摘要
研究了煤矸石的岩石组成、矿物组成、化学组成、粒度、强度，以及煤矸石中Ａｌ＿２Ｏ＿３含量、热值与煤矸石粒度、强度的关系，论述了煤矸石选择性破碎分选的可行性及其意义。
Abstract The,rocks,minerals and chemical com-positions in the coal gangues have been in-vestigated.The relation between size,strength of the gangues and their content ofAl_2O_3 will be discussed.The possibility ofselective crushing and separation of coalgangues will also be introduced.
