摘　　要：鉴于采煤过程中不同工艺的进刀方式对煤层块煤率的重要影响,采用数值分析的方式对三种不同进刀方式下形成的块煤率进行分析,确定了最优化的进刀方式及工艺参数,从而优化了煤层的开采工艺,提高了成煤的块煤率。In view of the important influence of different feeding methods on the lump coal rate of coal seam in the process of coal mining, the lump coal rate formed under three different feeding methods is analyzed by numerical analysis, and the optimal feeding methods and process parameters are determined, so as to optimize the mining technology of coal seam and improve the lump coal rate of coal formation.
