A new methodology for the openpit mine production

Dec 01, 2018 This gives rise to the open pit mine production scheduling problem OPMPSP. Due to the fact that extraction should be carried out with a specific angle, known as wall-slope angles, the block extraction process must follow a sequence in which all corresponding blocks located above each block have been removed.
OpenPit Mine Production Planning and Scheduling A

Abstract. Mining is a complex, expensive, yet lucrative business. Todays open-pit mines are huge projects in Australia. To keep the projects profitable, planners and schedulers are under constant pressure to make mine plans that are as accurate as possible and optimize production at
Applications of MILP longterm open pit production

production scheduling of open pit mines. One of the main obstacles in using MILP formulations for open pit production scheduling is the size of the problem. The number of integer and continuous decision variables, as well as the number of constraints required to formulate a real-size mine will set up a computationally intractable problem.
Production scheduling optimization in open pit mines

May 30, 2007 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 ...
Production Scheduling for Strategic Open Pit Mine Planning

Production scheduling is a large-scale optimization problem that must be solved on a yearly basis by every open pit mining project throughout the world. Surprisingly, however, this problem has only...

Production Scheduling of Open Pit Mines Using Particle

Determining an optimum long term production schedule is an important part of the planning process of any open pit mine however, the associated optimization problem is demanding and hard to deal with, as it involves large datasets and multiple hard and soft constraints which makes it a large combinatorial optimization problem. In this paper a procedure has been proposed to apply a relatively ...
