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.

The Prince Lyell orebody at Mount Lyell Mine has a rich mining history commencing with the open pit in 1935, which transitioned underground in 1972. 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 …
From the geotechnical point of the view, to the remnants of historical mining operations belong also the anthropogenically formed land structures resulted from the open pit mining (meadow iron ore was subject of scattered extraction in these region), waste dumping, and landfilling.
mass. Geotechnical logging parameters gathered on site are dependent on the classification system to be applied for the geotechnical design requirements. Rock Mass Rating system (RMR), Mining Rock Mass Rating system (MRMR) as well as Geological Strength Index (GSI) are used, however the addition of the In-situ Rock Mass Rating system (IRMR) and
It presents the results from a Pilot Project with a controlled mining operation near caves, in an iron ore open pit mine. This mining complex belongs to Vale SA, a mining company in Carajás, where it was applied a pioneer geotechnical instrumentation monitoring of caves, with remote data transmission.
Key Points • The choice of mining methods and processing parameters for uranium recovery depends on multiple factors that are primarily associated with the geological and geotechnical characteristics of a uranium deposit—its mineralogy and rock type, as well as a range of other factors.
· 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 semi-weathered mafic.

Improving Performance through Benchmarking SRK Russia was engaged by a local client to review several of its iron ore operations, open pit and underground, to determine what increases in capacity could be achieved through removing bottlenecks in its current operations.
We have geotechnical engineers who work closely with both our mining and mine geotechnical groups. This allows us to provide complete coverage of mining infrastructure for our clients. Our Civil Team covers areas such as infrastructure foundations, working areas, mine roads, drainage, creek diversions, water dams and tailings dam investigations.
Marcus Jacobs has over 20 years' experience in operational mines, engineering studies and business consulting roles. He started his career in open cut gold and iron ore mines in Western Australia, and in his career has had exposure to a number of commodities including: gold, iron ore, limestone, copper, lithium and tantalum.
The required input parameters for such numerical simulation are generally obtained from laboratory tests. An iron mine in Yuhezhai, Yunnan, China, and a copper mine in Bahuerachi, Mexico, are going to be constructed, and the plan is to dispose of produced tailings in tailing reservoirs.

because of favourable geotechnical parameters.-Mineable seams have high quality ore, Cr2O3> 46, Cr/Fe > 2.6 but average seam thickness 11cm (unfavourable). Average friability is 30% .Seam dip 27-35 degrees. Continuity around 87 %. - Most mining in the area is underground by incline shafts, winces and adits. Unit cost of mining is high.
