Status and development trend of mine positioning technology

Common mine positioning technologies were analyzed from aspects of positioning methods and wireless communication technologies, and application of the mine positioning technologies in personnel positioning system and equipment proximity detection were described. It was pointed out that future mine positioning system or equipment would comprehensively utilize technologies such as wireless ultrahigh frequency ranging, inertial navigation, multi-source hybrid positioning and multi-source information fusion to form a positioning service system oriented service, so as to realize accurate positioning of underground personnel and equipment, proximity detection of large mobile device and personnel, and autonomous navigation and positioning of mining equipment and underground rescue personnel (robot).
