sophistication of pit design, brought about largely by the use of computers, the demand for more precise slope information has become greater. However, the complexity of the rock mass associated with a typical open-pit ore body precludes an easily obtained slope design. Further more, unless specific studies are conducted, the data
Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of
The Pit Design command in Deswik.CAD draws a pit based on existing polylines. It can be used for designing both pits and dumps. In this short video, Deswik Technical Director Wayne Romer shows you how to create and adjust your pit design using expansion layers, bench ramps and switchbacks.
Open Pit Design. The software system contains the tool set that helps to design mine engineering structures, such as pits, dumps, haul roads and railways, in the course of open cut development. Download presentation Book a …
Open Pit Mine Dewatering by V. Straskraba, Senior Mining Hydrogeologist, Dames & Moore, Denver, Colorado, USA In recent years the increase in development of new open pit mines, especially in the Western U.S., is evident. Most of the mining activity is concentrated on open pit mines for coal and uranium.
Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is …

Deswik opens pit design options for miners with SPD module. Posted by Daniel Gleeson on 23rd March 2021. Deswik says it has come up with a way to rapidly create practical pit designs from optimisation outputs as part of miners' strategic planning process with its Strategic Pit Design (Deswik.SPD) module. Developed in direct response to client ...
The 2,129 ha Mareesburg property lies in the southern part of the eastern limb of the BCX. The farm Mareesburg 8JT is located 50 km to the west of the town of Lydenburg in the Lydenburg Magisterial District, Limpopo Province, in the Republic of South Africa. The nearest railhead is situated at the town of Steelpoort, about 35 km to the ...
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, Interactive Wireframe Boolean can be used to boolean the pit DTM against a topographic surface to create a pit shell solid.
planning and design processes employed by surface mining oil sands operations vary in distinct ways from other commodities mined by both hard and soft rock open pit methods. The unique waste handling needs, including tailings disposal, of contemporary oil sands mining requires specific planning considerations.
The design of open pit excavations will endeavour to prevent hazardous and unexpected failures of the rock mass* during the operating life* of the open pit. The importance of a systematic approach to mine planning and design using soundly based geotechnical engineering methods cannot be over-emphasised. Open pit mines can
Open Pit Design in the 90's. This paper describes the latest open pit optimisation techniques,which now go beyond merely finding an optimal outline. The paper starts by briefly reviewing pit design techniques before optimsation. It then goes on to describe the pit optimisation procedure and the extensions to it which allow the automatic ...

The design is controlled by the engineer doing the design. Your company may have a haul road/pit design manual – use it if it exists. For those that do not have a design manual, or only have limited guidelines, then this article may help you in the process of designing your first pit. The end-purpose of your pit design will likely be:
