While underground mining, which allows coal companies to extract deeper deposits of coal, is viewed as less destructive than strip mining, the effects of mining widespread damage to the environment. In room-and-pillar mines, columns of coal are left to support the ground above during the initial mining process, then they are often taken out and ...
Petroleum Coke: Industry and Environmental Issues Congressional Research Service 3 Petcoke Compared to Metallurgical Coke and Coal Petcoke has a significantly high heating value compared to metallurgical coke (metcoke) and bituminous coals (see Table 2). The higher heating value comes at the cost of higher sulfur and nitrogen content, however.
A coal-fired power plant is a prodigious generator of environmental pollution, releasing large quantities of particles as aerosols in the atmosphere. The inhalation of …

Environmental Impacts. Acid mine drainage (AMD) refers to the outflow of acidic water from coal mines or metal mines, often abandoned mines where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite. Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, …
Coal Mining. Health effects from coal mining include: the release of methane (CH 4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO 2 is estimated to contribute 50%).; the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine …
The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between …
Coal composition and health. The composition of coal depends on the characteristics of the natural coal genesis site, which varies significantly over a few kilometers (Pires and Querol, 2004; Silva et al., 2009; Dai et al., 2020a; O'Keefe et al., 2013). China and the United States are the main coal mining regions worldwide.
