摘　　要：通过钻孔煤粉量、围岩松动圈、巷道表面位移及顶板动态变化规律的实测 ,分析确定了平煤集团十三矿合理煤柱留设尺寸。结果表明 ,在该矿煤层条件下合理的煤柱尺寸可由原来的 1 5 m减少到 8m。Reasonable width of coal pillars is determined by a serial of measuring ways , such as borehole coal dust, loosen zone of surrounding rock , surface displacement of roadway and dynamic deformation of coal roof in No.13 coalmine, Pingdingshan mining group corporation. The results indicate that reasonable width of coal pillars may reduce from 15m to 8m in terms of the condition of coal seam, No.13 coalmine.
