摘要：Coal gangue is one of China's main industrial solid wastes,which contains various harmful heavy metal elements,such as lead(Pb).The long-term accumulation of coal gangue causes Pb to migrate to the surrounding environment due to weather-ing and rain erosion,eventually endangering human life and health with its continuous accumulation in the food chain.This review discusses the migration and transformation process of Pb in coal gangue under different conditions and summarizes the available forms and mechanisms of Pb in coal gangue.The current prevention and control and comprehensive utilization methods of Pb in coal gangue are comprehensively reviewed,and the characteristics of each method are discussed.In order to realize the economical,efficient,and high resource utilization of coal gangue,this paper provides favorable suggestions and support for subsequent in-depth research and the implementation of heavy metal prevention and control measures.
