Increasing Mine-Car Coal Bulk Density by Vibration. Final Report

摘要

The ultimate objective was to increase mine car payloads by compacting the coal via vibration. Conceptual design studies included a state-of-the-art investigation and bench scale laboratory vibration testing and bench scale distributive type loading (as opposed to point type loading) testing. England and Germany employed vibration methods, with a measure of success, to increase payloads but have since discontinued its use. Distributive loading is an untried method of increasing bulk density which the laboratory tests indicate could produce a 10 to 15% increase in bulk density. Laboratory tests indicate that using both systems would not produce additive results. Further research into distributive loading was recommended.
