摘要: 基于飞矸法向碰撞恢复系数的数字特征,推导出飞矸切向碰撞恢复系数的数字特征。分析参数的随机性对飞
矸运动特征量的影响,得到飞矸弹跳高度和动能的均值曲线。结果表明,飞矸运动参数的随机性对飞矸运动特征量具有
一定程度的影响,且随着碰撞次数的增加,参数的随机性对飞矸弹跳高度和动能均值的影响逐渐增大。

Abstract: Based on the numerical characteristics of the normal collision recovery coefficient of flying gangue, the numerical
characteristics of the tangential collision recovery coefficient of flying gangue were derived. The influence of parameter randomness
on the characteristic quantity of the flying gangue motion was analyzed, and the mean curve of the rebound height and kinetic
energy of flying gangue was obtained. The results show that the randomness of the motion parameters of flying gangue has a
certain influence on the motion characteristics of flying gangue, and the influence of the randomness of the parameters on the
mean rebound height and kinetic energy of flying gangue increases with the increase of collision times.

Key words: flying gangue; stochastic parameter; steeply dipping coal seam; random motion
