摘　　要：义棠矿9号煤层与10号煤层为近距离同采煤层,为了确定两煤层同采工作面的合理错距,采用现场实测的方法对9号和10号煤层的矿压规律进行分析掌握,并对不同错距条件下巷道围岩变形情况进行统计分析,最终确定同采工作面合理错距为30~50m。The No.9 coal seam and the No.10 coal seam are simultaneous mining coal seam.In order to determine the reasonable staggered distance of the simultaneous mining face in the close distance coal seams of No.9 and No.10,the field test method is used to analyze the ore pressure law of No.9 and No.10 coal seams.The statistical analysis of the surrounding rock deformation of the roadway under different distance conditions is carried out,and the reasonable staggered distance of the simultaneous mining working face is determined to be 30~50m.
