Abstract: Taking six mining area No.3 coal seam 6204 working face as engineering background, the paper researched the stress distribution laws of the lower part of the stope by using the theoretical analysis and numerical simulation, obtained that the lead abutment pressure peak would gradually increase with the face constantly close to the edge of the coal pillar. The lead bearing pressure of coal pillar under working face was far greater than abutment pressure under gob area. Therefore, when mining is in the case of the upper coal pillar, the impingement warning and corresponding prevention measures should be done to prevent the occurrence of rockburst.
