急倾斜近距离复合薄煤层合层开采实践

Mining Technology of Composite Thin Coal Seam with Steep Inclination and Close Distance

通过对李子垭煤矿急倾斜近距离复合薄煤层5102工作面开采条件及难度进行全面分析,结合国内急倾斜薄煤层和近距离复合煤层综合机械化开采实践经验,制定了针对5102工作面合层高效开采的技术方案,总结了急倾斜近距离复合薄煤层开采的实践经验,减少了煤炭资源浪费,为类似条件煤层开采积累了宝贵技术经验。

Based on the comprehensive analysis of working conditions and mining difficulty of 5102 working face of steeply inclined short-distance composite thin seam in Liziya coal mine, and combined with the practical experience of comprehensive mechanized mining of steeply inclined thin seam and close-distance composite seam in China, the technical scheme for efficient mining of composite seam in 5102 working face is formulated, and the practical experience of mining steeply inclined short-distance composite thin seam is summarized, which reduces coal consumption. The waste of resources has accumulated valuable technical experience for coal seam mining under similar conditions.
