ABSTRACT:
A method for extracting mineral deposits is provided. First, a predetermined surface is contour mined to expose a portion of a mineral seam and provide an insertion highwall between a pair of endwalls. Successive mining passes are made through the mineral seam to extract the mineral deposits by moving from one endwall to the other endwall. Advancement of the mining operation occurs in a direction substantially perpendicular to the insertion highwall.
