The layer of solid KCl is so thin in depth、so small in size、 and so low in grade that it is too difficult to exploite it. Besides that, only 1/3 of the liquid KCl can be expoi ted due to the mining method of well and canal drainage which is being used now. Therefore, it is one of the key problems to exploite the liquid KCl as possible as we can and to turn the solid KCl into explo itable liquid deposit in Qarhan salt lake. So the idea of dissolving and driving exploitation has been suggested. This paper will deal with three problems as follow

然而由于固相矿层薄、品位低而难以直接开采利用，加之目前对液相矿产只是纯疏干性开采，充其量只能采出1/3的液相矿，因此如何最大限度地开采液相矿产，同时将固相矿产转化成能直接开采利用的液相矿产是察尔汗盐湖开采中急需解决的关键问题之一，对此人们提出溶矿驱动开采的设想，本文正是以此为目的，着重研究以下三个问题
