Strip mining and subsurface mining Strip mining (or surface mining) is performed when surface soil and rock are stripped off to reach the mineral of concern. When such operations are done, surface water bodies (lakes, streams, etc) gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals to produce sulfuric acid.
