摘　　要：为解决近距离煤层群同采工作面强矿压显现的问题,以山西灵石华苑煤业有限公司9104工作面、10104工作面为工程背景,基于土力学相关理论建立合理错距分析模型,确定工作面压外式布置合理错距为25.86m。现场试验表明10104工作面巷道变形显著降低,巷道底鼓量小于250mm,煤柱帮移近量小于200mm,为类似条件工作面布置提供技术借鉴。In order to solve the problem of strong mine pressure in the working face of close distance coal seam group,taking the 9104 working face and 10104 working face of Shanxi Lingshi Huayuan Coal Industry Co.,Ltd.as the engineering background,based on the theory of soil mechanics,a reasonable staggered distance analysis model is established,and the reasonable staggered distance of the external pressure layout of the working face is determined to be 25.86 meters.The field test shows that the deformation of the roadway in the 10104 working face is significantly reduced,the floor heave of the roadway is less than 250 mm,and the displacement of the coal pillar is less than 200 mm,which provides technical reference for the layout of the working face under similar conditions.
