摘　　要：由于盐类矿物的动态溶解特性受多因素的影响与控制,难以实施有效的控制溶解。本次室内试验模拟现场采矿方法,对水的流速、溶蚀面积对盐矿溶解特性的影响进行了研究。研究发现:无水芒硝矿溶解速度与溶蚀面积成指数关系,溶解速度与溶腔内溶液流速的关系为,在一定范围内,岩盐溶解速度随流速的增大而增大,当流速达到一定值后,溶速不再增加,甚至下降。Because of multi-factors influences and control on dynamic dissolving characteristic of salt deposit, it is hard to efficiently implement controlling solution for salt deposit. So, the influences of velocity of flow and solution acreage on salt dissolving character are studied in this experiment. Through study, it is found that the relation between dissolving speed of Glauber`s salt deposit and solution acreage On the other hand, it is found that the relation between dissolving speed and velocity of flow in cavity is as follows: in a range of zero to a fixed value, the higher the velocity of flow, the higher dissolving speed, when the velocity reaches the fixed value, dissolving speed of rock salt is no longer increased, but is decreased.
