Mining of lignite

isic code 0520 covers the mining and extraction of lignite, a type of coal that is softer and has a lower energy content compared to other coal varieties. Lignite is an important fossil fuel resource, primarily used for power generation and heating. The mining of lignite plays a crucial role in meeting the energy demands of many countries, particularly those with significant domestic lignite reserves.

Lignite mining typically involves surface mining techniques, such as open-pit or strip mining. These methods involve the removal of the overburden (soil and rock) to expose the lignite seams, which are then extracted using heavy machinery like excavators and draglines. The extracted lignite is then transported to power plants or other processing facilities for further utilization.

The main inputs required for the mining of lignite include heavy machinery and equipment, such as excavators, bulldozers, and haul trucks. Additionally, the mining process requires significant amounts of energy, primarily in the form of diesel fuel to power the heavy equipment. Other inputs include explosives for blasting operations, as well as water for dust suppression and other mining-related activities.

The primary output of the lignite mining industry is the lignite coal itself, which is then used as a fuel source for power generation and heating. The 3510 Electricity, gas, steam and air conditioning supply industry is a major consumer of lignite, as it is used in thermal power plants to generate electricity. Additionally, the 1920 Manufacture of refined petroleum products industry may utilize lignite as a feedstock for the production of various petroleum products.
