  • The Social and Environmental Consequences of Coal Mining

    Open cast mining removes large volumes of soil and rock overburden to get to the workable coal seams, and destroys regional aquifers. Mining produces large mountains of solid waste. Coal heaps are prone to spontaneous combustion. Leachate from waste heaps are often acidic, adding to the general and large scale acid mine drainage impact and
