Open-pit mining - Global Energy Monitor

Open-pit mines are typically enlarged until either the coal is exhausted, or an increasing ratio of overburden makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake.
