The Xiaojihan Coal Mine Mine Water Treatment Project belongs to Shaanxi Huadian Yuheng Coal – Electricity Co., Ltd. This project is of great significance as it aims to address the long – term water shortage in the desert areas of northern Shaanxi and the water pollution in the affiliated mining area. The project was completed in two phases and is the largest and most – invested mine water comprehensive utilization demonstration project in Shaanxi Province. With an investment of approximately $60 million, the mine water pretreatment capacity reaches 1900 cubic meters per hour.
