THE HEALTH EFFECTS OF BREATHING THE AIR NEAR COAL MINES Air pollution takes different forms. We can''t see most of the things floating around in the air, but these things, called particulate matter (PM), can damage our health. • PM10 particles measure between and 10 micrometers (from 25 to 100 times thinner than a human hair). These coarse
Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles are one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause an immense amount of pollution.

The Clean Air Act and The Clean Water Act require industries to reduce pollutants released into the air and water. The coal industry has found several ways to reduce sulfur and other impurities from coal. The industry has also found more effective ways of cleaning coal after it is mined, and some coal consumers use low sulfur coal.

By controlling the amount of air and steam, it can be ensured that significant amounts of carbon monoxide (CO) and hydrogen (H2) are formed. Production of CO2, which is a greenhouse gas, can be minimized. Careful systematic studies have been conducted to arrive at the regime of operation, air to coal and steam to coal ratios.

Oct 13, 2010· Most of the ill effects of coal mining today are due to pollutants that are released during the mining process. Most of this pollution is caused by a technique known as mountaintop removal, in which the ''overburden'' above a coal seam is removed into valleys, along with other waste from the mining process. Mountaintop removal exposes toxic contaminants in the ground that are found along with coal.
