all about coal

What is coal

This is World Coal Association's definition of coal- coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs

Google definition- a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel

Illinois Coal Association- coal is a black or brown rock that can be ignited and burned to produce energy in the form of heat.

coals chemical makeup is a complex mix of elements that include sulfur, carbon, oxygen, hydrogen and nitrogen, as well as small quantities of aluminum, zirconium and many other minerals

Why do we need to use coal

We need coal because it gives us many benefits such as powering our cars, iron and steel, concrete, plant fertilizer, and shampoo

Coal is used for electricity- coal fired powered stations generate 40% of global electricity. heat from burning coal boils water, and steam spins a propeller. a machine turns this into electricity.

Iron and Steel- About 70% of steel is created using coke, a high- carbon fuel made from coal. It is burning to melt and remove impurities from iron or during iron and steel production.

Concrete- Concrete is a building material made with cement. coal is burned to make heat for cement production. Waste ash from coal fired power stations can be replace cement in concrete.

Plant Fertilizer- coal can be turned into ammonia fertilizer by breaking it into carbon monoxide and hydrogen gas. The hydrogen mixes with nitrogen to make ammonia.

Shampoo- the dandruff and head lice- zapping power of some shampoos is thanks to coal tar, a thick dark colored liquid produced when coal is turned into coke or gas fuel.

An outline of the process for extracting coal

In underground mines, shafts and tunnels are dug down to the coal seams, where the coal is dug out and removed in areas called rooms. Pillars , or columns of coal, are left in place to hold up the ceiling of the rooms. T he coal is dug out with machines and then brought to the surface using conveyors.

A description of specific impacts that extracting coal has on people and the environment

Some impacts on our environment are that when we use coal as a fuel (cars) it pollutes our air and environment. Also eventually since coal is a non- renewable resource we will run out of it and then we will put us in a hard situation because we always depend on cars. It can also have an impact on surface and ground water, soils, local land use, native vegetation and wildlife population. Mining can also cause water polution.

A description of what can be done to reduce the severity of the negative 'impacts' given that the 'impacts' of extracting are negative.

Instead of using cars use things that don't use fuel such as bicycles, skateboards, roller skates, etc. You can also walk places instead of using a car. If you have to drive then see if anyone is going to the same location you are( ex. school) and car pool.
