Abstract
In recent years, with the large-scale exploitation and utilization of coal resources in China, ecological and environmental issues in coal mining areas have become increasingly prominent. As typical surface subsidence water-accumulating landforms, coal mining subsidence ponds have sediment with dual functions of a pollutant “sink” and a potential “source”, playing a pivotal role in ecological restoration and environmental remediation in mining areas. Currently, the sediment in coal mining subsidence ponds is characterized by complex composition, high pollution load, and highly variable physicochemical properties, posing significant challenges for precise analysis and effective management. Therefore, this study systematically summarizes the relevant research progress from the perspectives of the variation characteristics of physicochemical properties, trace elements, and environmental risks of the sediment in coal mining subsidence ponds, aiming to provide a scientific basis for the precise assessment and restoration of the ecological environment in subsidence areas.
