新疆哈密大南湖二矿水资源现状分析

Analysis of water resource status in Da'nan Hami Xinjiang

为了解新疆哈密大南湖二矿生态修复过程中可用水量,通过实地调查,收集和分析煤矿区水资源相关基础资料,明确矿区可用于生态修复的绿化用水量和水质,为矿区的生态修复提供理论依据。结果表明:(1)矿区生产、生活用水分别以矿坑涌水和榆树沟水库地表水为供水水源;(2)2016年~2018年矿区总用水量为183.68×10^4m^3,生产用水占81%,绿化用自来水量占5%。(3)矿区的生活污水、生产废水处理站的中水分别用于矿区绿化和地面冲洗及道路洒水。(4)矿区目前绿化面积约6.11×10^4m^2,绿化用水量约为12.90×10^4m^3/a,中水水质符合绿化用水标准。

In order to understand the amount of water available during the ecological restoration process of the Danan Lake No.2 mine in Hami,Xinjiang,through field investigations,the basic data related to water resources in the coal mine area was collected and analyzed to clarify the greening water consumption and water quality that can be used for ecological restoration in the mine,and to provide a theory for ecological restoration in accordance with.The results show that:(1)The production and domestic water in the mining area are taken from the pit gushing water and the surface water of the Yushugou Reservoir as the water supply sources;(2)The total water consumption in the mining area from 2016 to 2018 is 183.68×10^4m^3,with production water accounting for 81%,greening the amount of tap water accounts for 5%.(3)The domestic sewage in the mining area and the reclaimed water from the production wastewater treatment station are used for greening and ground washing in the mining area and road watering respectively.(4)The current greening area of the mining area is about 6.11×10^4m^2,and the water consumption for greening is about 12.90×10^4m^3/a.The quality of the intermediate water meets the greening water standard.
