【摘要】 通过实验及计算分析得出难溶性钙芒硝盐岩溶解完全后的孔隙率以及一些溶解特性。利用溶解效果的计算得出钙芒硝盐岩在静态溶解条件下,溶解17天后能基本溶解完全。在钙芒硝溶解完全的情况下, 初步研究发现如果钙芒硝矿纯度高,其溶解后有35．87％的孔隙率,这为难溶性钙芒硝矿继续溶解提供了充足的溶解通道;否则,由于钙芒硝盐岩和泥岩膨胀率的不同,导致钙芒硝盐岩溶解完全后完全散开。溶解后孔隙率的研究对难溶性钙芒硝盐岩水溶开采机理的研究有重要的意义。更多还原

【Abstract】 The glauberite is a kind of difficult solubility salt rock, after it dissolve complete, by the tests, we get it’s voidage and some other dissolution characteristic. Through the calculation of dissolution effect, we know the glauberite to dissolve in static state, after 17 days it will completely dissolve. Under the condition of complete dissolve, preliminary study show that if the glauberite quality are high, the voidage is 35.87%,that provide enough voidage for the difficult solubility glauberite to go on dissolving; otherwise ,it will disperse and not any solid framework. This is important to study on solution mining mechanism of the difficult solubility glauberite.更多还原
