Coal mining, especially open-cast mining, is responsible for complete environmental destruction, and has huge impacts to local water resources; groundwater needs to be pumped out of the ground, forests needs to be cut down and fertile top soil are removed in order to access the coal; and in the process destroying valuable underground aquefers, streams and rivers.

4. It may be abundant now, but coal is not replaceable. We cannot replace coal once it has been harvested from its deposit. The process required to form coal involves up to 10 times the amount of plant debris, in volume, to produce coal. That means it is not cost effective or practical to replicate coal production within a laboratory environment.

Coking coal is used in large-scale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more stable product. The steel industry relies on coking coal. Bituminous coal accounts for almost half of all the coal that is used for energy in the United States.

Fossil Fuels and The Environment. Fossil fuels are natural non-renewable resources formed by a natural process of the decomposition of plants and other organisms, buried beneath layers of sediment and rock, and have taken a long time (quantified in terms of millions of years) to become carbon-rich deposits (Nunez, 2019).

The coal industry mainly impacts the environment by reducing the value of the natural environment, accumulation of waste, water pollution, and air pollution. Strip mining, which is the method of choice for coal mining, results in the removal of all existing vegetation, leads to permanent alteration of the land’s topography and destroys the genetic makeup of the soil.

The process is technical, but here’s the gist: essentially, coal is heated to super-high temperatures (more than 1,000 degrees celsius) to make a carbon-dense substance called coke. The coke is combined with iron ore — iron and oxygen — in what’s known as a blast furnace.

Coking Coal for steel production and alternatives. Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals.

This process continues along parallel strips of land so long as the ratio between the overburden and the coal seam, called the stripping ratio, makes it economically feasible to recover coal. Mining may cease in a particular area, for example, where the coal seam becomes thinner or where the seam dips further below the surface.
