摘　　要：在分析近距离煤层群上行开采机理与可行性的基础上,为尽可能减少多煤层高瓦斯矿井开采期间瓦斯事故,探讨了开采多煤层保护层的方法.通过贵州盘江矿区金佳和月亮田两个矿井实践,采用上行卸压开采的技术方案,解决了开采中所产生的瓦斯突出、煤尘爆炸等问题,并在总结生产实践的基础上,提出了合理的开采方案及适用条件,研究成果对煤矿安全高效生产及相关环境控制都具有重要的意义.The mining of coal seams of the protective layer method was studied,in order to reduce high-gas coal mine gas accident during mining,based on the mechanism and feasibility analysis of upstream mining seams.Through the field practice of two coal mines Guizhou Panjiang Jinjia and the Yueliangtian,the mining gas outburst and coal dust explosion were properly solved by the use of upstream relieving mining technology,and a reasonable mining plan and applicable conditions were proposed based on the practice summary.The study is of great significance to the safe and efficient production and environmental control.
