Abstract: Baiyanghe mining area is located in the oasis area on the northwest edge of Junggar basin in Xinjiang，The region's ecosystem is relatively fragile and sensitive，The natural forests and public welfare forests scattered along the Alamo River valley play a vital role in maintaining regional ecosystem security.Based on the prediction of the impact of coal mining subsidence in typical coal mines in the mining area,This paper focuses on the analysis of the impact of coal mining in mining areas on the groundwater system and ecosystem in the basin,puts forward some suggestions for optimizing and adjusting mining area planning,provides an important basis for government management to make decisions.
