Coal is a fossil fuel, like oil and natural gas, formed from plant remains from millions of years ago. As plants died layers of sand and mud covered their remains, forming a soggy, sponge-like material called peat. Over several thousand years, the sand and mud compact the peat beneath the earth's surface where increased pressure, heat and chemical alteration turned the peat into coal.
Coal deposits can be traced to different time periods, but most deposits are from more than 300 million years ago.
Coal is used in the steel industry as well as for the generation of electricity.Coal is a cost-effective and abundant energy source.
Coal is mined either in open pit mines (on the surface of the earth) or in underground mines.
Once coal seams are found, mining teams work to estimate the quantity, quality and depth of coal in the area. In open pit mines, the topsoil is first carefully removed and stored where it can be used to restore previously mined areas into thriving ecosystems.
Blasting is then used to break through rocks and other overburden. The rubble and overburden is removed from the mine by large machines called draglines or shovels. Additional blasting is used to free the coal, which is then loaded onto haul trucks and transported to coal handling facilities where it is sized, blended and loaded into trains according to customer specifications. Finally, the coal is taken to power plants, mills or sold in international trade.
Once an area has been mined, the land is reclaimed and restored using topsoil taken from the original site, or from a nearby mine, in keeping with Viewlance Inc's commitment to sustainable development.
Metallurgical coal is used in steel production and it is focus of our projects.
Thermal coal is used to generate heat and power in thermal power plants.
