Analysis of the Rationality of Water Withdrawal for a Coal Mine Water Project in Henan Province
[Purposes]The project area is located in the hilly area,where the urban water supply network is not covered,and the production and living of the mining area can only use the mine water gushing after treatment.In order to analyze the rationality of water consumption in coal mine production and life,the available water supply and the reliability of water intake source,promote the optimal allocation of water resources and the adjustment of water structure,and realize the efficient use and scientific management of water resources,this study was carried out.[Methods]The comparison method is used to predict the mine water inflow,analyze the mine water inflow available amount,and carry out the project water level analysis.[Findings]Through prediction and analysis,it is concluded that the total water consumption of the project is 797.85 m3/d(291 200 m³/a),and the normal mine water inflow is 886.5 m3/d(36.94 m3/h).[Conclusions]The mine water inflow can meet the water demand and the water quality is up to standard,which improves that the project water withdrawal is reliable.
