Underground Coal Mining Method
Underground coal mining is the process of extracting coal from the earth through underground mines. Tunneling technology has advanced to a point where it is economical for many coal companies to mine some of their reserves by underground mining methods.
Coal that is extracted from underground mines is commonly referred to as “room and pillar” mining. In this type of mining, access tunnels are driven into a coal deposit, which are then filled with a room and pillar system. This system consists of pillars and archways that support the roof of the tunnel and are used to hold up the coal. The coal is then mined in a series of rooms of the tunnel, and the removed coal is moved to the surface in conveyor buckets and muck cars.
Another method of underground coal mining is longwall mining. This method uses specialized machines to slice layers of coal from the underground wall using a rotating drum. The cut coal is then moved via a conveyor system to the surface, where it is moved to the surface in conveyor buckets and muck cars.
Regardless of what method is used for Underground Coal Mining, safety measures are of the utmost importance. Companies that operate underground mines need to adhere to safety regulations and develop programs to keep miners and equipment safe. Additionally, companies must monitor air quality to ensure there are no hazardous levels of toxic dust.
In addition to safety concerns, underground coal mining presents a number of environmental challenges. Underground mines can result in subsidence, which is when the ground above the mine cave in, leading to land and environmental damage. Additionally, underground mines may result in the release of contaminated water and hazardous dust if ventilation systems are not properly managed.
Underground coal mining is a complicated and dangerous process. Despite the challenges, it is often the best and most economical way to extract coal from a coal deposit. By using advanced mining methods and strict safety protocols, mining companies can ensure that underground coal mining is conducted safely and efficiently.
