陕北浅埋煤层开采地下水影响分析及保护对策

Northern Shaanxi shallow seam mining groundwater impact analysis and protection countermeasures

我国陕北地区子长矿区一带煤层薄、埋藏浅,煤炭开采形成塌陷区后将会形成导水裂隙带导通上层含水层,特别是导通区内具有供水意义含水层,致使区内村庄饮用井泉水位下降,甚至疏干,严重时会使受影响村庄居民没水吃。通过区内典型浅埋煤层开采地下水影响分析,计算出地下水影响的程度和范围,据此有针对性的提出矿区地下水资源保护措施,以保护区内地下水资源,保障煤矿区居民饮水安全。

In the Zichang mine of China's northern Shaanxi Province,thin coal seam and shallow burial,after formation of coal mining subsidence area,it will be formed tge upper aquifer conducted by the water seamm,especially,there is a water supply significance aquifer in the conduction area,which resulting in level of the drinking water well in the villages of the district declining even drought.At the moment of serious situation,it will cause to no water to drink.Through analysis on the typical shallow seam mining groundwater,it calculates the extent and scope of the impact of groundwater and puts forward some protection measure of groundwater resources in the mine so that to protect groundwater resources and ensure safety of the drinking water for the livings this area.
