【摘要】 在简要介绍室内静态试验结果和单矿柱、多矿柱试验方法的基础上,讨论了原地晶间卤水、异地晶间卤水和淡化尾液的单矿柱溶解驱动试验结果,证明原地晶间卤水和异地晶间卤水基本没有溶矿能力,淡化尾液的试验结果表明溶解驱动过程在时间上分为4个阶段,即溶解驱动前阶段、光卤石阶段、钾石盐阶段和石盐阶段,其中光卤石阶段和钾石盐阶段是溶解驱动固体钾矿的主要阶段。最后对溶解驱动开采固体钾矿的必要性及溶解驱动规律的特点进行了讨论。更多还原

【Abstract】 After a brief introduction of static dissolving results and method of the single ore-pillar and the multi-orepillar experiments, this paper focuses on the discussion of dissolving-driving results of single ore-pillar laboratory experiments using 3 types of solvents which are the in situ inter-crystal brine,the foreign inter-crystal brine and the freshening milltailings.It is proved that the in situ inter-crystal brine and the foreign inter-crystal brine have very low capacity to dissolving solid potash deposit. The dissolving-driving process of freshening milltailings can be divided into 4 periods in time,that is the pre-dissolving-driving period,the carnallite period,the sylvite period and the halite period successively.The carnallite period and the sylvite period are the main periods of dissolving-driving solid potash deposit.At the end of the paper,some characteristics of the dissolving-driving process are discussed.更多还原
