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

    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.

    ABSTRACT: This paper presents statistical and experimental analyses of narrow-band wave propagation at 2.4 GHz in an underground gallery. The aim of this study is to address the deployment issues associated with wireless communication systems of Wi-Fi wireless access points and their coverage. A genetic algorithm is used to produce all the numerical results present in this paper. Four known statistical models based on different cumulative distribution functions are used to compare these results with those obtained from experimentally. The models are applied to two different galleries in an underground area. Two performance evaluation criteria, the mean square error (MSE) and the Kolmogorov-Smirnov test, are used to comparatively assess models' efficiency. These are the MSE and the Kolmogorov-Smirnov test.

    ABSTRACT: The IEEE 802.15.4/ZigBee standard is considered as a potential candidate for wireless sensor and actuators networks. Several commercial platforms with IEEE 802.15.4/ZigBee support have been made available in the last few years, and an increasing number of operating systems specifically designed for sensor and actuator networks are evolving. Underground mining is considered to be one of most hazardous industrial activity. The industrial automation applications in the mining galleries can benefit from the recent technological advances. In fact, many approaches to reduce costs and improve performance have been examined. The main objective of this paper is the implementation and evaluation of wireless sensor networks for environmental data measurements in a real underground mine. Therefore, the nodes were evaluated in real operating conditions.
