Our rigorous mine planning methodology focuses on pit optimization relative to grade cut-off strategy, economic mining depth, and size and scale of operation. The result is a life …
4. Although the basic concept of an open pit is quite simple, the planning required to develop a large deposit for surface mining is a very complex and costly undertaking. At one mine, it may be desirable to plan for blending variations in the ore so as to maintain, as nearly as possible, a uniform feed to the mill. At another operation it may …

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 …
1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations, …
With K-MINE, you can automatically design open pits, dumps, and other elements of mining operations online. A road ramp is constructed to the entire depth of an open pit. …
The two volumes, however, make up a comprehensive guidebook of all aspects related to mine planning and design and are an excellent reference for aspects such as the …
Existing methods of pushback (phase) design are reviewed in the context of "gap" problems, a term used to describe inconsistent sizes between successive pushbacks. Such gap problems lead to suboptimal open pit mining designs in terms of maximizing net present value. Methods such as the Lerchs-Grossman algorithm, network flow …
It is supplied in the interests of better and SAFER pit design for the mining industry. When we at Deswik run design courses, we are …
The second contribution is a formulation and methodology for the ultimate pit problem with minimum mining width constraints. These operational constraints restrict the shape of …
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used when mineral or ore …

Open-pit mines are surface excavations created to extract valuable material which, in most cases, is located near the surface. Pushbacks are connected regions of a mine with enough working area to support the mining operation over a defined period. Pushbacks designed without taking into consideration haulage ramps are defined here …

JOURNAL OF MINING SCIENCE Vol. 50 No. 3 2014 OPTIMIZED OPEN PIT MINE DESIGN, PUSHBACKS AND THE GAP PROBLEM—A REVIEW 515 While this approach can provide some useful results, it was found [13] in practice that the algorithm was too slow for large mines. Heuristic techniques of combining adjoining blocks and averaging their …
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 …
Mining and milling. Markus H.A. Piro, Ksenia Lipkina, in Advances in Nuclear Fuel Chemistry, 2020 8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground …
