(College of mining and Safety Engineering Shandong University of Science and Technology,Shandong Qingdao 266590) Abstract The roadway driving along the roof for large embedded depth often had irregular failure in inclined coal seam at one coalmine, in order to analyze the failure law of roadway, this paper adopted the method of elastic-plastic analysis and numerical simulation to study the stress, plastic zone and deformation of roadway in inclined coal seam when the embedded depth of roadway is 1000 m. it can be concluded that the stress peak position and plastic region of high side are greater than the low side, the low side in the upper and high side in the lower part are the large area of roadway deformation. Based on the damage characteristics, this article puts forward the support scheme, which is combined support of bolt-mesh-anchor and reinforce the support to the high side with the anchorage cable. It obtains a good supporting effect and provides a new way for support design of large embedded depth roadway in inclined coal seam.
