摘要

在不同的地质条件下,确定合理的综采放顶煤开采工艺参数对资源回收率有着重要影响。结合A兼并重组煤矿工程实际,分析了矿井地质条件及采煤方法的选择,详细探讨了综采放顶煤开采工艺参数的确定。实践证明,综采放顶煤开采工艺参数设计较为合理,工作面安全性和回采率得到了有效保障,可为类似煤层条件工作面开采提供借鉴。
        Under different geological conditions, determining reasonable parameters of fully mechanized top coal caving mining has an important impact on resource recovery. Combining with the engineering practice of A Coal Mine with merger and reorganization, this paper analyzed the geological conditions of the mine and the selection of mining methods and discussed in detail the determination of mining parameters of fully mechanized top coal caving mining. Practice has proved that the design of technological parameters of fully mechanized top coal caving mining is reasonable, and the safety and recovery rate of working face have been effectively guaranteed, which can provide reference for mining of the working face with similar coal seam conditions.
