PowerTrunk, part of the Sepura Group, announced that Agnico Eagle Mines significantly expanded its TETRA radio communications network, including the addition of specialized data applications, at its Meliadine gold project near Rankin Inlet, Nunavut, Canada.U.S. ITC to Begin Investigation into Motorola’s Complaint Against Hytera

Agnico Eagle recently announced that its Meliadine gold project, located in the low Arctic of Northern Canada, received approval from its board of directors to proceed with construction. The project has now shifted into full development mode, and the additional personnel and activity will mean an increase in communications traffic and security procedures that need to be applied.
“While initially a single-site PowerTrunk-T infrastructure, the TETRA network at Meliadine has grown to add hot-standby redundancy, a total of five site base stations and an additional mast-mounted base station for rapid deployable operations or for use in specific areas during construction and operation,” said David Torres, senior vice president of sales, PowerTrunk.
The mine also extended TETRA coverage to include its underground operations over a standard UHF leaky feeder system. By mid-2017, Agnico expects to have about 500 radios in use, and every light and heavy equipment vehicle will have an IP67-rated mobile radio installed.
Mining operations will also add GPS tracking and two custom-built short data applications (SDA) to run on digital portable radios for blast notice and for stench gas release request.
“The unique ability of TETRA to support both voice and enhanced data applications on the same user device has given us the opportunity to add two custom applications that enhance our safety procedures,“ said Philip Quessy, Agnico’s IT general supervisor for Nunavut.
The blast notice application will help secure the communications and increase awareness of upcoming blasts in the mine. Although announcements are still made via a voice call, the SDA is designed so that when it is triggered, a blast notification will appear in all selected terminals displaying when and where the blast is taking place and who has authorized it.
The second custom application is designed to allow a terminal user to request a stench gas release. A stench gas release sends a clear and definitive odor throughout the underground operations in the event of an emergency, indicating the initiation of emergency response procedures. By having the application accessible to the appropriate personnel through their radio devices, at anytime there is a severe accident that requires emergency response procedures, anyone on the surface or underground could potentially release that gas into the ventilation system to therefore trigger evacuation or other emergency procedures.
