However, ever since the introduction of continuous miners in the late 1940s, room-and-pillar continuous mining has been gaining ground over conventional room-and-pillar mining. In recent years, room-and-pillar continuous mining accounts for more than 38 percent of the underground coal production ( EIA, 2017 ).


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 …
