水文地质参数是研究地下水运动的重要参数,抽水试验是获取水文地质有关参数的一种重要方法。本文以五彩湾矿区一号矿井地下水为研究对象,在分析区域水文地质条件资料的基础上,进行了7组单孔稳定流抽水试验。研究结果表明:对具有供水意义的第四系松散岩类孔隙含水层渗透系数为0.13~2.85 m/d,新近系碎屑岩类裂隙孔隙含水层渗透系数为0.07~0.316 m/d,白垩系碎屑岩类裂隙孔隙含水层渗透系数为0.02 m/d,侏罗系碎屑岩类裂隙孔隙含水层渗透系数为0.009~0.034 m/d。本次实验结果与对比收集资料结果完全一致。
Hydrogeological parameters are important parameters for studying groundwater movement. Pumping tests are an important method to obtain hydrogeological parameters. Based on the analysis of regional hydrogeological conditions, seven groups of single-hole steady flow pumping tests were conducted in this paper. The results show that the permeability coefficient of pore aquifer of Quaternary unconsolidated rocks with water supply is 0.13 ~ 2.85 m / d, the permeability coefficient of aquifer of clastic fissure of Neogene is 0.07 ~ 0.316 m / d, Cretaceous The permeability coefficient of clastic rock fissure aquifer is 0.02 m / d, and the permeability coefficient of fissure aquifer of clastic fissure in Jurassic is 0.009-0.034 m / d. The experimental results and the data collected by the results of the same.
