MALVERN, PA — In a significant technological leap forward for the mining industry, Rajant Corporation has joined forces with Crossover Distribution, Sonim Technologies, and Mutualink to introduce a groundbreaking communication solution designed to enhance safety and efficiency in underground mining operations. The collaboration was detailed in a case study centered around a successful proof of concept at the NORCAT Underground Centre in Sudbury, Ontario, Canada, showcasing a blend of digital voice and high-speed data capabilities at the mining forefront.
Traditionally, underground mining operations have relied on the ‘Leaky Feeder’ radiating cable network for communication. This antiquated system, primarily facilitating basic two-way radio voice communications, falls short in addressing the critical need for communication at the working face of the mine—the hub of production activities. Recognizing this gap, the collaborative effort led by Rajant Corporation aims to revolutionize mine communication, ensuring seamless connectivity even in the most extreme environments.
Darin Gibbons, Executive Vice President of Crossover, highlighted the synergy between Rajant and its partners, emphasizing the successful integration of VHF to VoIP phone crossbanding technology. This innovation allows workers to switch effortlessly between using a phone or a radio for communication, supported by both legacy systems and Rajant’s advanced Kinetic Mesh® network.
The core of this novel solution lies in Rajant’s Kinetic Mesh BreadCrumbs®, small, portable network nodes that extend coverage deep into the mine’s working face, past the limitations of the leaky feeder system. Coupled with the Mutualink GO KIT installed on the surface and connected to Rajant’s wireless network, and a VHF radio bridging the gap to the traditional leaky feeder system, the solution facilitates robust communication. Miners can now use Sonim smartphones equipped with push-to-talk functionality to communicate seamlessly from the mine face to colleagues wielding portable VHF radios.
This technological breakthrough is not just about enhancing communication; it’s a stride toward significantly improving underground mining safety, efficiency, and productivity. By enabling real-time, reliable communication at the working face, miners can swiftly address hazards, coordinate operations more effectively, and ensure a continuous flow of information between the surface and the depths of the mine.
Darrell Gillis, Rajant Sales Director – Canada and a lifelong participant in the mining industry, brings a personal perspective to the initiative, underscoring the transformative impact of this solution on mining communications. From his family’s longstanding involvement in Canadian mining, Gillis understands firsthand the challenges posed by inadequate communication systems and the potential of Rajant’s solution to overcome these hurdles.
As the mining industry continues to evolve, the partnership between Rajant, Crossover Distribution, Sonim Technologies, and Mutualink sets a new standard for innovation in underground communication. This advancement promises not only to safeguard the lives of miners but also to streamline operations, marking a significant milestone in the journey toward more technologically advanced, efficient, and safe mining practices.
