Abstract
Case histories were used to document and evaluate deficiencies in underground mine closures that have resulted in postoperation problems such as subsidence shaft failures, acid or toxic water drainage, and others. Three underground mining districts in the United States were investigated: (1) an iron mining district in Michigan, (2) coal mining districts in eastern Ohio and southern Illinois, and (3) three metal mining districts in central Colorado. The studies show that problems from acid water drainage, subsidence, and inadequately protected mine shafts are the most severe and widespread. Mine closure and reclamation should be considered as a part of mining and be incorporated in the mining plan, which would result in reduced environmental impact.
