Abstract Coal mine acidic mine water has the characteristics of strong acidity and high concentration of heavy metals, which has caused serious harm to the coal industry and ecological environment. This paper summarizes the causes of acid mine water, expounds the active treatment technology and passive treatment technology, analyzes the advantages and disadvantages of each treatment technology, and looks forward to the future development direction.
