| 摘 要： | 本实验的目的是为了查明察尔汗盐湖首采区卤水开来过程中固体钾矿层溶解的可能性。我们采用该区外围钻孔晶间卤水（Ⅰ１０，Ⅰ１３，Ⅱ２，Ⅴ１０，Ⅴ１２，Ⅴ１６，Ⅸ１孔）进行了溶解光卤石实验，从结果可看出其卤水中钾含量明显增加，从５．７５—１５．６０ｇ／Ｌ增至２４．１５—３０．００ｇ／Ｌ。这说明了在卤水开采过程中下伏固体钾矿层可以被溶解，进一步增加该区晶间卤水中的ＫＣｌ储量。在我们实际观测过程中曾发现某些地带晶间卤水钾含量极度增高，应是此因素所引起的。

| Abstract: | The purpose of the experiment will find out the possibility of resolving potash ore layers for intercrystal brines in the first exploiting area of Qarhan Salt Lake during the process of brine exploitation. We adopted the intercrystal brines in surrounding drillholes (Ⅰ10, Ⅰ13, Ⅱ2,Ⅴ10, Ⅴ12, Ⅴ16, Ⅸ1 )of this area to carry out the experiment of resolving carnallites. The result shows that the potassium content in those brines obviously increased from 5. 75-15.60g/L to 24.15-30.00g/L. It illustrates that the underlying potash ore layers can be dissolved dur-ing the process of brine exploitation and the KCl reserves in the intercrystal brines increase further. In fact,the appearance of some extrame high-potassium belts observed in the inter-cerystal brines should result from that factor. |
