Coal Mining And Processing. Coal is mined by two methods: surface or 'opencast' mining or underground or 'deep' mining. Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground.

GRT: Activate Underground Coal Mining and Processing

2020-8-17 · The challenges they face underground and above ground differ, although the challenge has a commonality how to best manage coal dust. In underground mining water is sprayed in order to prevent spark arrest, however performs quite badly in its secondary role as a dust suppressant. As it is conveyed, crushed, and eventually stockpiled, again water is typically used to wet the coal enough to prevent dust
