西北矿区供水现状及矿井水综合利用研究

Study of Mine Water Comprehensive Utilization and Current Situation of Northwest Mining Area Water Supply

我国西北地区煤炭资源丰富但水资源缺乏,对煤矿开采产生的矿井水进行综合利用具有重要意义。通过收集西北36个矿井设计报告,调研新疆神新公司和宁夏宁煤集团,分析计算得出西北矿区煤矿生产吨煤供水量平均为0.261m3,矿井吨煤涌水量为0.54m3,平均矿井吨煤涌水量是生产供水量的2倍以上;而即使在我国西北地区各矿井供水全部采用矿井水的情况下,预计仅可以利用矿井涌水总量的42.2%。因此建议,为了提高我国西北地区矿井水的利用率,亟需出台相关矿井水资源利用的优惠政策,协调煤矿对外供水,大力推进矿井水产业化综合利用。

Abundant coal resources and lack of water resources in northwest China,mine water comprehensive utilized has an important significant,which generated form coal mine mining. All Mine design reports of 36 coal mine in northwest were collected,after investigate and survey in Xinjiang Shenxin company and Ningxia Ning coal group,then an average water supply for unit coal mining was about 0. 261m^3 for coal mine in northwest,water inflow about 0. 54m^3 for unit coal mining,an average water inflow of unit coal mining was more than 2 times to water supply amount,so under the situation that water supply all used mine water in all coal mine in northwest China,and it could only reached about 42. 2% to total mine water inflow,so in order to improve mine water use ratio in northwest China,some related preferential policies for mine water resources utilized should be introduced,external water supply should be harmonized,and mine water industrialization comprehensive utilization should be improved greatly.
