Abstract: When cross measure dark inclined roadway pass through the mining face that is being worked above, it is necessary to rationally locate coal pillars and the stopping line so as to reduce the resource loss under the premise of protecting the safety and stability of the cross measure inclined roadway. This paper theoretically analyzes the stress distribution of surrounding rock and damage state of the floor during the extraction of the upper coal seam against 4102 long-wall panel of Shanxi Shenzhou Coal Mine. Based on the calculation results, the optimization is proposed. Compared with the layout of original working surface, the extension arrangement of the inclined shaft is determined when the 4102 long-wall face is in above. This can recover about 22,000 more tons of high quality main coking coal, which has considerable economic benefits for mines entering the resource depletion phase.
