Design, fabrication, and testing of a hopper-feeder-bolter. Open File Report (Final), September 1977-December 1986

Technical Report ·
OSTI ID:7134412
This report documents the design, fabrication, testing, and coal-mine demonstration of a hopper-feeder-bolter during a four-phase program for the U.S. Bureau of Mines. The machine was designed to increase productivity and safety in underground room-and-pillar mining. It performed well as a hopper-feeder for continuous haulage during a coal-mine demonstration. Testing in a simulated mine showed that the machine also has good roof-bolting capability.
