Advancement of Cab and Canopy Design and Use in Coal Mines.
NTIS: PB/86-153574 :306 pages
The use of protective canopies can result in canopy roofing and/or serious restrictions to operator comfort and vision. To document this experience, a field study was conducted of cab and canopy design and application that resulted in a catalog of 164 canopy designs. An analysis of field data showed no simple relationship between working height and canopy-related problems. The relationship also involves (1) machine frame height, (2) mine floor undulations, (3) operator compartment dimensions, and (4) canopy design and location on the machine. Data analysis indicates (1) present technology does not always permit successful application of canopies in working heights below 42 inches and (2) development of satisfactory low-coal canopies is doubtful. The basic conclusion of the study is that future research and development studies should be directed at development of alternative protection systems and remote mining methods.
