Development and assessment of new and existing canopy technology to lower coal seams

Book ·
OSTI ID:7182318
The goal of this investigation was to increase safety in low-seam underground coal mines through development and in-mine evaluation of a temporary roof support system for roof drills and floor-riding operator compartments for a loader and shuttle car. During phase I, state-of-the art canopy technology was investigated, and preliminary design a mock-up evaluations were performed for temporary roof supports, single- and dual-boom bolters, and for transverse-mounted floor-riding canopies for a shuttle car and load loading machine. The shuttle car and loader canopies were approved for further development, and the design, fabrication, testing, and certification were completed in phase II. In phase III, the Bureau of Mines furnished a shuttle car for use in the evaluation of the canopy for 45 shifts. The shuttle car canopy was evaluated at the Virginia Crews Coal Co. in West Virginia. Efforts to secure an evaluation site for the loader canopy were unsuccessful.
