Coal Mining and Processing Energy Trends Insider

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. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is

3 Technologies in Exploration, Mining, and Processing

In underground mining the mining machine (if mining is continuous) can be used as a sound source, and receivers can be placed in arrays just behind the working face. For drilling and blasting operations, either on the surface or underground, blast pulses can be used to interrogate rock adjacent to the rock being moved.
HighTech Mining Makes Coal King of Fossil Fuels, But Is It Clean?

Sep 30, 2009 Longwall Mining About 33 percent of all underground coal production in the U.S. comes from longwall mining. A continuous mining machine is used to isolate huge rectangular panels that are extracted by an automated shearer moving back and forth along the face. Here's how it all works. Erin McCarthy.
