A psychophysical determination of ingress/egress dimensions for mobile underground mining equipment was performed. The study group consisted of 32 volunteers, 16 males and 16 females, mean age 33.4 years. Four males had prior experience working in underground coal mines and had entered or exited mobile underground mining equipment. The subjects donned full mining gear and entered and exited a mockup of a cab that had opening dimensions corresponding to seam heights of 81, 95, 123, 135, or 160 centimeters (cm). The openings were equipped with sliding doors. The subjects were instructed to adjust the width of the sliding door for each opening to the minimum which in their judgment would allow safe and comfortable ingress and egress. The mean opening widths selected for the 81, 95, 123, 135, and 160cm seam heights were 78, 98, 112, 122, and 132cm, respectively. The 95th percentile opening widths were 162, 149, 140, 122, and 101cm, respectively. The authors conclude that the data indicate that as the seam height becomes lower, a larger opening is needed for miners to safely and comfortably get in and out of mobile underground mining equipment. These data should be useful for engineers designing mobile underground mining equipment.
