Noise Assessment of Stone/Aggregate Mines: Six
Mining consists of bench drilling and blasting (by a contractor), and mining the limestone rock.The blasted rock is mined using front-end loaders (FELs) loading into 45.4-, 49.9- or 54.4-t- (50-, 55- or 60-st-) capacity haul trucks for removal from the pit. The haul trucks dump into a primary crusher located near the pit entrance.
