Firstly, this paper provides the overall structural design of the mine safety auxiliary system of Wireless Sensor Networks, and introduces various types of module node which consist of the system. This paper also highlights the advantages of Wireless Sensor Networks technology which can form Ad Hoc Network and data Multi-hop. Finally, it puts forward the RSSI ranging algorithm. According to the actual condition in the mine environment, the original formula can be simplified. The experimental results show that in the range of 100m testing, the relative error 3.044% can be achieved, which can fully satisfy the requirements of the mine personnel positioning.
