Abstract: The accurate positioning of the coal mine personnel and equipment is a major factor for coal mine production safety protection.The Coal Mine mobile targeting is basically to take the regional positioning mode,but can not finish the underground continuous monitoring and positioning.Combination of WiFi technology and GIS geographic information technology,modern communications technology,computer technology,WiFi-based wireless sensing network,to achieve continuous dynamic positioning downhole moving target,and the perception of the miners ambient information,real-time perception of location information ambient information fusion and geospatial location based geographic information technology,mine the actual figure of surveying and mapping results positioning and locomotive location query target historical trajectory and playback on electronic mine map,dynamic real-time location of coal mine moving target effectively,all of which will improve mine safety production levels and reasonable allocation of resources.
