the role of microorganisms in coal mining

Aug 16, 2015· The formation ofacid mine drainage(AMD), a highly acidic and metal-rich solution, is the biggest environmental concern associated withcoaland mineralmining. Once produced, AMD can severely impact the surrounding ecosystem due to its acidity, metal toxicity, sedimentation and other deleterious properties. Hence, implementations of effective post-miningmanagement practices are …
