Faced with tight customer deadlines, MEC Mining recently delivered multiple mine planning and production scenarios for a major underground coal producer. The scope included a “first principles” mine design and bottom-up productivity review for Continuous Miners and Longwall operation. Coal reserving and production scheduling of multiple scenarios were executed with XPAC which delivered the required inputs to financial modelling.

Out of a total of 19 options (14 in seam 1 and 5 in seam 2) the optioneering process selected the preferred alternative which delivered the best business solution.
