摘　　要：针对大力公司上部一座煤层受下部山青、野青煤层多次采动影响的实际情况,运用上行开采比值判别法、"三带"判别法、数理统计法及围岩平衡法等对一座煤层5301工作面复采可行性进行分析,并对下部煤层开采后覆岩塑性区及应力场、位移场分布和工作面复采矿压显现规律进行了模拟研究,结合现场矿压监测证明极薄煤层上行复采的可行性。Aimed at the actual situation of Dali company the upper Yizuo coal seam influenced many times by mining the lower Shanqing and Yeqing coal seams,upward mining ratio method, ＂three zones＂ discrimination method, mathematical statistics method and balance method of surrounding rock were used to analyse feasibility of 5301 working face mining in Yizuo coal seam, and plastic zone and stress field, displacement field distribution of surrounding rock and the working face mining pressure behavior law were researched by numerical simulation after the lower coal mining, combined with the mining pressure monitoring to prove the feasibility of extremely thin coal bed upward mining.

关 键 词：极薄煤层 上行开采 复采 可行性
