NIOSH OMSHR has been actively developing electromagnetic proximity detection technology since the 1990s, with several systems commercialised and now in use. The MSHA-approved systems detect the presence of personnel and stop machine functions when incursion into the red zone occurs. NIOSH OMSHR has advanced proximity detection technology to become "intelligent", ie able to determine a worker's position relative to the machine and selectively disable machine functions. By only disengaging specific machine motions that could be hazardous, iPD is designed to allow miners to move around the CMM more freely. This has the potential to improve safety by allowing the miners to better avoid other hazards, such as unsupported roof and other pieces of equipment. In addition, the operators can stand nearer the machine to see visual cues necessary for safe and efficient operation. These benefits have the potential to improve acceptance by underground workers while maintaining safety and protection from striking and pinning accidents.
