Centro de Documentacion de Fundación MAPFRE - Acceptable workloads for three common mining materials

Notes: Sumario: A series of psychophysical lifting studies was conducted to stablish maximun acceptable weights of lift for three supply items commonly handled in underground coal mines (rock dust bags, ventilation stopping blocks, and crib blocks). Effects of lifting in four postures (standing, stooping under a 1-5 m ceiling, stooping under a 1-2 m ceiling, kneeling) were investigated together with four lifting conditions. The results suggest thar miners are often required to lift supplies that are substantially heavier than psychophysical acceptable lifting limitsRelated records: En: Ergonomics. - London and Washington. - Vol. 35, nº 9, September 1992 ; p. 1013-1031Materia / lugar / evento: Ergonomía Biomecánica Columna vertebral Antropometría Condiciones de trabajo Diseño del trabajo Minas de carbón Otros autores: Hamrick, Christopher A.
