Abstract: Longwall mining under coal pillars in close-distance goaf will be influenced by the remained coal pillars at upper coal seam and the dynamic pressure of the coal face.In view of the characteristics that the roof and floor of No.9 coal seam of some coal mine in Urumqi are soft，the jointed support scheme of collaborative support of beam and cable + grouting reinforcement of top and bottom corners，side-wall bolting + bottom anchor and beam support+ full-section net is proposed after analyzing the failure mechanism of surrounding rocks，namely the integrated treatment of roof，floor and side-wall.Arranging the pressure-relief hole in the roadway is conducive to transfer high stress into the deep tunnel and improve the stress condition of surrounding rocks and support structures.The practice has proved that these measures effectively solved the issues such as roof damage in mining roadway，coal wall spalling and floor heaving etc..Approaches adopted in mining process，including reducing mining height，inclining working face，accelerating working face through coal pillars greatly improved the production conditions in working face，and ensured the mining safety.
