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 (=1.22 m or 48 in.). Federal mine regulations require that canopy protection on shuttle cars be provided only in mines =1.07 m (42 in.). However, court obtained variances are granted to mines =1 .22 m (48 in). This paper presents ongoing research to design and evaluate a uniquely positioned, ergonomic compartment for a shuttle car that provides the operator with full canopy protection in working heights of 1.02 m (40 in.).
