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。
Taking the 6 coal in Zhangbei Coal Mine as the engineering background, the reasonable coal pillar width of the roadway driving along the goaf was obtained by theoretical calculation. The numerical simulation software FLAC2D was used to simulate the stress of two sides of the roadway and the roof of the roadway Displacement and gang displacement of the law of analysis, obtained to adapt to the actual engineering reference pillars width.
