| Abstract: | The orientation and amplitude of thinning and thickening zones of main mining coal seams in some mining areas of Qianling coal mine are studied,through observation and research on the features and distribution regularities of slip sheet structures.The results indicated the development situation of soft beds and slip sheet structures in coal seams No.3 1-5 and the thinning or thickening regularities in the coal seam No.4,which provided geological information. |

| Keywords: | coal seam slip sheet structure soft bed forecast |
