罗南湖盆钾盐矿区水文地质特征及地下水系统分析

Hydrogeological Characteristics and Groundwater System Analysis of Potassium Salt Mining Area in Luonan Lake Basin

罗布泊盐湖位于新疆塔里木盆地东部,自1995年在罗布泊罗北凹地发现超大型钾盐矿床以来,罗布泊盐湖地质科学研究与资源调查进入了一个新阶段。为了提升罗南湖盆钾盐矿区地下水害的防治能力,减少矿区水害事故发生,将矿区的水文地质环境条件、地下水系统以及补给条件进行勘查,以便更好的预测矿井涌水量,防止矿井水害的发生。本文根据罗南湖盆钾盐矿区水文地质调查情况,就矿区水文地质特征、地下水系统补给和涌水量进行了勘查分析,以期为矿区钾盐开采提供一定的安全保障。

Lop Nur Salt Lake is located in the eastern Tarim Basin, Xinjiang. Since the discovery of super-large potassium deposits in the north depression of Lop Nur in 1995, the geological research and resource investigation of Lop Nur Salt Lake have entered a new stage. In order to enhance the prevention and control ability of groundwater hazards in the potash mine area of Luonan Lake Basin and reduce the occurrence of water hazards in the mine area, the hydrogeological environment conditions, groundwater system and recharge conditions of the mine area are investigated in order to better predict the mine water inflow and prevent the occurrence of mine water hazards. Based on the hydrogeological survey of the potassium salt mining area in the Luonan Lake Basin, the hydrogeological characteristics of the mining area, the recharge of groundwater system and the amount of water inflow are investigated and analyzed in order to provide certain security for potassium salt mining in the mining area.
