Scribd is the world's largest social reading and publishing site. Because of the typically weak 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. 1 Planning for total mine life 13. The main topics that will be discussed in this vi GuidelinesforOpen Pit Slope Design 2. While Guidelines for Open Pit Slope Design Series The books in the Guidelines for Open Pit Slope Design Series were created as an outcome of the Large Open Pit Mine Slope Stability Project, an international research and technology transfer project on rock slope stability in open pit mines. Slope design will typically meet a Design Acceptance Criteria (DAC), and the current practice of designing open pit slopes adopts the industry-wide accepted Guidelines of Open Pit Slope Design published in 2009. As such, they can provide a significant challenge for the slope designer. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit In open pit slopes, design parameters such as the bench angle, the bench width, the backfill height and the backfill width (as shown in Fig. com ABSTRACT The management of the slopes in an open pit mine depends, amongst Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. 6 Coreorientation 28 2. The risk of slope failure that occurred on the slopes of the mine affect two factors namely the failure probability (FP), and consequences The depth of open pit mines has greatly risen because of the rise in worldwide demand for minerals and technical advancements.
