A series of psychophysical lifting studies was conducted to establish maximum acceptable weights of lift (mawl) for three supply items commonly handled in underground coal mines (rock dust bags, ventilation stopping blocks, and crib blocks). Each study utilized 12 subjects, all of whom had considerable experience working in underground coal mines. Effects of lifting in four postures (standing, stooping under a 1.5-M ceiling, stooping under a 1.2-M ceiling, and kneeling) were investigated together with four lifting conditions (combination of lifting symmetry and lifting height).
