Some continuous miners can bolt and rock dust the face (two major components of servicing) while cutting coal, while a trained crew may be able to advance ventilation, to truly earn the "continuous" label. However, very few mines are able to achieve it. Most continuous mining machines in use in the US lack the ability to bolt and dust.
GENERAL DESCRIPTION Shortwall mining is one of the newest mining meth¬ods to be introduced into the world coal industry. The technique of shortwalling seems to have a number of origins, but it is generally agreed that it is an outgrowth of pillar-and-stall mining where timbering was employed as the primary means of roof support.

shift in 2006 (Niewiadomski, 2007). The vast majority of continuous miners are now operating with flooded bed scrubbers and taking extended cuts that are greater than 6 m (20 ft). An increase in the number of mines utilizing supersections (sections with two continuous miners) has also occurred.
The coal falls unto a conveyor belt and is transported to the conveyor system in the parallel shafts for its trip to the surface. This type of mining can make a 1/4 mile long cut (about 3-4 feet wide) in under one hour and can provide 4-10 times the amount of coal as a continuous miner.
Continuous miners. Though there are many variations in design, continuous miners mostly consist of five main elements: A central body to carry all other components mounted on some type of drive mechanism to provide mobility (most commonly tracks).

MC470 continuous miner is the ideal choice for room and pillar coal mines, salt and potash mines, and other operations that demand the highest cutting force. The miner effectively integrates proven technologies to offer high advance rates under tough mining conditions and in restricted spaces.
Continuous Miner Scrubber Effectiveness • MSHA approves use of deep cuts (roof, methane, dust control) −Mines must demonstrate effective control in standard cuts before MSHA considers approval of deep cut −Flooded-bed scrubber is a key component in deep cut dust control • Industry – Are deep cuts dustier than standard cuts?

Aug 20, 2019· Continuous miners are used to cut the coal and shuttle cars are used to transport the coal to a conveyor belt for further transportation to the surface. The pillars generated as part of this mining method can constitute up to 40% of the total coal in a seam. Higher seam recovery rates can be achieved if retreat mining is used.
The mine began production in August 1994. Employment is provided for 18 employees, 14 underground and four surface, on one production shift and one maintenance shift. The mine produces an average of 500 tons of coal daily from one continuous-mining- machine section. Coal is transported from the section to the surface via belt conveyor.
