The Buddy Proximity Detection System was designed to train operators,
helpers and visitors to stay a safe distance away from Continuous Miners.

Nautilus Coal-Buddy (MSHA Accepted)

This proximity detection system was designed and manufactured to train operators, helpers and visitors to stay a safe distance away from Continuous Miners. It is being used every day in production in ‘gassy’ Massey Energy and ICG (International Coal Group) mines in the USA.

The average installation time for a complete Coal Buddy System is one midnight shift.

Two very small, intrinsically safe MF4 Antennas are installed on the CM and they radiate two magnetic fields around the complete Continuous Miner (CM). The strengths of these magnetic fields are measured by the operator’s Proximity Detection Device (PDD) and if the operator is too close to the CM his PDD will warn him.

If the operator gets dangerously close to the CM (inside the Red-Zone) then the PDD will automatically disable the CM.
