通过对煤矸石各种危害情况的分析发现,堆积的煤矸石山会污染土壤,引发沙尘暴,占用宝贵的土地资源,还会进一步破坏生态景观,同时还会导致地质灾害的发生。为了达到煤矸石的资源化利用,多方都致力于探索煤矸石的有效利用途径,发现煤矸石可以用来制备建筑用砖、混凝土,还可以从中提取Al2 O3、 Fe2 O3,制备硫酸铝铁( PAFS)、白炭黑、分子筛以及无机纤维等化工产品,实现煤矸石高附加值利用的目的。

The coal gangue dangers situation was analyzed and found that the coal accumulation can contaminate soil, trigger dust storms, take up valuable land resources, further make destruction of the ecological landscape, at the same time can also lead to the occurrence of geological hazards. To achieve recycling use of coal gangue, many people have committed to explore an effective utilization way to find out that coal gangue can be used in the preparation of brick and concrete construction, and also extract Al2 O3 , Fe2 O3 , manufacturing aluminium sulfate iron ( PAFS ) , white carbon black, molecular sieve, and inorganic fiber and other chemical products, to achieve the purpose of high value-added utilization.
