Machines Used in Coal Mining | Career Trend

 · For extracting coal which lies close the surface, huge dragline shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for until the coal is removed, at which point the the dirt ...

Appendix E: Coal Mining and Processing Methods | Coal ...

Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flatlying, thick, and uniform coal beds. A highpowered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floorlevel conveyor system ( Figure ).

From Shovels to Machines

At first, machines helped miners load more coal; eventually, they put the majority of miners out of work. Beginning in the late 1940s, coal companies rapidly introduced longwall and continuous mining machines. Longwall machines sheer coal from the face in a circular motion. The broken coal falls into a pan line, which leads to a conveyor belt and then to the processing plant. Longwall machines ...

Mine

Coal stored at a wash plant is loaded onto coal trains through large hoppers, however in smaller mines machines such as front end loaders can be used to load the coal. Some smaller mines may also determine it is more feasible to transport coal by trucks to the closest railway loading facility as opposed to funding an expansion directly to the mine.
