Development of Improved Multiseam Contour Haulback Mining.
NTIS: PB/80-149354 :347 pages
This report summarizes a study conducted to develop improved techniques for haulback mining of multiple seam contour surface operations. The methods employed to perform contour haulback mining are discussed as are the implications of regulations requiring back to approximate original contour reclamation. Problems inherent to multiseam contour surface mines are defined and several potential solutions to those problems are introduced.
