煤矸石是一种含炭比较高的页岩,发热量一般在1000—2000千卡/公斤。如不加利用就得运出堆存,不但增加采煤成本,占用大量土地,而且污染环境.因此对煤矸石利用不加研究和处理,将会给煤炭生产、资源利用、环境保护带来不可估量的严重后果。从目前国内外资料看,煤矸石利用大致有如下几方面。
Coal gangue is a kind of shale with high carbon content, and the calorific value is generally 1000-2000 kcal/kg. If they are not used, they have to be transported out of storage, which not only increases the cost of coal mining, occupies large amounts of land, but also pollutes the environment. Therefore, the lack of research and treatment of coal gangue will bring about incombustibility to coal production, resource utilization and environmental protection. The serious consequences of the assessment. From the current domestic and international data, the use of coal gangue roughly has the following aspects.
