| 摘 要： | 为探究补水背景下大盐滩矿区潜卤水水化学组分的变化规律,采用水化学分析测试方法,对2015年5月和7月分别就矿区33口长期观测孔内潜卤水中的Ca~(2+)、K~+、Na~+、Mg~(2+)、HCO_3~-、SO_4~(2-)、Cl~-的含量进行测定,分析矿区潜卤水中Ca~(2+)、K~+、Na~+、Mg~(2+)、SO_4~(2-)、Cl~-的变化趋势,并查明其分布特征。结果表明:补水背景下,大盐滩矿区潜水含水层中的潜卤水水化学组分在时间和空间上存在着明显的变化。在时间上,5~7月时间段内,K~+,Na~+、Mg~(2+)、SO_4~(2-)的浓度升高,且Na~+浓度变化幅度较大;Ca~(2+)、Cl~-浓度降低。在空间上,矿区中部和东南部,晶间潜卤水中的K~+、Mg~(2+)、SO_4~(2-)浓度较高;矿区北部晶间潜卤水中的K~+、Mg~(2+)、SO_4~(2-)的浓度则相对较低。补水可以适当地增大开采区域潜卤水中K~+的浓度,提升卤水的质量。

| Abstract: | Kunty salt lake is a secondary fault basin in northwest Qaidam basin. It contains very abundant brine resources. In order to explore the changing regularities of unconfined brine chemical components in Kunty mine with water supplement, this paper uses hydro-chemical analysis method to ascertain the changing regularities and distribution characteristics of Ca2 , K , Na , Mg2 , SO42-and Cl-. In May and July 2015, we collected brine samples in 33 observation wells and analyzed the concentration of Ca2 , K , Na , Mg2 , HCO3-, SO42- and Cl-in unconfined brine of Kunty mine. Based on the testing data, the results showed: With the continual water supplement, the hydro-chemical constituents in unconfined brine of Kunty mine showed a significant change in time and space. The concentrations of K , Na , Mg2 and SO42- increased while the concentrations of Ca2 and Cl- declined in May and July 2015. Na presented higher amplitude of concentration variation in time. The concentrations of K , Mg2 and SO42- in unconfined brine were much higher in the middle and southeast while much lower in the north of the mine. The water supplement could suitably enlarge the concentration of K and promote the quality of the unconfined brine in the Kunty mine. |
