摘　　要：通过对石窑店煤矿215205综采工作面超前煤体及区段煤柱应力进行实测和理论分析,掌握了该条件下煤体应力分布特征。结果表明:该工作面超前支承压力峰值位于煤壁前方3～4m,影响范围约10.25～13.5m,工作面所留设20m区段煤柱可以满足支护要求。所得成果对类似地质条件下工作面超前支护范围和煤柱合理留设有指导作用。With the site measurements and theoretical analysis conducted on the stresses of the advance coal seam and sectional coal pillars in No.215205 fully mechanized coal mining face of Shiyaodian Mine,the stress distribution features of the coal seam under the conditions were understood.The results showed that the advance support pressure peak of the coal mining face was in front of the coal wall with a distance of 3~4m,the influence scope was about 10.25~13.5m and the sectional coal pillar with 20m set in the coal mining face could meet the support requirements.The achievements obtained would have the guidance role to the advance support scope and the coal pillar rationally set of the coal mining face under the similar geological conditions.
