OSTI ID:7295066
The objective of this contract was to develop protective canopy concepts for low coal machines. The four machines specifically addressed in this study were the Wilcox Mark 20 PJ Auger Miner, the Wilcox Roof Bolter ('J'), the Lee-Norse 245L Continuous Miner, and the Elkhorn AR-4 Scoop. Protective canopy concepts were designed for each machine. Wooden mockups of the canopy concepts were constructed. These mockups were installed on the machines and were evaluated in the mine by the machine operators and mine foreman. (GRA)
