Book Synopsis Guidelines for Open Pit Slope Design in Weak Rocks by : Derek Martin
Download or read book Guidelines for Open Pit Slope Design in Weak Rocks written by Derek Martin and published by CSIRO PUBLISHING. This book was released on 2018-01-10 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability. 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 sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves. This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, monitoring, surface water control and closure of weak rock slopes. As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

Book Synopsis Two- and Three-dimensional Slope Stability Analyses of Open Pit Mines Under Geomechanical Uncertainty and Rock Mass Properties Variability by : Christian Obregon Mitma
Download or read book Two- and Three-dimensional Slope Stability Analyses of Open Pit Mines Under Geomechanical Uncertainty and Rock Mass Properties Variability written by Christian Obregon Mitma and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "In open pit mining, a major geotechnical challenge involves the excavation of the steepest possible slope angle to achieve the lowest stripping ratio while ensuring maximum ore recovery. This generally means a good overall profitability since waste rock removal is kept to a minimum. However, steepening pit slopes may induce failures, which may disprove the economic benefits that were initially aimed at and which may also result in loss of life, damage to equipment and environment. As a result, the selection of slope angle is a critical decision that can have far-reaching effects on the economics and operation of the mining project Traditionally, slope stability assessments for pit slopes are carried out by means of a 2D deterministic analysis. However, there are two major drawbacks with this approach. First, a deterministic approach is unable to account for the variability and uncertainty in the rock mass strength properties. Second, a two-dimensional analysis cannot capture the complex open pit geology and varying geometry which is inherently 3D in character.This work deals with the geotechnical slope design of three open pit case studies by means of a probabilistic-based approach in order account for the variability and uncertainty in the properties corresponding to both the intact rock and geological discontinuities. Rock slope stability assessments are carried out at three different scales: bench, inter-ramp and global pit slope by means of analytical and numerical tools. Both kinematic and kinetic analysis for structurally controlled failure mechanisms were carried out at the bench scale by means of classical Limit Equilibrium Analysis (LEA). Also, a novel Discrete Fracture Network (DFN) modelling technique was used for the stochastic representation of discrete rock blocks. Slope stability analysis at the inter-ramp slope was performed through a deterministic approach of major large-scale discontinuities mapped during field geological characterization. The global pit slope stability analysis focused on investigating the uncertainty in intact rock and rock mass Hoek-Brown shear strength envelopes and was conducted using 2D/3D Limit Equilibrium Analysis (LEA) vs Finite Element Analysis (FEA). Finally, deterministic vs probabilistic, LEA vs FEA and 2D vs 3D slope stability analysis tools are compared, and their results are discussed"--

Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Deep open pits are becoming increasingly common in the mining industry and the consideration of the design of slopes in open pit mines is a classical problem for mining engineers. Many of these pits are being developed in parts of the world where deep weathering has taken place, producing deep deposits of residual soils. However, limited research has been conducted in relation to the engineering properties of these materials and the impact on slope stability in open pits. Generally, residual soils behave differently from transported soils. Strain softening, often leading to progressive failure of slopes are two factors that often need consideration when dealing with the evaluation of slope stability in residual soils. In engineering practice, the limit equilibrium method is the most popular approach for estimating slope stability; however, it assumes the material behaves rigidly, with the strength being mobilized at the same time along the entire failure surface. This cannot account for progressive failure. In order to obtain more reliable results, it is therefore important to consider the potential for progressive failure when designing slopes in strain softening materials. The strain softening constitutive model in a finite difference program FLAC was chosen for use in this thesis. The results of a comprehensive numerical study into the failure mechanisms of slopes in residual soils are presented. The limit equilibrium method is also employed for comparison purposes. Comparisons of the factor of safety from each technique provide an opportunity to validate the findings and give a rigorous evaluation of slope stability. It was found that the strain softening model in FLAC is a potentially useful method to capture the failure mechanism of residual soils exhibiting such behaviour. Another key step in applying this constitutive model is the derivation of appropriate parameters describing the mechanical behaviour...
