In this paper, the acid wastewater pollution caused by the closed pit of xiayuanqiaotou Coal Mine is taken as an example. Through hydrogeological survey and field inspection, the geological and hydrogeological conditions of the study area are understood, and the cause and discharge of acid wastewater pollution in the mining area are analyzed. The results show that the goaf and coal gangue leaching water formed by the disorderly mining of small coal kilns in the Yudonghe Vally are the main sources of acidic wastewater pollution, and direct drainage from the mine mouth is the main drainage method of pollution in the Yudong Vally.Based on this, the technology of source control plus terminal treatment has been adopted, and applying regional water treatment and prevention technology to treatment is a new model of both specimens and treatments.which will play a significant role in the treatment of acid mine water in Guizhou and the south in the future.
