دانلود کتاب Recommendations for Evaluating and Implementing Proximity Warning Systems on Surface Mining Equipment

Compiled by the U.S. Dept of Health and Human Services, CDC/NIOSH Office of Mine Safety and Health Research, this 2007 publication provides guidance on effective proximity warning technology in the mining industry, installation and maintenance considerations, along with recommendations for effective implementation. Accidents involving surface mining equipment are partially attributed to the lack of full visibility and this report presents plots of blind areas for five pieces of surface mining equipment. Several technologies designed for detecting obstacles in blind areas and providing a warning to the operator were evaluated on off-highway dump trucks. These proximity warning systems included radar, sonar, GPS, radio transceiver tags, and combinations of radar and cameras. This study found several commercially available systems that could effectively warn an equipment operator of an impending collision and show promise for reducing accidents. In most applications, it is recommended that sensor-based systems be combined with video cameras to provide important alarming functions along with an actual view of the blind area.
