Armored face conveyor’s smooth velocity control for increased durability
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2017, Vol 531, Issue 3
Abstract
The article presents the concept and assumptions concerning the smooth velocity control of an armored face conveyor, and also (on this basis) the subsequent transport conveyors used in an underground coal mine. The most-important significant mathematical equations are presented, allowing us to adjust scraper movement speed to maintain a constant cross section of the transported material stream, both in the case of unidirectional and bidirectional mining. Particular attention has been paid to the zones where a longwall shearer works with a variable web; that is, when a shearer is entering into a new coal seam layer at the ends of the excavation.
