Mining of hard coal

isic code 051 covers the mining and extraction of hard coal, a vital energy resource that plays a crucial role in the global economy. Hard coal is a solid fossil fuel formed from the decomposition of ancient plant matter, and it remains an essential input for power generation, steel production, and various industrial processes. The mining of hard coal is a significant economic activity, providing employment and contributing to the energy security of many countries around the world.

The mining of hard coal typically involves a combination of surface mining and underground mining techniques. Surface mining, also known as open-pit mining, is used when the coal seam is located near the surface and can be accessed directly. Underground mining, or deep mining, is employed when the coal seam is buried deeper underground, requiring the excavation of shafts and tunnels to reach the resource. Both methods utilize specialized machinery, such as excavators, draglines, and continuous miners, to extract the coal from the earth.

The mining of hard coal requires several key inputs, including heavy machinery and equipment for extraction, transportation, and processing. This includes mining vehicles, such as haul trucks and loaders, as well as specialized drilling and cutting equipment. Additionally, the industry relies on a skilled workforce of miners, engineers, and technicians to operate the equipment and manage the mining operations. Energy sources, such as electricity and diesel fuel, are also essential inputs for powering the machinery and supporting the mining activities.

The primary output of the hard coal mining industry is, of course, the coal itself. This coal is then consumed by a variety of other industries, including 351 Electricity, gas, steam and air conditioning supply, 241 Manufacture of basic metals, and 201 Manufacture of chemicals and chemical products, among others. The coal may be further processed or refined before being used as an energy source or raw material for various manufacturing processes.
