  • What is the purpose of soil boring and borehole logging?

    What is the purpose of soil boring? Soil boring is a practice of geotechnical investigations whose purpose is to determine the soils load-bearing capabilities, water table and chemical contamination.  Boring is important because (1) it helps to determine the capacity of the soil to provide support to the structures on the surface, (2) it reveals the permeability of the soil ...

  • New USP Guidance on Heat Sanitization: Keep Temperatures Below 80°C

    USP concurs: SnowPure’s experience says that heat sanitization should be between 72-80°C: Bacteria are killed at temperatures above 65°C. Most bacteria are killed at 60°C, and essentially all bacterial are killed above 65°C. Two common protocols have emerged for sanitizing validated high purity water systems:72°C for 30-60 minutes (bacteria killed in ...

  • Parking Ramp over Light Rail Station - Case Study

    Project Description The Minneapolis-St. Paul International Airport (MSP) serves about 36 million passengers annually, via about 405,000 flights. On-airport parking provides about 22,900 parking spaces and is frequently at or near capacity. A parking ramp expansion has been proposed at Terminal 1-Lindbergh. It will be constructed over the north end of the Metro Transit Light Rail (LRT) ...

  • Rock Mechanics Pre-Feasibility Studies

    Project Description When starting a new mine, whether it's a open pit or an underground mine, the designer faces many challenges! One of these is the understanding of rock mass conditions and how this affects the choice of mining methods and the mine design at an early stage. OFFICE Sweden Itasca Consultants AB ...

  • Evaluating Multiple Mechanisms & Structural Forces in Slope Stabilization - Case Study

    Project Description Unlike slope stability analysis software based on the limit equilibrium method, Itasca’s numerical modeling software (FLAC, FLAC3D) is capable of predicting multiple interacting failure mechanisms and produces the structural forces in the stabilization features. These capabilities are critical to developing engineering judgment and in designing remedial ...

  • Laver Rock Mechanics Pre-Feasibility Study - Case Study

    Project Description Boliden is investigating the Laver low-grade copper deposit for potential future mining. The old Laver deposit was discovered in the 1930s, and was operated between 1938 and 1946. Mining was primarily conducted as small-scale underground mining, but a small open pit was also in operation at that time. The currently investigated deposit is of larger scale and with lower ...

  • Crookston Crookston Landslide Stabilization - Case Study

    Project Description In 2003, a landslide developed along the Red Lake river bank inside the city of Crookston, Minnesota. Although several attempts were made to solve the problem, in 2008, a second event occurred, and extensive instrumentation was then put in place to monitor the slope and gain a better understanding of the situation. In 2013, the Minnesota Department of Transportation ...

  • Rock Mechanics Study for the Kevitsa Strategy Project - Case Study

    Project Description The Kevitsa open pit mine has been in operation since 2012 and was acquired by Boliden in 2016. A new strategic plan is currently being developed to investigate an increase in production. In conjunction with this, the geotechnical slope design parameters for the final pit depth, including a possibly deeper pit, need to be analyzed. OFFICE ...

  • Numerical modeling of dredged sand filled geotextile tubes behavior under seismic loading - Case Study

    Project Description A nearshore 120m long causeway is planned for the Mozambique LNG TMOF Project. Geosintex S.R.L. proposes a structure composed by synthetic geotubes (see Figure) for protecting the road against erosion. The mechanical behavior of this structure must be understood better. The evaluation of the potential for liquefaction of the road sandy basement and the geotubes ...

  • Use of a Finite Element Code to Model Complex Mine Water Problems

    Abstract: Numerical models are now used routinely to predict ground-water inflows to both surface and underground mines and to help design dewatering systems. Two of the more complex problems encountered in mine dewatering are 1) predicting the configuration of the phreatic surface and height of the seepage face in pit highwalls for slope stability analysis and 2) predicting inflow to ...

  • Simulation of Three-Dimensional Pore-Pressure Distribution for Slope-Stability Analysis

    Abstract: A 3D groundwater flow model was constructed using MINEDW [1] to simulate pore pressure at the Chuquicamata open pit mine slope in Chile. Three main factors required the implementation of a 3D model for the prediction of pore pressures: (1) discrete zones of recharge in the gravel zone lead to the non-uniform flow field; (2) the low-permeability west fault and shear zones maintain ...

  • Quantifying the Effect of Localized Depressurization on a Deep Underground Ore Body at the Mcarthur River Mine through Cross Hole Hydraulic Testing and Groundwater Modeling

    Abstract: The McArthur River mine in northern Saskatchewan is the largest single producer of uranium in the world. Most of the ore is extracted by raisebore mining methods at depths of 530 to 600 m below ground surface where pore pressures in the fractured host sandstone and gneiss are on the order of 5 MPa. Currently, ground freezing is used to isolate the ore from ground-water sources. ...

  • Practical Open Pit Rock Mechanics - Case Study

    Project Description Open pit mining often result in high rock slopes, sometimes combined with difficult rock conditions. This is further augmented by large blasting rounds resulting in high vibrations. Reinforcement of pit slope walls is also difficult and many times associated with high costs and loss of production. Bench slope stability is vital for a safe working place for all personnel ...
