The reliability and survivability of conventional communications systems in harsh mining environments has always been a problem. The extreme conditions such as falling rock, collapsing tunnels, fires, explosions and flooding, during which communications are needed most, can also render them inoperable. An emergency underground communication system needs to be very robust with respect to these and other potential hazards. This paper deals with wireless backbone positioning for mesh wireless local area (WLAN) network. The routing problem is simulated to define the best position to place the wireless access point in mine galleries. The optimization strategy applied to the network design problem is the genetic algorithm. From various criteria such as the power profile through the mining gallery and the average SNIR level, the genetic algorithm treats all the possible positions and determines the optimal one for an effective communication. Optimization results considering density effect and other parameters such as the range, the hop number, the received power variation, the connection quality between access points are present
    • "In the Val d'Or mine, Canada, experiments gave fruitful results regarding mesh wireless local area network (WLAN) using WAP (Wireless Access Point) protocol [28]. 2006 Miner Act by MSHA: According to this, the installation of two-way wireless voice and tracking systems for all underground coal mines in US has been made compulsory.

    [Show abstract] [Hide abstract] ABSTRACT: This paper presents an overview of wireless communication systems for underground mines including voice and data communication. Development of Wired , semi – wireless and wireless communication systems are also discussed. Application of various wireless communication systems in underground mines of USA, Australia, Canada, South Africa, European countries etc including indigenous experimental trials were illustrated. In this paper a brief review is given on the advanced communication systems adopted in various mines with a bird's eye view on the basic researches made in 1970-2000. Recent devices such as SIAMnet, TeleMag, PED, and VDV leaky feeder systems are discussed which provide voice, video and Mobile Data Communication at very high speed data with wireless applications. Impetus is given for urgent application of recent technologies on wireless communication in view of various disasters due to lack of communication in mines.

    [Show abstract] [Hide abstract] ABSTRACT: The underground communication in tunnels and mines is very challenging due to the hostile nature of the environments and to the propagation issues that electromagnetic waves suffer there. Communication is often unidirectional (e.g. in mines) or very costly (e.g. leaky feeder in road tunnels) and hard to install and maintain. This work proposes the use of multi-hop ad-hoc networks to provide multimedia communication between mobile nodes in such a hostile environments, relying on a complete hardware/software, cheap and easy-to-setup platform that can be used both as temporary or fixed infrastructure or as communication backbone in emergency scenarios like mine accidents or a tunnel collapse. The communication is based on the Real-Time Multi-hop Protocol (RT-WMP) and its QoS extension executed over several nodes equipped with specific hardware. This protocol manages delay sensitive messages and the node mobility across the network while the QoS extension is responsible for allowing the end-to-end voice communication. The specific topology and situation have driven to a specialization of RT-WMP to better perform in this type of environments, taking advantage of the a priori (partial) knowledge about the topology. This proposal was tested in a real application in the Somport tunnel, the about 8 km-long railroad linking Canfranc, Spain with Pau, France.

  • [Show abstract] [Hide abstract] ABSTRACT: After a recent series of unfortunate underground mining disasters, the vital importance of communications for underground mining is underlined one more time. Establishing reliable communication is a very difficult task for underground mining due to the extreme environmental conditions. Until now, no single communication system exists which can solve all of the problems and difficulties encountered in underground mine communications. However, combining research with previous experiences might help existing systems improve, if not completely solve all of the problems. In this survey, underground mine communication is investigated. Major issues which underground mine communication systems must take into account are discussed. Communication types, methods, and their significance are presented.
