SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter SRK was contracted by Strata Earth Services to perform a numerical analysis of the McCook Quarry near Chicago, Illinois. The 3DEC analysis was performed to evaluate a series of 3DEC models previously constructed and compare numerical...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter A systematic approach to review and audit Ground Control Management Plans (GCMP) for both open pit and underground operations adds value and provides a clear priority list for continued improvement. The process should be based on...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The Fruta del Norte project is an undeveloped, underground high-grade gold epithermal deposit in the southeast of Ecuador. The deposit will be accessed via twin declines, and ore will be recovered using a combination of transverse...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter SRK Chile’s Rock Mechanics team completed a study of the slope design at Cuajone pit. The Cuajone porphyry copper deposit is located on the western slopes of Cordillera Occidental, in the southern Andes of Peru. The...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter Since 2012, SRK has been working with a major North American producer of agricultural nutrients that owns and operates production facilities in Canada and the United States. SRK has been helping the company’s Mine Engineering department...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter SRK conducted a numerical stress analysis to evaluate sill pillar stability for Tahoe Resources’ Escobal Mine located in southeast Guatemala. The Escobal mine uses LHOS methods to extract 4,500 tpd of high-grade silver ore. The mineralisation...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The Cerro Lindo Mine is the largest underground mine in Peru, currently mining more than 20,000 tonnes/ day. The sublevel stoping method was used with paste backfill, which had been experiencing overexcavation issues at the hangingwall...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The Collahuasi Mine is the world’s third largest copper mine with one of the largest deposits of copper mineral resources. It is located in Chile’s Tarapaca region, 4,400 metres above sea level. Since 2013, SRK has...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter All mining excavations should have an appropriate geotechnical design that takes into account the rock mass structure. The level of geotechnical investigation and design required will be governed by the geological and geotechnical complexity of the...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter Modern photogrammetry surveys can produce highly detailed 3D models of a rock slope. Using a high end DSLR camera with a long focal length telephoto lens, we can construct a model of an open pit slope...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The SRK Vancouver Rock Mechanics team has been working at Cameco’s underground Cigar Lake Uranium Mine providing advanced multidisciplinary geotechnical modelling since the summer of 2015. SRK conducted geotechnical and structural geology reviews, which led to...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The Hollinger Open Pit, one of Goldcorp’s Porcupine Gold Mines, is situated in the gold-mining City of Timmins, in northern Ontario, Canada. The Porcupine Camp, located above a sequence of Archean basaltic volcanic rocks, led to...

SRK News | Issue 54 : Rock Engineering and Slope Stability A4 | Letter The requirement to optimise excavation design and minimise waste stripping is becoming more critical in pit engineering as pits deepen and economics become tighter. Representative structural data is critical when optimising pit slope angles and in...
