Productivity is often ill-defined as more output for fixed input or the same output for less input. In our opinion productivity gain should be measured as a form of optimization i.e. the highest ratio of output to input which could in fact mean achieving higher productivity with lower input.

Surface Coal Mining and Reclamation. Surface coal mining involves disturbing overlying rock layers (overburden) to expose and extract coal reserves using the area mining method wherein the overburden above the uppermost coal seam and the innerburden between the lower coal seams are removed in parallel strips (pits) across the coalfield until the area is mined.
