Critical Appraisal of Coal Gangue and Activated Coal Gangue for Sustainable Engineering Applications
Applied SciencesCoal gangue, a primary solid waste by-product of coal mining and processing, constitutes approximately 10–15% of total coal output. Its accumulation poses substantial environmental challenges, including land occupation, spontaneous combustion, acid mine drainage, and heavy metal leaching. Despite its high silica and alumina content (typically exceeding

Recognition Methods for Coal and Coal Gangue Based on Deep Learning [PDF]
IEEE Access, 2021 Recognizing coal and coal gangue is an important part of the coal industry and is mainly conducted via human sorting at present. Consequently, considerable manpower is needed, which adds a burden to enterprises and results in low efficiency. As an important branch of artificial intelligence, deep learning has been widely applied in many fields ...
