摘要
以晋华矿"两硬"薄煤层为研究对象,分析了薄煤层开采的特点,对该矿巷道设计、设备选型、巷道支护、采煤工艺进行了研究,实地跟踪调查了影响薄煤层开采效率的主要因素并做了详细分析,研究方法对同类型矿井有一定参考价值。
The hard coal and hard roof thin coal seam of Jinhua Mine was taken as example, the characteristics of thin coal seam mining was analyzed, the mine roadway support design, equipment selection and mining technology were studied, the main factors that influencing efficiency of thin coal seam mining was investigated and a detailed analysis was made, the study method was of certain reference value to similar mines.
