近距离煤层上行开采设计优化探究

Exploration of Optimization Design of Upward Mining for Close Distance Coal Seam

近距离煤层作为中国广泛存在的一种煤层赋存形式,如何实现其高效开采一直是矿井生产效益提升的关键问题之一。结合具体工程实际,分析了作业面巷道布设存在的问题,针对上行作业面回风巷道的合理布设开展不同方案的比对分析,并最终确定外错式巷道布设方式更为经济适用,希望能为其他矿井相关施工的开展提供借鉴。

Close distance coal seam is a widespread form of coal occurrence in China and how to achieve efficient mining has always been one of the key issues for improving mine production efficiency.Combining the specific engineering practice,this paper analyzes the problems in roadway layout,analyzes and compares different schemes for reasonable layout at the upward wor-king face in return roadway and ultimately determines that the alternately exterior layout is more affordable,which hoped to pro-vide reference for the related construction of other mines.
