论文摘要：	研究球型镶齿滚刀破岩过程中刀盘转速、钻压、镶齿数、刀盘间距以及贯入度5 种因素对破岩比能的影响，利用ABAQUS 有限元计算软件，建立双排滚刀直线切割围岩的动力显式模型；基于正交试验法，设置五因素四水平正交试验L16(45)，通过极差分析和方差分析找出不同因素变化对破岩比能的影响规律，并对比分析最优组合和最不利工况下滚刀滚动力和破岩效果。研究结果表明：影响滚刀破岩比能因素的主次顺序依次是钻压、刀盘排距、转速、刀齿数和贯入度；适用于中风化凝灰岩互层的钻具参数为转速12.56 m/s，钻压25 kN，刀齿数34 个，刀盘排距35 mm，贯入度1 mm，此时的破岩比能为0.382 8 MJ/m3，优化效果较好。
