SYNOPSIS. Mathematical programming has been applied to optimizing open pit mine planning problems since the early 1960s. Nonetheless, it still remains challenging to obtain a life-of-mine plan with current computational hardware and software, mostly because of the scale of the input data, which is generally in the form of mining blocks.
Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
Open Pit Mine Production Scheduling A fundamental problem in mine planning is the determination of the production schedules over the life of the mine. The objective is to …
Abstract. Mining is a complex, expensive, yet lucrative business. Today's open-pit mines are huge projects in Australia. To keep the projects …
Throughout their planning the size, shape and depth of the mine are decided upon along with a sufficient blast outline. Step 2. Probe Drilling Special machines are used for this process. These drills are used to create 16-25 meter probe holes into potentially unstable ground. Using this equipment minimizes injury and costs.

Open Pit Mine Planning and Design - University of Pretoria
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this …
Pit optimization is the process of determining the optimal outline or shell to be mined to in order to maximise the profit while satisfying operational requirements. The starting point of the strategic planning process is a resource block model, in which ore and waste material are divided into regular 3D blocks as shown on Figure 1 below.
This paper presents a new metaheuristic approximation approach based on the Ant Colony Optimization (ACO) for the solution of the problem of open-pit mine production …
Open Pit Mine Planning and Design: Step two Produce a solid wireframe of the pit. The pit shell solid represents the shape and volume of material that will be excavated throughout the life of mine. At this stage, …
Projects Through Mine Planning K.Dagdelen Mining Engineering Department, Colorado School of Mines. Golden, Colorado, USA ABSTRACT: The open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 40 years The development of the "know-how" to improve economics of open pit ...

A Strategic Mine Plan is the first stage of mine planning that sets the economic and technical direction for your project. The correct strategy is vital for the economic, social and environmental success of your project. You may be currently operating with a sub-optimal plan, so take this opportunity to create value and optimise your assets by ...
