摘　　要：介绍了一种新型井下煤矸分选方法——弹道式煤矸分选。通过对斜碰撞过程中原煤(混矸)球的运动分析,推导出基于碰撞恢复系数的物料块反弹距离公式。运用计算机仿真对理论推导结果进行验证,并分析了理论推导结果和仿真结果出现差异的原因。A new method of separation of coal and refuse in underground,ballistic separation of coal and refuse,was introduced in this paper.A formula of rebound distance based on coefficient of restitution was deduced through kinematic analysis of raw coal(mixed gangue) in the process of oblique-impact.At last,the paper validated the theoretical result by computer simulation,and discussed the causation of difference between results in theoretical analysis and in computer simulation.
