摘要
煤矸石是煤炭生产和洗煤过程中伴生的一种固体废弃物。废弃的煤矸石不仅污染水质,自燃后生成有害气体,污染空气。大量堆积的煤矸石侵占了越来越多的耕地,构成了对生态和环境的双重破坏。煤矸石又是一种可以开发和利用的再生资源,不仅可解决煤矸石占用土地、污染环境的问题,而且还可以节省大量天然资源。
The gangue is one kind of solid waste that coal produces and accompanies unprocessed in coal washing process,which not only contaminated water quality,but also generates a harmful gas,contaminates airand the great quantity of accumulating has invaded and occupied more and more cultivated landall of which doublenessly have destroyed environment and ecoal.The gangue is one kind of the renewable resources which can develop and resolve saving occupancy land ,the problem of contaminating environment, and can save large amount of natural resources.
