摘　　要：以张北煤矿6煤为工程背景,采用理论计算,得出沿空掘巷合理煤柱宽度,并运用FLAC2D数值模拟软件对沿空掘巷不同煤柱宽度条件下,巷道两帮应力及巷道顶板位移和帮部位移的变化规律进行分析研究,得出适应工程实际的参考煤柱宽度。Take No.6 coal seam of Zhangbei Coal Mine as the engineering background,the theoretical calculations are adopted to obtaine a reasonable coal pillar width in driving roadway along gob,and numerical simulation software FLAC2D is used to analyse variation of the stress of the roadway between two groups and displacement of the roof and roadway＇s sides under the conditions of different widths of coal pillar on the driving roadway along goaf.The actual reference of coal pillar width is obtained for the project of driving roadway along gob.

关 键 词：煤柱宽度 数值模拟 沿空掘巷
