Abstract
This paper details a task analysis conducted at three underground low-seam mines to evaluate their supply-handling systems to determine the physiological and psychophysical stresses of lifting in underground low-seam mines. Items were tracked from delivery to the surface storage areas to their final destinations underground. Of particular interest were those tasks that required manual handling of supplies or equipment. Analysis revealed that miners handle materials while on both knees a total of 58.3 pct of the time, 18.5 pct while stooped over, and 16.2 pct while kneeling on one knee. These working postures impose considerable stress on the lumbar spine and may be implicated in the high number of back injuries in underground mines. Videotapes made during this study became the basis for simulating lifting activities in controlled laboratory conditions.
