摘要
为研究项目区的水文地质条件特征,对项目区开展全面的水文地质条件调查,并进行水文地质钻孔、抽水试验和包气带饱和渗透等现场试验工作。综合得出项目区地下水类型主要为第四系孔隙潜水及基岩裂隙水;区内地下水补、径、排条件稳定。包气带厚度较大且分布连续稳定,防污性能中等,地下水不太容易受到污染。露天采坑涌水会造成局部含水层疏干,但附近无居民且无其他取用地下水用户,采矿活动对地下水环境影响较小。
In order to study the characteristics of hydrogeological conditions in the project area, carry out a comprehensive survey of hydrogeological conditions in the place, and carry out field tests such as hydrogeological drilling, pumping tests, saturated permeability of the vadose zone. It is concluded that the groundwater types in the area are mainly quaternary pore phreatic water and bedrock fissure water;the groundwater supplement, runoff, and discharge conditions in the area are stable. The vadose zone has a large thickness and a continuous and stable distribution, with moderate antifouling performance, and groundwater is not easily polluted. Water gushing from an open pit will cause local aquifers to be drained, but there are no residents nearby and no other groundwater users. Mining has little impact on the groundwater environment.
