摘 要:依据西铭矿8#煤层顶底板岩性及对现场煤柱受力变形分析,构建了煤柱理论计算力学模型,按照极限平衡理论推演出煤柱宽度计算式,确定了8#煤层煤柱合理宽度,为同类型煤层煤柱尺寸设计提供了理论依据。In this paper,based on the rock properties of the top and bottom of Coal Seam 8#in Ximing Coal Mine and the analysis of the stress deformation of the on-site coal pillar,a theoretical calculation mechanical model of the coal pillar is constructed.According to the limit equilibrium theory,the calculation formula for the width of the coal pillar is derived,and the reasonable width of the coal pillar in Coal Seam 8#is determined,which provides a theoretical basis for the design of the size of the coal pillar in the same type of coal seam.
