罗布泊罗北凹地液体钾盐矿(W2、W3、W4)承压卤水开采工艺探讨

在罗北凹地液体钾盐矿区深部承压含水层水文地质参数缺乏的情况下,充分利用现有矿区地下水监测数据及矿区水文地质资料的基础上,根据正在运行的采卤生产井做抽水试验得到深部承压含水层单位涌水量、影响半径、渗透系数等水文数据,与前人在罗北凹地钾盐矿区不同水文地质区域做过的抽水试验取得的水文数据进行对比并加以验证,以此确定罗北凹地液体钾盐矿区相对难开采的深部承压含水层卤水的开采方式及采卤工程的布置工作。

Discussion on brine mining technology with confined brine of liquid potash mine (W2, W3, W4) in Luobei depression, Lop Nur

In the absence of hydrogeological parameters of the deep confined aquifer in the liquid potash mining area,Luobei depression.On the basis of making full use of existing groundwater monitoring data and hydrogeological data of mining area.The data of the unit water inflow,influence radius,permeability coefficient and other hydrological are obtained by pumping test of the running bittern production well,which are compared and verified with the hydrological data obtained from the previous pumping tests in different hydrogeological areas of the potash mining area in Luobei depression.In this way,the mining method of brine in deep confined aquifer and the layout of brine mining project are determined.
