河南省某煤矿用水项目取用水合理性分析

Analysis of the Rationality of Water Withdrawal for a Coal Mine Water Project in Henan Province

【目的】项目区位于丘陵地带,城市供水管网未覆盖,矿区生产及生活仅可以利用处理后达标的矿井涌水。为分析煤矿生产及生活取用水的合理性、矿井涌水可供水量及取水水源的可靠性,促进水资源优化配置和用水结构的调整,实现水资源高效利用和科学管理,开展本次研究。【方法】采用比拟法成功预测了矿井涌水量,分析矿井涌水可利用量,开展项目用水水平分析。【结果】通过预测与分析得出,项目总用水量为797.85 m^(3)/d(29.12万m^(3)/a),矿井正常涌水量为886.5 m^(3)/d(36.94 m^(3)/h)。【结论】矿井涌水量可以满足用水需求,且水质达标,项目取用水是可靠的。

[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 m^(3)/d(291200 m^(3)/a),and the normal mine water inflow is 886.5 m^(3)/d(36.94 m^(3)/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.
