Coal Gangue Comprehensive Utilization Project of Baishan City
Coal Gangue Comprehensive Utilization Project of Baishan City. . 1. Introduction to the Project. Coal gangue is a kind of solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with low carbon content and harder than coal, which is associated with coal seam in the process of coal achieved a series of research results in underground coal and gangue washing and backfill mining (Zhang et al. 2020a, b; Zhang et al. 2018). Moving screen jigging, air pulsating jigging, and heavy medium shallow tank wash-ing are the main coal and gangue washing technologies used in underground coal mines at present.
