From: NIOSH Mining Safety and Health
MSHA recently announced a proposed rule requiring that continuous mining machines be equipped with proximity detection systems. NIOSH has been working on this problem for over ten years and believes that an Intelligent Proximity Detection (IPD) system may be the answer to keeping miners safe around underground equipment. Continuous mining machines, the initial target of the rule, present one of the biggest challenges to safety because of the number of workers close to the machine and the variety of ways the machine can move, pivot and tram.
