摘要
煤矸石是采煤和选煤过程中的排弃物 ,煤矸石长期堆存 ,不仅占用大量土地 ,同时污染大气和地下水质 ,长时可形成自燃。利用煤矸石生产建筑材料 ,可节约大量土地 ,具有很好的环境、社会和经济效益。本文研究了在利用煤矸石制砖、生产水泥时对煤矸石的化学成分、工艺性能等方面的要求 ,并给出了一些指导性的结论和经验配方。本文的结论对解决利用煤矸石生产建筑材料可能面临的问题时 ,有一定的参考价值。
Gangue is a kind of discharge material in the process of excavating coal and picking coal.With the long time stacking,gangue may not only engross a great deal of land but also pollute the air and underground water and induce spontaneous combustion.Producing construction material by using gangue can save much soil and have very good benefit in the field of environment,society and economy.The demand on gangue's chemic component and technical capability in the process of making brick and producing cement is studied in this paper.Then,some guidance conclusions and experience prescription are presented.The conclusions have some reference meaning in solving the problem possibility brought in the production of construction material by using gangue.
