Carbon dioxide, another greenhouse gas, is released in the combustion (burning) process, when coal is used to fuel electric generators and steam engines. As a result, global warming is probably one of the most significant and widely-felt environmental effects of coal mining. References. Alex Gabbard, "Coal Combustion: Nuclear Resource or Danger".
Until recently, however, the effects of coal on human health have been largely ignored and mining has continued without many appeals for improvement. In both the United States and China, industrial achievements have created a legacy of pollution that is taking a major toll on human health.

mining engineer may also be involved with the closure and reclamation of the mine property,although he or she may share those duties with those in the environmental fields. The fields of processing,refining,and fabricating are assigned to metallurgy,although there is often some overlap in the mineral processing area with mining engineering.
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 workers.
