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
