Surface testing and evaluation of the hopper-feeder-bolter. Information Circular/1988

Technical Report ·
OSTI ID:7059942
The Hopper-Feeder-Bolter (HFB) is a prototype multifunctional machine designed to improve productivity by minimizing continuous-miner place changes. It is designed primarily to work beside a two-pass continuous miner, bolting on one side and then place changing to bolt the other side while simultaneously providing a surge car and lump breaker located directly behind the continuous miner. Surface testing was conducted at the Bureau of Mines Mine Equipment Test Facility to evaluate overall system performance and reliability. Tests were conducted to evaluate place changing, tramming, lump breaking, roof bolting, drawbar pull, coveying, temporary roof-support capacity, lighting, and noise. Surface-test results indicate the HFB is ready to be tested and evaluated underground in a production mode.
