Jul 02, 2015· Mafics are country rocks of the iron ore, which are normally covered by lateritic duricrusts. Based on geotechnical parameters, the mining nomenclatures for mafics are: unweathered mafic, weathered mafic with inferior resistance, weathered mafic with medium resistance, weathered mafic with superior resistance and semiweathered mafic.
His areas of expertise include rock slope waste dump engineering, design and implementation of slope monitoring and risk management systems, structural geology modelling, and technical assurance and compliance auditing. Tim has led geotechnical operational and design teams supporting major iron ore and gold mining operations.
This paper presents examples of several scenarios in which pit slope stability assessment may be required at mine closure. These are focused specifically on the longterm stability of the open pit excavations, not the stability of any adjacent structures. The paper does not attempt to propose a set of guidelines but discusses techniques that may be used for assessment under various scenarios.
Multidisciplinary Extensive experience in geology, geomechanics and geotechnical engineering, for: gold, base metals, industrial minerals and iron ore in a wide range of environments and cultures, from the tropical highlands of Papua New Guinea to the Great Sandy Desert of Western Australia.

Between 1972 and 2014 a total of 64 Mt was mined underground as the mine extended from 210 m to 1100 m below surface. As the depth increased, three separate transitions in the mining method occurred to meet the changing geotechnical conditions, ore grade, mining costs and metal prices.
Figure 5 shows a comparison of selected geotechnical parameters from drillholes intercepting a pit wall through a deeply weathered profiles. Using Leapfrog Geo 3D software, Figure 5 shows the variability in the geotechnical parameters as expected for a rock in the very poor to good rock quality RMR range. (Bieniawski, 1989). 5.

David is a mining geotechnical specialist with 28 years of experience in mining and civil geotechnical engineering in Australia and Papua New Guinea, of which 21 years have been in mining. His experience has been gained throughout a wide range of opencut and underground projects, in the prefeasibility, feasibility and operational phases.
This paper presents results of an extensive laboratory program executed to obtain geotechnical parameters of mining and industrial wastes. Different residues from mining and industrial processing of bauxite were studied. The results of geotechnical characterization tests carried out on all materials are presented and compared.
Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.
Geotechnical Considerations for Mining Method Selection of a Potential Underground Iron Ore Mine in Mideastern, Turkey Levend Tutluoglu, Celal Karpuz, Hasan Ozturk, Dogukan Guner, and A. Gunes Yardimci Middle East Technical University, Ankara, Turkey Abstract. Geotechnical analysis plays an important role in determining mining method selection.
Nimba Iron Ore, Guinea and Liberia. May 2014 Dec 2015 Project: Preliminary Mine Haul Road Design and Geotechnical Investigation Sable Mining Africa Ltd. obtained an iron ore mining concession in the Mount Nimba region of the Republic of Guinea, with Phase 1 of the project comprising the extraction of 3Mtpa DSO (Direct Shipping Ore) from the concession area.
The PIOP commenced in May 2003 as a joint venture between Flinders Diamonds Limited (now Flinders Mines Limited) and Prenti Exploration Pty Ltd (Prenti). In March 2005, Flinders and Prenti agreed with Fortescue Metals Group (FMG) to swap commodity rights on some of the PIOP tenements, with FMG taking the iron ore rights.
In addition, she has performed a planning and management role for geotechnical studies and design outcomes for the iron ore operations of a mining major in Western Australia. Diane has also conducted geotechnical soils investigations and site characterisation for civil and mining infrastructure projects.
Bruce has over 25 years of experience specializing in mining rock mechanics; he leads the Vancouver mining geotech group. Bruce has been involved in mining operational rock mechanics since 1989 in both hard rock open pit and underground operations, including gold, copper and iron ore.
This paper presents an evaluation of the geotechnical parameters that are used to characterise the transition zone materials at the study phase and then refined during pit exposure. Geotechnical characterisation and bench slope performance aspects have been detailed using case study examples from operating mines.
