Study on The Optimal Development Planning of Western Mining Area Based on WEAP Water Resources Model
The shortage of water resources seriously affects the sustainable development of coal mining in western mining areas.In order to guide the formulation of the development plan of the mining area from the perspective of water resources,so as to maximize the comprehensive benefits of the western mining area.Taking a mining area in the west as an example,according to the possible development direction of the mining area,the four factors of population growth,mining scale,water saving intensity and greening intensity were comprehensively considered to formulate 8 contingency plans for the development of mines until 2035 in terms of the data from 2015.By using the WEAP model,the changes in water demand,water deficit,and water deficit rate in mining areas under different contingency plans were simulated.Based on the simulation results,multi-objective functions of the mining,including the economic,social and ecological environment were established,and the optimal plan was finally selected.The results show that the plan to maximize the comprehensive benefit value of the mining area is the plan of"strong mining,strong water saving and moderate greening",and the comprehensive evaluation value is 0.6856.Taking this plan as a reference for the mining area to formulate the next development plan,the water resources carrying capacity of the mining area has been improved,and the comprehensive benefits of the mining area have been maximized.
