摘　　要：在收集、分析察尔汗盐湖大规模采卤过程中水化学变化相关数据和固、液矿转化试验基础上,建立描绘采卤过程中水化学变化规律的数学模型,对采卤过程中卤水化学成分进行模拟预测,结果表明,由于存在化学组分由固相到液相的转化,只要地下水有补充,在一定的期限内,卤水中的钾浓度均能达到开采品位,控制卤水开采速度,可以使该地区的钾最大限度的开采利用。In this paper, the model to simulate the chemical composition changes at the process of exploiting brine in Chaerhan Salt Lake area had be established based on observing data of large-seale multi-year process collected and analysis of the transformation test between solid mineral and brine. The forecast of the changes of chemical composition of brine in the exploit course of brine had got by use of the mathematical model. The simulation results show that the concentration of potassium in the brine can reach the mining grade because of migrate of the chemical component from solid mineral to brine. The maximize development and utilization of potassium can be done by control mining rate of brine as long as the ground water have anything to add to a certain period of time.
