| 摘 要： | 2013年进行的疏干开采抽水试验揭示罗布泊罗北凹地钾盐矿区现阶段深部承压储卤层(W1、W2、W3)水文地质参数为附近区域zk0601在2006年详勘时的十余倍。为了确认这种现象在罗布泊盐湖是否具有普遍性,2016年在罗北凹地钾盐矿区选择LBSK1、LBSK2两个区域开展水文地质参数验证研究工作。验证研究表明,2006年至今罗北凹地钾盐矿区承压储水层水文参数的确有普遍增大的现象。分析认为,矿区钾盐开发过程中大规模抽取地下卤水引起的卤水运动加速、储卤层水—盐动态平衡被破坏,从而导致深部承压储卤层水化学成分、地质结构发生变化,这些变化是导致上述现象的重要原因。对上述现象的分析研究将为矿区下一步采输卤工程设计提供重要的水文参数,对今后矿区储量管理以及生产计划安排具有指导意义。

| Abstract: | The large-scale extraction of underground brine for seven years has resulted in acceleration of the groundwater movement in Lop Nur potash mine area and destruction of the dynamic equilibrium of brine-salt in confined aquifer. Diagenesis such as salt precipitation or dissolution may occur, leading to some changes of the brine chemical composition, geological structure and hydrological parameters in confined aquifer. Through geological drilling and pumping test of the atypical block in the Luobei mining area, the hydrogeological parameters of the underground confined aquifer are obtained. The preliminary conclusion was got by comparing with the relevant hydrogeological parameters in the same area and analyzing of reasons for the parameters change. And the hydrological parameters, got from the LBSK deep dredging pumping test near the drill of zk0601 in 2014, were verified. The research results are of important guiding significance to the management of mine reserves, the design of brine extraction and transportation engineering, and the production planning management of the reserves, and the management of waste brine and the production plan for our company. |
