Mining coal Coal miners use large machines to remove coal from the earth Many US coal deposits, called coal beds or seams, are near the earth's surface, but others are deep undergroundModern mining methods allow US coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in Banksman or banker A banksman, banker, hillman or browman works at the pit bank to dispatch the coals, and organise the workforce He is in charge of loading or unloading the cage, drawing full tubs from the cages and replacing them with empty ones [1] The counterpart role at pit bottom is the onsetterGlossary of coal mining terminology

Drills are also used to prepare an area for blasting In coal mining, drills are used to create portals for workers to enter the mine Drilling Methods The type of drill selected depends on the drill method used which in turn depends largely on the type of material being minedVentilation control of dust in coal mines is important in the different types of underground coal mining such as (1) room and pillar mining, (2) longwall mining and (3) shaft mining Type (1) is done in an ore deposit where some of the ore is left behind to form columns in the mine that prevents it from collapsing and it is used for coal miningMine Ventilation Ventilation control of dust in coal mines GRT
