Abstract: In this paper, it designed hidden dangers, illegal information acquisition system in the process of coal mine safety production management. By taking handheld devices as the hardware carrier, and J2EE as the platform architecture technology, it carried out hidden dangers and illegal flow processing platform design, and formed the network information system of fixed-mobiled convergence. It could finish real-time acquisition of underground coal mine hidden danger and illegal information, and achieve integrated safety supervision of the ground and underground in coal mine.
