Because of the diversity of classification in mobile software development platform,each platform is not compatible with each other.The developer must spend a lot of time in modification,transplantation and maintenance of software.This paper proposes an application development program of cross platform (one time code,multiple deployment),by using the Hybrid App which combines the advantages of Web App and Native App.It has the characteristics such as Web Storage function,cross platform,etc.The program is used in the mine monitoring system development.In addition,it can ensure the security of user information,for encrypting the user password.These managers of mine can check the internal operating enviornment at any time,anywhere through the app monitor.It also realizes real-time monitoring effectively and reduces the occurrence of accidents in mine.
