Operations planning and management of a large open pit mine is an enormous and complex task, particularly for mines having long life. The long-term planning of open pit mine is a dynamic process and should be reviewed periodically for enhancing the NPV and life of mine. Pit optimization through soft computing can be gainfully …
The open-pit coal mining has the characteristics of high recovery and high safety factors, open-pit coal mining can bring huge economic benefits to the mining area 4 – 7. In the mining design of open pit coal mine, planning reasonable production capacity is an extremely important factor to be decided.
SYNOPSIS Long-term production scheduling is a major step in open pit mine planning and design. It aims to maximize the net present value (NPV) of the cash flows from a mining project while satisfying all the operational constraints, such as grade blending, ore production, mining capacity, and pit slope during each scheduling period.
We consider both direct block scheduling and bench-phase scheduling problems, with capacity, blending, and minimum production constraints. Using new …
This paper presents a two-stage clustering-MILP algorithm for long-term production planning in open-pit mines. The research integrates multi-range stockpiles in the decision-making process that leads to determining the optimum number of stockpiles required to maximize the discounted value of the mine, as well as balancing the quality …
In seeking to maximise NPV (Net Present Value), open pit mining schedules depend on optimal sequencing of pit progress along with ore-waste segregation.

A new method based on block clustering was proposed to reduce the model size and led to a significant reduction in solution time from 372 hours to 23.4 seconds compared to the original block model. Production planning of an open pit mine is defined as determining the extraction sequence of blocks in the final pit limit with the goal of …
The long-term open pit mine production planning is a large combinatorial optimization problem that involves specifying the blocks extraction sequence and their destination during mine life.

The open-pit mine production scheduling problem (OPMPSP) in the traditional T&S system consists of scheduling the extraction of a mineral deposit that is broken into a number of smaller segments, or blocks, across a horizon of several periods in order to maximize the total discounted profit known as net present value (NPV) from the …
A strip is defined as available for storage (z k, p = 1) only if it is located between the top and bottom one.The set {k ∈ K z k, p = 1} defines the in-pit zone reserved for storage. Fig. 3 gives explanations about these constraints. The axis corresponds to the strips, from South to North, the blue strips are the top and bottom ones and the red strip …

The open pit mine optimization problem is con-cerned with the scheduling of mining activities over the life of an open pit mining project. Two variants of the problem commonly solved are (i) the ultimate pit limit problem and (ii) the open pit phase design problem. A closely related problem is the open pit production scheduling problem.
