Abstract: Based on the convenient operation environment and powerful application range of WeChat program, a simple and practical analysis platform for dehydration technology of fine tailings is developed.Through the combination of WeChat program front-end interface and back-end storage server, The designer only needs to input basic parameters as prompted, then the calculations can be completed quickly.The applicability of the dehydration technology calculation platform is verified by a practical project case.The results show that the calculation results of the platform are accurate and the time consuming is very short.As a fast calculation platform, it has far-reaching significance for the design of tailings and the field application.
