Mining of lignite
NACE v2.1 Code: B05.2
About mining of lignite
NACE code 05.2 covers the mining of lignite, a type of coal that is less dense and has a lower energy content compared to other coal varieties. Lignite mining is an important economic activity, particularly in regions where this natural resource is abundant. As a fossil fuel, lignite plays a significant role in the global energy mix, contributing to electricity generation and industrial processes.
Production process
Lignite mining typically involves the extraction of the mineral from surface or underground deposits. Surface mining, also known as open-pit mining, is the most common method, where heavy machinery is used to remove the overburden (soil and rock) to access the lignite seams. Underground mining techniques may also be employed in certain geological formations. The extracted lignite is then processed, which may include crushing, screening, and washing to prepare it for further utilization.
Production inputs
The primary input for the lignite mining industry is the natural resource itself - the lignite deposits. Additionally, the industry requires specialized mining equipment, such as excavators, haul trucks, and conveyor systems, as well as fuel, electricity, and a skilled workforce to operate the machinery and manage the mining operations. Water may also be required for various processing and washing activities.
Production outputs
The primary output of the lignite mining industry is the lignite coal itself, which is then used as a fuel source for electricity generation and various industrial processes. Lignite is often consumed by 35.1 Electric power generation, transmission and distribution and 23.1 Manufacture of glass and glass products industries, among others. In some cases, the mining process may also yield other by-products, such as aggregates or minerals, which can be utilized in the construction or other industries.
