峰峰煤田矿井水资源利用经济效益评价

Evaluation of Economic Benefit of Mine Water Resource Utilization in Fengfeng Coal Field

峰峰煤田矿井排水量大,大量矿井排水不仅造成水资源的严重浪费,而且污染环境,另一方面,该区工农业用水又十分紧缺。据统计,峰峰煤田13个煤矿现状总排水量为10690.85×104m3/年,进一步开发利用的潜力较大。通过现状排水量和未来10年、20年排水量利用的经济效益评价,矿井污水经过处理以后用于工业和居民生活效益较好,就地利用比异地利用的经济效益好。

There is a massive drainage in Fengfeng coal field, which not only causes the serious waste of water resources, but also environmental pollution. On the other hand, the industrial and agricultural water supply shortage is very serious in the area. According to statistics, Fengfeng coal field, which includes 13 coal mines, has a total drainage of 24933.15 × 10^4m^3/a at present, the potential exploitation and utilization is large. According to the utilization evaluation of economic benefit of actual drainage at the present and next 10 years, 20 years, the mine sewage will have great benefit to industry and residents living after been purified, and onsite utilization has better economic benefit.
