The Pennsylvania Mining Complex, located in Greene and Washington counties, is the largest underground coal mine complex in North America. Consisting of the Bailey, Enlow Fork and Harvey mines, along with the central preparation plant and train loadout facility, it is among the safest and most productive complexes in the world.
Opencast mining involves scraping at the ground's surface, while room and pillar mining occurs below ground. Likewise, longwall mining uses heavy machinery to dig at coal seams beneath the surface. Click through the interactive infographic to learn more about the different processes involved with coal mining.

The processes can remove only 30 to 60 percent of the pyrites, however, because some pyrites are not broken free of the coal and are present in a given piece in a quantity too small to increase its weight enough to be rejected. Coal Mining Equipment

Coal mines generally extract coal which is classified as a rock rather than a mineral. A mineral is considered to be a naturally ocurring substance with a definite chemical content. Coal has a variable chemical content. As for mining processes, they are quite variable. The most productive underground method is known as longwall.
What are the Different Coal Mining Processes? By: / Various machines are used in coal mining. The different processes used in coal mining are employed depending on the location of the coal, whether it is located close to the surface or underground.
"The Bill undermines rigorous and thorough approvals processes at both state and Commonwealth level with which all major mining projects must comply. Banning coal mining in the Galilee Basin will do nothing to reduce emissions."
The days of deep coal mining may be largely gone for the UK, but smallscale, varied mines are ensuring the industry's survival. In this interactive map, we spotlight some of these sustaining projects, including lithium mining in Cornwall, tin mining in Devon and gold mining in the Highlands.

A set of simulation models was developed with the help of this simulation system. These models were developed with the goal to be used as a quality assurance tool for new process control systems of coal mining. Simulation models of various subsystems of coal mining were united to create simulation environment of coal mining.
The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
