Abstract: The development way, deployment and architecture of current underground mobile applications are not unified, and the transmission method between ground server and the applications is various, it makes multiple professional applications on a mobile terminal cannot share data and cannot be unified login, and forms a new mobile information island. To solve above problems, a construction idea and solution of underground mobile application system platform was put forward combining with coal mine application scenarios and special environment. The system platform adopts design ideas of shared libraries and modular application, and achieves standard development mode of underground mobile application, so as to solve the problems of data sharing, automatic deployment and rapid development of the underground mobile application.
