Jul 29, 2022The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a m ore 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.

Destruction and poison linger. Bad mining practices can ignite coal fires, which can burn for decades, release fly ash and smoke laden with greenhouse gasses and toxic chemicals. Furthermore mining releases coal mine methane, a greenhouse gas 20 times more powerful than carbon dioxide.

This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO 2. To a lesser extent, clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases. How do we know what greenhouse gas and temperature levels were in the distant past?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

The mining of coal destroys natural habitats. To remove coal from the ground, various mining processes are used that destroy the natural habitat in that region. Part of that destruction involves the potential pollution of groundwater tables and the removal of trees. There is also the added danger of having a fire begin in a coal mine.

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.

Mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife.

Climate change is coal's most serious, long-term, global impact. Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits.

Sulfur dioxide (SO2): Produced when the sulfur in coal reacts with oxygen, SO 2 combines with other molecules in the atmosphere to form small, acidic particulates that can penetrate human lungs. It's linked with asthma, bronchitis, smog, and acid rain, which damages crops and other ecosystems, and acidifies lakes and streams.

The burning of coal implies the emission of many harmful gases into our atmosphere. However, instead of burning coal, coal can be converted into liquid fuels, which emit lower amounts of harmful gases into the air. Thus, the emission of harmful gases and particles could be lowered to a certain extent by converting coal into liquids.

With respect to carbon emissions, coal mining and the burning of coal account for a greater sum than any other fuel. Coal, unlike gas fuels and oil, does not emit carbons into the air in its natural state. However, during the mining of coal, methane is released into the air. Tremendous amounts of methane (CH 4) are released into the air in fact.
