Abstract: In view of coal mine production operation environment and disaster risk factors in the process of mining, based on ZigBee technology and the information fusion of coal mine safety monitoring system.By building a wireless sensor network based on ZigBee protocol, implementation of downhole environmental data collection, transmission, and then via the industrial Ethernet will collect data sent to the monitoring center computer.According to the requirements of system data fusion, is proposed in this paper, based on fuzzy closeness and two levels of data fusion model of grey correlation degree, level data fusion using fuzzy closeness algorithm to extract the environment parameter feature vector.Secondary data fusion by using grey correlation algorithm to fusion of feature vector again, accurately determine the safety status of coal mine, coal mine safety level decision-making is given.
