Study on the Fragmentation Characteristics and Dust Generation Mechanism of Coal Cutting by Pick

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT During underground excavation, coal dust generation threatens miners' health and damages ecosystems. Its generation is directly influenced by cutting pick performance and inherent coal properties. This study investigates the effects of coal properties and cutting parameters on coal fragmentation characteristics from a mesoscopic perspective ...
