Continuous Miners - Coal Education

Continuous Miners. A machine with a large rotating steel drum equipped with tungsten carbide teeth that scrape coal from the seam. Operating in a “room and pillar” system – where the mine is divided into a series of 20-to-30 foot “rooms” or work areas cut into the coalbed – it can mine as much as five tons of coal a minute – more than a miner of the 1920s would produce in an ...

Continuous Mining - Coal Leader

Continuous miners operate a room and pillar mining system. A series of 18 to 20 foot wide rooms are driven in the coalbed with pillars or columns of coal left standing to help support the roof. Roof bolts, typically four to six feet long steel bolts, are inserted into holes bored into the roof to bind the strata together support the roof.
