CDC - Mining Project - Open Pit Highwall Safety - NIOSH

Oct 01, 2020  This pilot project research addresses two issues that are fundamental to open pit highwall mining: rockfall catchment and slope monitoring. Rockfall hazards in open pit mines are a constant threat to mine workers and are typically addressed by catch benches—horizontal spaces set in from the highwall to retain rock spillage—as mandated by the Mine Safety and Health Administration (MSHA).
