Mining Publication: A Different Perspective: NIOSH Researchers Learn from CM Operator Responses to Proximity Detections Systems

• Continuous miners
• Proximity detection systems

Based on the results of several field performance tests, feedback from stakeholders and comments from continuous mining machine (CMM) operators throughout our interviews, NIOSH researchers have been working on the development of a more advanced version of proximity detection system (PDS) technology. They have recently created an intelligent proximity detection system (iPDS) using Mine Safety and Health Administration-approved electromagnetic proximity detection hardware. This technology contains efficient software that determines the real-time position of any worker relative to the CMM. The system then intelligently responds with visual signals and disables only machine motion that could cause striking or pinning - thus greatly reducing the frequency of false alarms. By blocking only dangerous machine functions while allowing other motions to continue, the iPDS would be less interruptive to the CMM operator's work. As a result, the incorporation of this technology into commercially available PDSs may lead to greater acceptance by the mining workforce while continuing to maintain the safety of mineworkers.
