道布置原则要保证巷道与开采煤层的合理空间关系。In order to fundamentally solve the large area serious failure condition of the mine dynamic roadway in Renlou Mine, the paper introduced the failure conditions of each dynamic roadway taking the space relationship between the mine roadway and the mining seam as the basis of the mine roadway failure classification. From the relationship between the mine roadway layout and the in-situ rock stress di- rection, the roadway surrounding rock conditions, the geological structure influences, the coal and rock pillar size left and others, the pa- per discussed the failure relationship between the roadway layout and dynamic roadway. The paper provided the mine roadway layout prin- ciples to control different dynamic roadway failures in order to ensure the rational space relationship between mine roadway and seam.
