COAL MINING AND THE ENVIRONMENT

Abstract The environmental impacts of coal mining in South Africa are reviewed. The primary impacts arise from mining, particularly underground mining, largely because South African coal mines are relatively shallow. Coal washing gives rises to large waste dumps, which may ignite spontaneously and cause air pollution.
