【摘要】：為確保煤礦區(qū)地下水資源的可持續(xù)利用,采用數(shù)值模擬方法研究煤層開采厚度變化對上覆松散含水層的影響。結(jié)果表明:對于新近系含水層,在采厚小于6m時,含水層未被疏干,在采厚為6,8,10和12m時,含水層均被疏干,疏干時間分別為300,270,150和120d;對于第四系含水層,在采厚小于10m時,含水層未被疏干,在采厚為10,12m時,含水層均被疏干,疏干時間分別為90,60d。研究成果為煤礦區(qū)松散含水層地下水資源保護提供依據(jù)。
[Abstract]:In order to ensure the sustainable utilization of groundwater resources in coal mining area, the influence of coal seam mining thickness on overlying loose aquifer is studied by numerical simulation method. The results show that, for the Neogene aquifer, the aquifer is not drained when the mining thickness is less than 6 m, and when the mining thickness is 6 ~ 8 ~ 10 m and 12 m, the aquifer is drained for 300270150 d and 120 d, respectively, and for the Quaternary aquifer, when the mining thickness is less than 10 m, the aquifer is drained. The aquifer is not drained, and when the mining thickness is 10 ~ 12 m, the aquifer is drained, and the time of drainage is 90 ~ 60 days. The research results provide the basis for the protection of groundwater resources of loose aquifer in coal mine area.
