Dec 06, 2017 Coal mining. Mining operations can negatively impact water supplies, often with long-lasting effects. The fundamental issue involves contamination of nearby rivers, lakes, and aquifers by what comes out of a coal mine—usually highly acidic water containing heavy metals like arsenic, copper, and lead. The process is known as acid mine drainage.It happens when certain substances (typically
India is world's third largest coal-producing country and to meet the future energy demand it will have to produce coal at a faster rate. The coal by opencast mining has been about 80% of the total production. This paper focuses on some of the key air pollution problems arising from increased use of opencast mining.
