BlakeCoal is typically mined from underground or surface mines. In underground mining, miners access coal seams by digging tunnels to extract the coal. In surface mining, large machines remove layers of earth to expose coal seams. Once collected, coal is transported for processing, where it is crushed and washed to remove impurities before being used for energy production.

The energy in coal is used to make electricity how is the energy stored in coal?
The energy in coal is stored as potential energy during its formation over millions of years. This potential energy is released as heat when the coal is burned, which is then used to generate electricity through steam turbines.
How is stored chemical energy converted into thermal energy when coal is burned to make steam?
When coal is burned to make steam, the stored chemical energy in the coal is released as heat energy through a combustion reaction. This heat energy is then used to heat water and produce steam, which in turn drives turbines to generate electricity. The thermal energy from burning coal is transformed into mechanical energy and then electrical energy in this process.
What form of energy does coal make?
Energy cannot be 'made' or 'destroyed'. It can simply be transformed to a different type of energy. Coal contains chemical energy, which will for example, be converted to heat energy in say a coal fired industrial boiler.
The energy in coal is used to make electricity. How is the energy stored in coal?
The energy in coal is stored in the form of chemical bonds between carbon and other elements like hydrogen. When coal is burned, these bonds break, releasing the energy in the form of heat that can be used to vaporize water and generate steam to drive turbines that produce electricity.
Uses of coal?
Coal is primarily used for electricity generation, accounting for a significant portion of global energy production. It is also used in industrial processes such as steel production and cement manufacturing. Additionally, coal is used in residential and commercial heating and as a feedstock for certain chemical processes.
