煤矸石再生资源的基础性研究与应用

Foundation Research and Application on Renewable Resources Coal Gangue

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。主要通过对国内外煤矸石的综合分析,针对其特点得出煤矸石在不同领域应用的可行性。

The gangue is one kind of solid waste coal products which is produced in coal washing process. It not only contaminates water quality, but also generates harmful gas, and the great number of cumulate coal gangue has occupied more and more cultivated land, all of which have destroyed environment and ecology. The gangue is one kind of the renewable resources which can develop and save occupancy land, also can save large amount of natural resources. The problem of contaminating environment will be solved. Through the inner and outer report, the feasible study basing on the coal gangue in different fields was discussed.
