【摘要】：为确保煤矿区地下水资源的可持续利用,采用数值模拟方法研究煤层开采厚度变化对上覆松散含水层的影响。结果表明:对于新近系含水层,在采厚小于6m时,含水层未被疏干,在采厚为6,8,10和12m时,含水层均被疏干,疏干时间分别为300,270,150和120d;对于第四系含水层,在采厚小于10m时,含水层未被疏干,在采厚为10,12m时,含水层均被疏干,疏干时间分别为90,60d。研究成果为煤矿区松散含水层地下水资源保护提供依据。
[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.
