摘要
本文实验研究了山东某矿煤矸石的岩石组成、矿物组成、化学组成、粒度、强度，煤矸石中Ａｌ２Ｏ３含量、热值与煤矸石粒度、强度的关系．对该矿煤矸石选择性破碎分选进行实验研究．
The rock composition,mineral composwition,and chemical composition as well asThe size and strength of gangue are discussd.The relations between the Al2O3 content,calorificvalue and size and strength of the coal gangue are analyzed.The possibility and importance of alternative crush separation of gangue are also studied.
