摘要
针对研究矿井的特殊地质条件与生产实际,采用理论分析和数值模拟的研究方法,对2#煤层蹬空开采的可行性进行了论证分析。结果表明:由于2#煤层底板为坚硬岩层,在一定程度上受3#煤层保护煤柱的支撑作用,且2#煤层开采时间较为久远,2#煤层在理论上满足蹬空开采的要求。
Based on the study of the special geological conditions and practical production, by methods of theoretical analysis and numerical stimulation, the feasibility of mining above hollow in 2#coal seam in close distance was argued and analyzed. The results indicate that： the floor of 2#coal seam is hard rock which is partly supported by protective coal pillar of the 3#coal seam, and the production time of3#coal seam is relatively long. The 2#coal seam meets the requirements of mining above hollow in theory.
