Structurally defined squeezing mechanisms in hard rock mining often result in buckling failures and large deformations. In mining drives, the primary objective is to mitigate and manage, in a cost-effective way, as opposed to arrest the deformation. This paper is a contribution to an improved understanding of the impact of several reinforcement scenarios in structurally controlled deformations in hard rock mines. The influence of reinforcement in the 3D discrete element method is explored, extending previous numerical work that has captured the squeezing buckling mechanism driven by foliation and high stresses in the selected mine site. A comprehensive strategy for explicitly modelling rock reinforcement using the DEM was developed and implemented in a series of 3D numerical models. The models were calibrated based on field testing of reinforcement and observations at the LaRonde Mine. They were used to investigate the influence of different reinforcement strategies at different deformation stages. The numerical results were in agreement with the field observations and demonstrated the practical implications of using yielding reinforcement elements. This was supported by field data where the use of yielding bolts reduced the drift convergence and rehabilitation. The methodology is applicable to other mine sites facing structurally controlled large deformations. © 2016 Springer-Verlag Wien

The Archean Bousquet 2-Dumagami deposit is an Au-rich volcanogenic massive sulfide deposit (VMS) with a total production of 3.87 Moz Au, 2.77 Moz Ag, 80,000 metric tons (t) Cu, and 5,000 t Zn. The deposit is located within the Doyon-Bousquet-LaRonde mining camp in northwestern Quebec and hosted by the 2704 to 2695 Ma Blake River Group, the world's most productive volcanic assemblage for Au-rich VMS deposits. The Bousquet 2-Dumagami deposit consists of stacked, deformed, and transposed semimassive to massive pyrite-rich lenses, breccia zones, and associated sulfide veins and stringer zones hosted by the upper member of the Bousquet Formation, ~50 to 100 m stratigraphically below the <2687 Ma Cadillac Group sedimentary rocks. The main ore zone is known as the Massive Hangingwall zone at the Bousquet 2 mine and Zone 5 at the Dumagami mine. Another semimassive to disseminated pyrite-rich auriferous zone with coarsely recrystallized massive pyrite is present in the footwall (Massive Footwall zone). The Massive Hangingwall zone is an Au-Ag- Cu-Zn sheet-like, semimassive to massive, pyrite-rich sulfide lens intermixed with vein and breccia zones. The dominant ore type consists of Au-Cu mineralization, but its upper and eastern parts are enriched in Zn. The ore consists of a complex assemblage of sulfides, sulfosalts, and native gold, including abundant pyrite, sphalerite, a few percent of chalcopyrite, bornite, and galena, with some visible gold. The Massive Hangingwall zone was formed by subsea-floor replacement of footwall calc-alkaline dacitic volcaniclastic rocks and hanging-wall blue quartz-phyric rhyolite. Despite significant north-south shortening and metamorphism, which was responsible for transposition, flattening, folding, and recrystallization, mineralogical gradients related to alteration-induced compositional variations can still be identified. A number of different metamorphic mineral assemblages can be mapped over several tens of meters from distal to proximal to the ore: (1) quartz-muscovite ± Mn-garnet ± biotite ± chlorite; (2) quartz-muscovite ± pyrite; (3) quartz-muscovite-andalusite-pyrophyllite- pyrite with topaz and diaspore; and (4) massive quartz-pyrite. A quartz-carbonate-biotite assemblage occurs in the hanging wall of the Zn-rich Massive Hangingwall zone and is hosted by andesitic sills. The thickness of each of these assemblages varies from a few meters to tens of meters. All metamorphosed alteration assemblages are characterized by strong progressive Na2O depletion. Gains in MnO, Fe2O3(total), MgO, and CaO are recorded in the quartz-muscovite ± Mngarnet ± biotite ± chlorite assemblage, whereas gains in K2O and losses in CaO occur in the quartz muscovite ± pyrite assemblage. In the quartz-muscovite-andalusite-pyrophyllite-pyrite and the proximal massive quartzpyrite assemblages all oxides, except SiO2, Fe 2O3(total), and TiO2, were strongly to almost entirely leached. The andalusite-kyanite-pyrophyllite-bearing aluminous assemblages are interpreted to represent metamorphosed equivalents of synvolcanic alteration produced by acidic and oxidizing hydrothermal fluids (i.e., metamorphosed advanced argillic-style alteration), whereas the massive quartz-pyrite assemblage is similar to the massive silicic alteration commonly associated with advanced argillic alteration. The timing of Au mineralization is considered to be close to the age of the host rhyolite (2697.8 ± 1 Ma) and the age of the overlying felsic volcanic rocks (2697.5 ± 1.1 Ma). The major Au endowment of the Doyon-Bousquet-LaRonde mining camp may be related to favorable source rock or Au reservoirs specific to the lower crust or upper mantle beneath the eastern Archean Blake River Group. Exploration for additional Au-rich VMS in this environment should focus on distal quartz- and Mn-rich garnet-biotite and proximal aluminous assemblages with anomalously high Au and/or Cu and Zn in intermediate to felsic transitional to calc-alkaline volcanic or volcaniclastic rocks located underneath a younger sedimentary cover. © 2014 Society of Economic Geologists, Inc.

Surface paste disposal (SPD) is a new alternative employed by the mining industry for storage of mine tailings at the surface. In comparison with the conventional slurry tailings disposal, SPD could offer operational and environmental advantages, such as a better water management, no need for complex retaining dams, a reduced footprint of the tailings disposal area, and the possibility to use progressive reclamation. This paper describes a field investigation through a large-scale experimental cell to assess an SPD application for sulphidic mine tailings. The work addresses the effect of two disposal configurations (i.e., partially cemented and un-cemented) on their hydrogeological behaviour when submitted to actual climatic conditions, focusing mainly on the implementation challenges as well as on the first results obtained. Tailings were deposited in thin layers (10 layers of 10 cm each one) into two experimental cells (D × L × H = 8 m × 15 m × 2 m). Cement was added locally (2 wt.% of Portland cement) in the first layer of the cell (CC) to study its effect; the second cell (UC) is cement free. The evolution of volumetric water content θ, suction ψ, oxygen consumption and cracks for each cell was monitored during and after deposition. Results show that the CC provides slightly higher θ and smaller ψ values than the UC, most likely due to its geological properties dictated by the bottom cemented layer. © 2014 Elsevier B.V.

Managing the mine-to-market process is a complex challenge for any company. Manual methods and point software solutions cannot start to address the intricacies and the need for real-time visibility that characterize today's closely interrelated commercial and outbound logistics processes. The Agnico Eagle company experienced this firsthand as it grew from a single operation to seven operations spanning three countries and from providing a handful of products to more than 20 different products - all in the course of a few years. A unified platform approach to automation has helped Agnico Eagle overcome the complexities of today's market business processes and has empowered the company to reduce costs and improve commercial outcomes.

Agnico-Eagle's flagship LaRonde Mine is exploiting a world-class Au-Ag-Cu-Zn-Pb massive sulphide lenses complex. It is located in the Abitibi Region of north-western Quebec, approximately 650 km northwest of Montreal. With 5 million ounces of gold in proven and probable reserves, LaRonde has one of the largest gold reserves of any mine operating in Canada. These reserves extend from surface down to 3110 m and remain open at depth. The 2250 m Penna shaft, which is believed to be the deepest single-lift shaft in the Western Hemisphere, is used to hoist LaRonde's ore production of y7200 tonnes per day. Current mining operations are taking place at over 2400 m below surface. In 2006, the decision was taken to sink a winze in order to access the ore below 2450 m. The new no. 4 shaft extends to a depth of y2840 m below surface. With the use of ramps the mine will access reserves as deep as 3110 m. Production from shaft no. 4 is scheduled to begin late in 2011, with the full production rate reached in 2013. It is expected that the LaRonde Extension will extend the mine life well beyond 2020. Sinking a winze shaft and building all the necessary infrastructure of a mine at a depth of over 2-8 km poses unique challenges, some of which are discussed. © 2011 Institute of Materials, Minerals and Mining and The AusIMM.

The Kittila underground mine is extracting one of the largest known gold deposits in Europe and has an estimated mine life through 2034. The Kittila mine is located in the Lapland region of northern Finland, approximately 900 kilometres north of Helsinki and 150 kilometres north of the Arctic Circle. The ore at the Kittila mine is refractory, making gold extraction relatively difficult because the gold is generally locked inside the two main sulphide minerals - arsenopyrite and arsenic-rich pyrite. The orebody consists of a complex pinch-and-swell structure including up to 100 different gold mineralization lenses. Fluctuating gold prices and other economic considerations increase the need to maintain and update the mining plans more frequently. Over 3,000 stopes need to be designed and optimized once a year for the LOM-plan and more frequent updates are needed for mid- and short term plans as well as production studies. As a large part of ore body is very sensitive to cost and gold price changes, stope optimization is crucial to find the best possible production scenario for every moment. Kittilä has gone through several methods for stope design and optimization. Most recently the Deswik Stope Optimizer (Deswik. SO) has been successfully used. Dewsik. SO has helped Kittilä to design and optimize stopes in a timely and cost efficient manner. Together with the Deswik suite of planning tools, reliable and auditable plans are created. This paper describes the methods used for stope design and optimization at Kittilä. Copyright © 2015 by SME.
