In heaps in the open air. It is a black shiny carboniferous rock.
It is mined either underground in coal mines, or on the surface in quarries.
Geologically, it is a strata of rock.
It formed in the Carboniferous Geological period from dead/rotting animal and plant life.
From this rotted material , it can be combusted to release heat for energy. Also it can release carbon dioxide, sulphur dioxide, ammonia, methane. In the modern world these gases can be put to industrial use.
The usual place to find coal in heaps is at the steel works, and power station.
At a steel works, coal is naked in coke ovens to make coke, impure carbon , used for iron ore reduction to iron.
At a power station it is combusted to release heat for steam production in order to turn turbines and make electricity.
the coal is designed to absorb heat at when heat hits it it stores that heat ++++ No. The energy is stored by coal simply being a combustible material, so it contains potential chemical energy.
In a coal mine coal dust , mixed with oxygen and methane is known as 'fire damp'. Any flame or electric arc will ignite a flash explosion. Miners often breed canaries (finch type birds), and occasionally take then down the mine. This is because the bird is very susceptible to poisonous gases and fire damp. It is likely to fall off its perch if poisonous gases are present, whereupon the bird is quickly removed to cleaner air , where it recovers. Coal dust , coal particles are best kept under control by the use of a fine spray / mist. of water.
Coal is sprayed with water to suppress dust and reduce the risk of fires or explosions. Coal dust can be highly flammable and can ignite easily, posing a safety hazard in coal mines, power plants, and transportation. By spraying water on coal, the dust particles are weighed down and kept moist, minimizing the risk of combustion.
Coal Bunker, Coal scuttle, Coal hod
Bituminous coal, or soft coal
Poland is the leading producer and keeper of coal!
Scrooge kept a small fire that he could warm his chilled feet by as well as a small coal scuttle that contained coal and a few scanty ashes in his coal box.
Railroads was the main reason why the coal industry kept in business, it depended largely in the railroads

The coal filters the water so the plants don't get infected from water that is not changed a lot. Some people believe it benefits the plants too but I am not one of those people.
Producers also have kept a close eye on China, which produced 1.2 billion tons in 1998--and which boasts massive coal reserves in excess of 800 billion tons.
It typically refers to the fuel storage. Coal bunkers or fuel oil bunkers are where the fuel is kept.
There are many reasons coal is important to life on earth, a main one is power. The world runs on electricity now, and coal is a main source of power. also fires, coal has always been important in fires.
Coal is kept underground in mines. When it is needed, it is dug up and shipped to power stations where it is burnt to produce electricity.Oil is similarly kept underground. After it has been pumped to the surface it is stored in tanks, tankers and pipelines for transportation to where it is needed.Natural gas is kept the same way as oil, in tanks, tankers and pipelines.
Lignite is a soft coal, essentially. An example sentence would be: He was trying to find crystals, but he kept finding more lignite.

Coal is typically stored in several locations, including coal mines, coal preparation plants, and stockpiles at power plants or industrial facilities. It can be kept in large piles or silos to prevent moisture exposure and spontaneous combustion. Additionally, coal may be stored in transportation facilities like rail yards or ports before being shipped to end-users. Proper storage is essential to maintain quality and manage supply.
