摘　　要：悬臂式掘进机进行煤矿截割的过程中,针对截线距对截割性能的影响作用进行分析,从而提高煤矿的截割效率。采用离散元分析的形式建立不同截线距的模型,并对截齿的截割阻力、截割阻力波动系数、截割比能耗进行分析,从而选取最优的截线距参数,提高煤矿的截割效率。In the process of coal mine cutting by cantilever type roadheader,the influence of cut-off distance on cutting performance is analysed to improve the cutting efficiency of coal mine.Discrete element analysis is used to establish the model of different cut-off distance,and the cut-off resistance,cut-off resistance fluctuation coefficient and cut-off specific energy consumption of the cut-off teeth are analysed,so as to select the optimal cut-off distance parameter and improve the cutting efficiency of coal mine.

关 键 词：截线距 截割阻力 波动系数 截割比能耗
