The precise object localization system is a fundamental infrastructure for the safe and effective production incoal mines. Authors analyzed the key problems faced by the localization of mobile objects in coal mines,such as road-way characteristics,excavation equipment,multipath features,multi-site interferences and error accumulations. The ma-instream methods of range measurement,including RSSI,TOA/TDOA and AOA/DOA,were summarized. The authorsalso discussed the com
