摘要
我国西北新疆地区气候干旱,三塘湖矿区多年平均降水量为41.6mm,年均蒸发量2273.7mm,降水量远小于蒸发量,地表水资源匮乏,水资源成了当地工业项目决策的重要条件.通过断面法计算该区新近系地下水的补给量为13826 m3/d,采用体积法计算地下水储存量为4.03×108m3,运用解析法非稳定流计算20a允许开采量为33163m3/d.这些参数,为该区将来大规模开发和清洁利用煤炭资源提供了基础依据.
Abstract
The climate in the Xinjiang area,northwestern China is arid.Mean annual precipitation in the Santanghu mining area is 41.6mm;mean annual evaporation is 2273.7mm,far higher than precipitation.It caused lack of surface water resources,thus a major issue in local industrial project decision.The cross section method estimated Neogene groundwater recharge is 13826m3/d,volumetric method estimated ground water reserve is 4.03 × 108m3,through analytic method unsteady flow estimated 20 years allowable exploitation yield is 33163m3/d.All of the numbers have provided the basis to large-scale exploitation and clean utilization of coal resources in the area aftertime.
