Telecontrol is a technology providing significant safety improvements in mining by relocating machine operators hundreds of meters away from the immediate health and safety hazards. The US Bureau of Mines recently developed and patented a telecontrol system for underground room-and pillar mining. This system features near-to-time closed-loop control. A demonstration system was constructed that can be used in thin-seam applications down to 914 mm. Details are provided on the developed telecontrol system, with the emphasis placed on the programmable-logic-controller-based electronic control system.
