RCT has released its RCT Connect, a WiFi network for underground mining machine automation and control operations such as remote diagnostics and live machine tracking. RCT Connect uses a coaxial cable to transfer power and information from machines to access points as distant as 1.5 kilometres, reducing the number of cables and configuration required for WiFi connection, according to the company. The network can “operate a mobile machine in a particular work area underground to perform a specific task such as loading and dumping, haulage, secondary breakage or rock breaking over a grizzly,” explained Brendon Cullen, product manager of automation and control at RCT. “Depending on the communications systems, these machines can be operated remotely or autonomously from underground, the surface or, if required, off-site.” RCT says the Connect is compatible with all types of automated machines.
