A New Algorithm for the Open-Pit Mine Production

Open-pit mining consists of extracting commercially valu-able ore from a mineral deposit by digging from the sur-face as opposed to tunneling underground. Hustrulid and Kuchta (2006) describe the open-pit mineral supply process in terms of three important phases planning, implemen-tation, and production. During the planning phase, mining

OPTIMUM OPEN PIT MINE PRODUCTION SCHEDULING

The multi-period open pit mine production scheduling problem is formulated as a large scale linear programming problem using the block concept. A solution procedure is developed through decomposition and partitioning of the subproblem into elementary profit routing problems for which an algorithm is presented. Many of the traditional mine planning concepts are discussed and suggestions for

A Push-Back Sequencing Model for Production Planning

A dynamic sequencing method has been developed to simultaneously optimize the coal production rate, waste stripping rate, mining sequence, and mine life of an open-pit coal mine. The method first establishes a geological seam model of a bedded coal deposit which estimates the relevant attributes of coal seams at the center of each block on the X-Y plane.

Production scheduling optimization in open pit mines

ABSTRACT This paper addresses the problems associated with production scheduling in open pit mines once the ultimate pit limits have been defined. A computer package is presented, capable of evaluating alternative short and long range production schedules. Simulation is employed for long range, and linear programming for short range production scheduling, the objective being to maximize cash
