Abstract: Aiming at the problem of narrow pillar design for roadway driving along goaf of short-distance coal seams group, using the methods of theoretical analysis and numerical simulation, the relationship among the rock deformation of roadway driving along goaf of short-distance coal seams group, the law of surrounding rock stress distribution, the stability of narrow coal pillar and the pillar width is studied. The study results show that the reasonable coal pillar width range is between five meters and eight meters under the condition of the project, The results have references to reasonable pillar design for roadway driving along goaf with similar conditions.

Key words: short-distance coal seams group, roadway driving along goaf, narrow pillar, numerical simulation
