Longwall mining is one of the most common coal mining techniques used in deep underground mines. The machine is basically a series of coal shears mounted on a hydraulic ceiling mount that moves independently of computer instructions.

Long wall miners are usually about 240 meters wide and between 1.5 and 3 meters high. They removed large blocks of coal, called panels, which can be up to 3,650 meters long.
Coal is cut from the face of the wall with large shears and loaded onto conveyor belts that move it. As longwall mines move past the panels, they collapse the roof structure behind them when they are no longer needed.
Spoons are large, wide vehicles that can run on batteries or diesel. They are used to scoop coal and other waste from areas that are no longer needed. Typically operated by a single miner, they have a flattened and reduced profile that allows them to be used in mines where face can be significantly restricted.
A sustainable miner is a machine that extracts coal from coal seams. This includes a large rotating drum equipped with extremely hard carbide teeth. They can mine more than three tons of coal every minute.
This engine requires almost no distributor or spark plugs. Operation is quite simple as no ignition adjustment is required. It is important to replace the oil filter, air filter and fuel filter regularly with these engine parts for efficient operation.
