Coal mining generates significant adverse environmental impacts. Historically, coal mining has been a very dangerous activity and the list of historical coal mining disasters is a long one. Underground mining hazards include suffocation, gas poisoning, roof collapse and gas explosions.
But the most immediate harm to the land is the strip mining by which the coal is extracted. Strip mining reduces hills, farms, and forests to bare earth, caked mud, protruding rock, subsiding land, and flowing silt on a geological scale. The mines are not as bad as they once were.
