西台吉乃尔盐湖矿区地下卤水组分区域分异特征

随着采卤活动的不断深入,西台吉乃尔盐湖矿区地下卤水的化学组分也逐渐产生了区域分异。根据化学组成随时间变化特征,矿区可划分为5个不同区域:西北孔隙卤水区、孔隙卤水和晶间卤水过渡区、降落漏斗核心区、降落漏斗周围区以及地表水影响区。研究表明,地表径流并未对矿区地下卤水产生明显影响,亦即现有的补水模式没有产生明显的作用。因此,有必要重新探讨补水模式,从而使得固体矿有效地向液体矿转变。

Characteristics of Regional Differentiation of Chemical Components in Underground Brine at Mining Area of West Taijinar Salt Lake

Along with the deeply mining at mining area of West Taijinar Salt Lake,the chemical components of underground brine has gradually engendered differentiation.In light to the characteristics of chemical components changes with time,the whole mining area is divided into five different sub-region:north-west pore brine area,transitional area of pore brine and intercrystalline brine,central area of cone of depression,margin area of cone of depression,and area influenced by surface water.The result shows that the surface runoffs do not bring the obvious influences to underground brine,namely,the model of supply of fresh water does not work effectively.Therefore,it is necessary to discuss the model that can produce the effective transmission from the solid deposit to liquid deposit.
