Abstract  The underground solution mining of salt cavern energy storage is hard to observe or control. Therefore, a solution mining model is needed for the design, prediction and control of the cavern development, to make sure the final cavern shape meets the long-term stability requirements. The progress was concluded about the solution mining mechanism and modeling method, including the salt dissolution rate, brine convection model, collapse of the insoluble interlayers, and sedimentation of the insoluble substances. The main problems and development tendency was pointed out for the salt cavern modeling and design.
