为更深入的了解钙芒硝盐岩的溶解特性，促进水溶开采钙芒硝矿和盐穴储气库建造中钙芒硝夹层溶蚀的研究，对钙芒硝盐样以不同倾角在35℃恒温水中进行溶解速率和速度的实验。结果表明：钙芒硝在35℃恒温水中溶解速率和速度具有角度效应；倾角从90°～－90°变化时，溶解速率和速度越来越大，水溶采矿技术开采钙芒硝时应采用有利于上溶和侧溶，自下而上的开采技术；运用MATLAB对数据进行拟合，得出不同溶解角度下钙芒硝溶解速率和速度随时间变化规律的表达式，对水溶开采钙芒硝的相关研究和盐穴储气库夹层的溶蚀具有一定的指导和参考价值。

In order to understand deeply dissolution characteristic of glauberite salt rock, and promote glauberite ore mining by water-solution and research to corrosion of glauberite interlayer in building salt cavern gas storage, dissolution rate and velocity of glauberite were studied by different angels in 35 degrees thermostatic water.The re-sults show that dissolution rate and velocity of glauberite are related to angles, and their values become bigger and bigger along with angles change from 90 to -90 degrees, therefore glauberite solution mining should adopt mining technique from bottom to top in favor of the upper and side solution.The expressions describing dissolution rate and velocity of glauberite along with angels and time change are obtained by using MATLAB to fit data, which have a certain guidance and reference value to solution mining glauberite ore and corrosion of glauberite interlayer in build-ing salt cavern gas storage.
