Evaluation of Current Surface Coal Mining Overburden Handling Techniques and Reclamation Practices.

摘要

An evaluation of mining and reclamation practices at 159randomly sampled surface coal mines in the United States was conducted. Operating procedures for dragline stripping of single and multiple seams,surface mining of lignite, multicut and multiseam haulback mining on steep slopes, mountaintop removal,and surface mining in swampy or deeply glaciated areas are discussed. Specific candidate research projects are noted.
