The project of "High Efficiency Utilization Technology and Demonstration of Mine Water in Large Coal Mines and Non ferrous Mines", led by Inner Mongolia Agricultural University, is jointly implemented by 10 units, including Nanjing University, China University of Mining and Technology (Beijing), China University of Geosciences (Beijing), Nanchang Hangkong University, China Institute of Water Resources and Hydropower Sciences, middling coal Shaanxi Yulin Energy and Chemical Co., Ltd., with a total investment of 59.93 million yuan, of which 19.3 million yuan is allocated by China, and the implementation period is three years. The project will be oriented towards green mining, with the goal of efficient utilization of large coal mine water in northern China and complex tungsten zinc polymetallic ore beneficiation wastewater in southern China. Following the overall approach of "basic research, technological research and development, integrated demonstration", the project will focus on solving the "changes in geological structure driven by coal mining and their induced hydrological system evolution and environmental ecological effects" Three major scientific issues, namely "Characteristics and Instability Mechanism of Water Solid Organic Colloidal Suspension System in Mine Water" and "Multi medium Interface Characteristics and Efficient Pollutant Removal Mechanism of Metal Mineral Processing Wastewater", focus on "Hydrological Evolution Mechanism and Geological Environmental Ecological Effects Driven by Coal Mining", "Coupling Simulation Technology of Coal Bed Water System Variation and Mine Water Quality under Different Mining Modes", "High Efficiency and Low Consumption Treatment Technology and Equipment for Coal Mine Water Classification" Research will be conducted on the new mode of coal water coordinated development and key technologies for efficient utilization of water resources, the classification and circulation of complex tungsten zinc polymetallic ore beneficiation wastewater and water-saving and pollution reduction technology, and the integrated demonstration of efficient utilization technology for well water in large coal mines and non-ferrous mines. It is planned to develop a batch of new modes and technical systems for efficient utilization of mine water and beneficiation wastewater, and to carry out mining in open-pit mines and underground mines Integrated demonstration of various large-scale coal mines such as tungsten zinc polymetallic mines and non-ferrous mining areas.
