U.S. Bureau of Mines research has addressed improved operator protection for thin-seam shuttle cars. Because of working height restrictions in thin-seam mines (<-1.22 M or 48 in), MSHA regulations require that canopy protection on shuttle cars be provided only in mines 1.07 M (42 in) and greater; however, variances are given to mines 1.22 M (48 in) and below. This paper reviews past Bureau efforts to develop protective structures for thin-seam shuttle car operators. The paper also discusses recent research leading to a novel method of protecting shuttle car operators, in mines as low as 1.02M (40 in), through the use of a cross-car, end-mounted operator compartment.
