In continuous mining, a machine known as a continuous miner cuts the coal from the mining face and deposits it directly into a haulage vehicle; an efficient technique that obviates the need for drilling and blasting. Room-and-pillar mining in low seams is generally less efficient than longwall mining because as much as 50% of coal is lost.
Equipment Armoured Face Conveyor (Face Coal Haulage) Once the coal is cut, it has to be removed from the face to the maingate, so some form of coal haulage system is required.
