Analysis of Radio Communication Networks in Underground Mining for Emergencies

In this paper we analyzed the reliability of radio communication system for underground mine. In general, reliable operation of the network depends on many factors and overall network consists of a large number of components. We proposed the proposal how to use Dijkstra's algorithm to improve the reliability of the radio communication. In this study, we analysed factors that influence of the underground mine reliance. We used the Oyu Tolgoi underground mining radio communications system for this article and this underground mine currently has three main exits, two of which are intended for human access and one for ventilation purposes only. The radio communications devices in underground mines are connected by optical and radiation cables and these cables are installed in all cross-section areas. The radio communication plays a vital role in providing safety of underground mines. However, it is not the easiest one to provide reliability of radio communication in underground mine. In the event of underground mine incidents, there is an urgent need to track the location of mineworkers and evacuate them as soon as possible. In case of emergencies (a fire, an earthquake etc.) in underground mines, it is very crucial to provide reliable radio communication system and to evacuate workers within short period. The results of the paper show that how to set an optimal route to move to the place where the radio communication is available during the accident in the region of the underground mine.
