Coal gangue has become one of the industrial wastes with the largest annual discharge and accumulated stock in China. The disorderly accumulation of coal gangue not only occupies a large amount of land resources and causes natural disasters, but also pollutes the surrounding ecological environment, which in turn affects human health and normal production and life. In this paper, the physical, chemical and pollution characteristics of coal gangue are summarized, and the ecological restoration mode is divided into two modes: traditional “end treatment” and “treatment while piling”. The action mechanism, advantages and disadvantages and application scope of various ecological restoration technologies involved in the two modes are listed, compared and analyzed, which provides scientific reference for the restoration and treatment of other similar geological environments.
