The impact of acid mine drainage in South Africa
The impact of acid mine drainage in South Africa

The water is acidic as a result of its reaction with pyrite in unmined coal and in the host rocks. Opencast mining involves blasting and removal of the rocks overlying the coal layer, which is removed completely.
