"Rich coal, lack of fat, less gas" energy structure determines the demand and supply of coal in the foundation position in China's energy for a long time are hard to change. At present, in China coal energy production and consumption once were in a percentage of more than 70%. China's coal production mainly comes from underground mining, because coal resources special production environment, the underground work risk factors is higher, often happen gas explosion accidents, floods, make the country suffered great economic losses in the underground staff at the same time life security threats. In the production process to realize intelligent monitoring and management, can effectively improve the production safety accidents occurred in underground can timely and accurate acknowledge underground work personnel's location information is the important guarantee of successful rescue.
This topic is the purpose of presenting the design of a mine safety monitoring system, realize the environmental monitoring and personnel downhole positioning function. Based on the comprehensive monitoring system at home and abroad, mine coal mine first discusses the current situation of the development of the safety monitoring system, comparison of the remote monitoring and control system used for communications technology, this system design choice a more superior communication mode, then briefly introduces ZigBee wireless sensor technology, analyzes the comprehensive monitoring system for coal mine, this paper puts forward a kind of ZigBee technology based on the comprehensive monitoring system solutions mine, the paper describes the overall structure of the system and the system structure, the design of based on ZigBee wireless network nodes and AD7705 chips based on the data acquisition system.绝对不是机器，
