Hard coal

cpc code 11010 refers to the industry of hard coal, a vital energy source that plays a crucial role in the global economy. Hard coal, also known as bituminous coal, is a type of fossil fuel that is extracted from the earth's crust and used primarily for electricity generation and industrial processes. As a major contributor to the energy mix, the hard coal industry is essential for powering economies and supporting industrial development worldwide.

The production of hard coal involves a series of complex processes. The first step is the extraction of the coal from underground mines or surface mines, using specialized machinery and techniques. Once extracted, the coal is then processed to remove impurities and prepare it for transportation and use. This may involve crushing, screening, and washing the coal to improve its quality and consistency.

The hard coal industry requires several key inputs for its operations. These include the raw material itself, which is the coal deposits found in the earth's crust. Additionally, the industry relies on mining equipment, such as excavators, conveyor belts, and transportation vehicles, as well as energy sources to power the extraction and processing activities. Labor, in the form of skilled miners and technicians, is another essential input for the industry.

The primary output of the hard coal industry is the coal itself, which is then consumed by various sectors, including 11020 Lignite power plants, 23100 Coke ovens, and 24100 Iron and steel. The coal can be further processed and refined into different grades and types, each with its own specific applications and end-users. The hard coal industry also generates byproducts, such as coal ash and slag, which can be used in other industries or for construction purposes.
