Longwall mining is a highly productive underground coal mining technique. Longwall mining machines consist of multiple coal shearers mounted on a series of self-advancing hydraulic ceiling supports. The entire process is mechanized. Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall.
The major drawback of surface mining is the method destroys large areas of land, demolishing landscape and natural habitat to recover coal. Is deep drilling worth the cost? While underground mining requires an array of resources, equipment and financial backing, the method is best suited if the environment and coal potential harmonize.

The shearer clearer system was designed, tested, and proven to be effective at lowering shearer operator dust exposures during the mid-80's by the U.S. Bureau of Mines. This technique uses a series of water sprays positioned on the shearer body and splitter-arms.
This system was upgraded during 2006 with the purchase of a new longwall equipment set. The shearer travels along the face at a speed approaching 40m/m, cutting 900mm of coal from the face at each pass. It typically completes 20–22 production cycles per shift, cutting at a rate of around 2,700t/h. Maximum daily (24-hour) output has been 46,340t.
Longwall mining has traditionally been a manual process in which alignment of the face equipment was done with string lines. Technologies have been developed which automates several aspects of the longwall mining operation, including a system that aligns the face of the retreating longwall panel perpendicularly to the gate-roads.
