Protective structures for low-coal shuttle-car operator. Report of Investigations/1987
This paper describes Bureau of Mines efforts to develop partial protective structures for operators of low coal shuttle cars. In coal seams 48 in. high or less, full-coverage canopies are generallyExpand
Novel design for a thin seam shuttle car featuring an ergonomic operator compartment
Since 1982, the US Bureau of Mines has investigated improvements in protection for operators of thin seam shuttle cars. Due to working height restrictions in thin seam mines {le}1.22 m or 48 in.,Expand
Flywheel-powered shuttle car. Report of Investigations/1991
The report describes the development, system-by-system evaluation, and preliminary surface testing of a flywheel-powered shuttle car. The use of a self-contained flywheel power source has theExpand
