Causes. Mining operations like drilling, blasting, hauling, collection, and transportation are the major sources of emissions and air pollution. Coal left in the ground can catch fire, and mine fires are difficult to control, with some burning for decades or even centuries, creating a major source of air pollution.
An important step in curbing the pollution created by mining and ore processing is to work with mines and governments to improve mining equipment and environmental regulation. Many pollution problems occur due to a lack of set environmental and health standards, or, when laws do exist, weak enforcement and compliance procedures.
