Coal gangue as the largest solid waste of coal industry emissions,which will cause serious harm to social environment with improper handling. Scientific and rational exploit utilize of coal gangue had great significance in resource conservation,improving the environment,achieving sustainable development and so on. Expounded physical and chemical properties and hazards of coal gangue,at the same time,also discussed comprehensive utilization of coal gangue in building materials,land reclamation,subsidence filling,power generation and soil improvement. Combined with the development requirements and objectives of "coal industry thirteen five plan",proposed the future development trend of coal gangue depending on clean production and development of circular economy, and gradually established the coal-electricity-chemical-building materials,coal-coke-electricity-building materials and other modes of efficient recycling economy as well as green production chain.
