摘 要: 错层位巷道布置开采厚煤层可以提高放顶煤的采出率,通过UDE-3.10数值模拟软件对某矿进行数值模拟,分析上覆岩层的移动情况和应力分布状态,得出了工作面两端头应力较高的结论,对顶煤的放出起到较好的作用,提高了顶煤的放出率。
关 键 词: 采矿工程;错层位;UDEC-3.10;数值模拟;应力分布

Abstract: Stagger thick seam mining roadway layout can improve the recovery rate of top coal. The paper performs numerical simulation to a mine by UDE-3.10 numerical simulation software, analyzes the movement and stress distribution of overlying strata, and obtains the result that the stress at two ends of the work surface are higher, which increases release rate of the top coal.
Key words: mining engineering; stagger arrangement roadway layout; UDEC-3.10; numerical simulation; stress distribution
