Abstract
Placing an operator of a mobile continuous haulage conveying system under a protective canopy was investigated using the latest technology for both canopies and floating compartments. Investigations first considered how to position the operator in the low compartments and included unobtrusive observation of human subjects repositioning themselves when confined to the compartment. Locations for such a compartment on the crawler-mounted machine were considered using both small-scale and full-scale mockups. A floating operator compartment was designed in conjunction with the new design for an improved machine. Evaluation of the compartment for human factors was made at the manufacturer's facility prior to installing the machine in an underground coal mine. Subjects representing the male 5th, 50th, and 95th percentile sizes were used along with photographic techniques for recording data. Operation of the new machine with operator compartment in a coal mine with seam heights typically between 40 and 46 in was monitored for 10 months. The practical feasibility of this operator protection was adequately demonstrated for coal seams as low as 40 in.
