Application Status and Development of Coal-based Solid Waste Filling Mining Technology
Under the background of carbon peaking and carbon neutrality goals,accelerate the construction of green mines is the key to realize the transformation and upgrading of China's mining industry and green development,and to build a new pattern of mining industry.Coal-based solid waste filling mining technology is an important part of the green mining system.It can not only absorb coal gangue,fly ash,desulfurization gypsum and other coal-based solid waste on a large scale,but also effectively avoid a series of ecological and environmental problems such as surface subsidence,groundwater loss and gas discharge.The main types of filling mining were summarized,and the advantages of six typical coal-based solid wastes as filling materials were analyzed.The technical principles,process characteristics and future research focus of four kinds of coal-based solid waste filling mining methods,namely,fully-mechanized solid filling,fully-mechanized paste filling,fluid slurry pipeline filling and overlying rock grouting technology,were focused on,laying a theoretical foundation for the realization of green mining,clean utilization and zero waste discharge of coal resources.
