英文摘要：

Mine safety has become an important issue to be solved in intelligent mining research. Aiming at practical problems of network poor robustness and the wireless emergency facilities incomplete in mine safety monitoring system, the basic framework and function of the wireless sensor networks is analyzed, and the hybrid network topology structure of wireless and wire, and the perception of the nodes diamond deployment method which ensured the network coverage and connectivity are put forward. Then, network communication protocol and composite transmission technology have been researched, and the project implementation concrete plan of being suitable for mine wireless sensor network was proposed. To some degree,it promoted the mine safety monitoring network performance.
