摘　　要：先介绍了跳汰法、重介法等井上煤矸分选方法及其弊端,并对煤矸液压式自动分选机、弹力式煤矸分选机、旋转冲击式井下煤矸分离机、井下选煤系统等井下煤矸分选设备与分选方法进行介绍。最后总结了井下煤矸分选的优点,认为其具有广泛的应用前景。In this paper separate method for coal and gangue on the ground such as jigging,sink and float method was studied.Because all this methods are not suitable for underground using,this paper focus on the separate method underground such as automatic hydraulic separator,elastic separation of coal and gangue,rotating impact crush separator and coal preparation system underground.The meaning of separate method for coal and gangue underground was concluded at the end of this paper and the underground method has a wide foreground.

关 键 词：跳汰法 重介法 冲击破碎 煤矸分选
