Abstract Based on geological condition of thin coal seam fully mechanized working face in Xinyi Mine, advanced pillar and coal body stress monitoring were adopted to study mining area support pressure distribution feature of the working face. The result showed that basic roof first weighting interval of 13306 thin coal seam working face was 26.8 m, periodic weighting average interval was 17.8 m, with small dynamic factor, abutment pressure peak value position was ahead of coal wall 1~8 m, with low pressure strength, which provided reference and guidance for safe recovery mining of similar working face.
