The Contour or Bench method of surface or strip mining is usually associated with coal, where a seam or multiple seams are lo ed at a certain elevation or elevations through a mountain or hill. Contour mining allows for the extraction of coal from mountainous areas, where it is not feasible to extract the entire seam, using mountain top Contour strip mining coal mining BritannicaOther articles where Contour strip mining is discussed: auger mining: Augering is usually associated with contour strip-mining, recovering coal for a limited depth beyond the point where stripping becomes uneconomical because the seam of coal lies so far beneath the surface.Strip mining BritannicaStrip mining, removal of soil and rock overburden above a layer or seam particularly coal , followed by the removal of the exposed mineral. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type.
