摘要
以某煤矿4煤为工程背景,采用理论计算,得出留小煤柱沿空掘巷合理的煤柱宽度,并采用数值软件模拟了不同煤柱宽度的沿空掘巷,确定了工程实际中的合理煤柱宽度。
Based on the engineering background of No. 4 coal mine,the coal pillar width of gob-side driving roadway with small coal pillar is obtained by theoretical and numerical calculation,and the coal pillar width suitable for practical engineering is determined.
