| Resumen |
Hand scaling is a physically-demanding task responsible for numerous overexertion injuries in underground mining. It requires the miner to use a long pry bar to remove loose rock, reducing the likelihood of rock fall injuries. The experiments described in this article simulated "rib" scaling (scaling a mine wall) from an elevated bucket to examine force generation and electromyographic responses using two types of scaling bars (steel and fiberglass-reinforced aluminum) at five target heights ranging from floor level to 176 cm. Ten male and six female subjects were tested in separate experiments. Peak and average force applied at the scaling bar tip and normalized electromyography of the left and right pairs of the deltoid and erectores spinae muscles were obtained. Findings are discussed. |
