Abstract

Abstract

The massive accumulation of coal gangue not only pollutes the surrounding environment but also constitutes a waste of the resource itself. The pathways and current research status of coal gangue in soil utilization and as soil amendment agents are systematically reviewed, including direct land application of coal gangue, improvement of soil with mixtures of coal gangue, soil, organic matter, fungi, and solid waste, as well as the production of fertilizers or the preparation of porous ecological soil from modified coal gangue. Additionally, the use of modified coal gangue mixed with exogenous materials to cultivate seedling substrates, fertilizers, and artificial soils is discussed. There has been some progress in utilizing coal gangue for soil utilization and as soil amendment agents in China, but the control of heavy metals in coal gangue should also be paid attention to enable its large-scale consumption as much as possible. Finally, the paper identifies existing issues in the use of coal gangue for soil utilization and soil amendment agents, and provides corresponding suggestions to serve as a reference for related research.
