The goal of mass haul planning is to determine these amounts and the goal of mass haul optimization is to minimize either or both. [ 2 ] Now they can be performed with a computer and specialized software, including optimisation on haul cost and not haul distance (as haul cost is not proportional to haul distance).

The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
In geology, a nappe or thrust sheet is a large sheetlike body of rock that has been moved more than 2 km (1.2 mi) [1] or 5 km (3.1 mi) [2] [3] above a thrust fault from its original position. Nappes form in compressional tectonic settings like continental collision zones or on the overriding plate in active subduction zones.
