  • Reproducibility of Borehole Shear Test Results in Marine Clay

    An investigation was conducted to determine the variability of borehole shear test results obtained in testing soft and medium consistency marine clays. A statistical comparison of the results of stage tests obtained by different operators at two test depths at a research site is made. An additional comparison of the results obtained from stage tests and fresh shearing and a brief discussion of ...

  • Eolane China Fully Introduces DFM, Design for Manufacturing

    DFM comes from the English abbreviation Design for manufacture. As the name implies, DFM fully considers the needs of manufacturing during the development of new products, so that the products have good manufacturability and reach the highest possible yield at the lowest cost in the shortest time.In the traditional serial product development process, the design aspect always emphasizes the design ...

  • Effects of Borehole Fluid on Standard Penetration Test Results

    The standard penetration test (SPT) represents the most widely used in-situ test method for evaluating the liquefaction resistance of saturated soils. Significant progress has been made in recent years in developing correlations between SPT results obtained using different test procedures and equipment in order to develop a higher degree of standardization for SPT testing. One of the heretofore ...

  • Modeling Pinch-Outs and Steep Topography in RockWorks - Case Study

    Summary Areas with complex stratigraphy (i.e. pinch-outs, folding, faults, etc) are not easily modeled in the borehole manager. One will often have to take the grids originally created with the borehole manager and manipulate them in the Utilities or in other programs. There are several tools available is the Utilities for manipulating your grids. Once you have edited your grids, you can ...

  • How to set up a groundwater monitoring test site

    When it comes to groundwater monitoring, testing the water often requires the creation of a borehole at the test site to reach the water below. The process of creating a safe and secure site for everyone involved can sometimes be a lengthy process. The size of the borehole, which drill to use and the response zone are just a few of the considerations that will need to be taken into account during ...

  • Triaxial permeability testing and microstructure study of hard–to–drain coal from Sydney Basin, Australia

    Several mines operating in the Bulli seam of the Sydney Basin, Australia have coal seam zones that are difficult to drain. Metropolitan Colliery being one of such mines, has experienced difficulties in reducing gas content within the available drainage lead time; as the coal seam would not drain even with additional drainage boreholes. A research study using coal permeability testing and ...

  • Karst groundwater: a challenge for new resources

    Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow, large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s. Different conceptual models, known from the literature, attempt to take into account all these particularities. The ...

  • Pollution mapping case study

    This exploration survey used the cross-hole resistivity method to detect if there was industrial waste water leakage from an industrial waste water process pond. Chemical analyses concluded that this specific waste water has a much lower resistivity than normal water. The figure below shows that the area above 45m is a relatively high resistive zone made of limestone. Below this depth is a middle ...

  • Storing Heat Underground

    Underground thermal energy storage (UTES) is a system that uses inter-seasonal heat storage, storing excess heat from the summer for use in winter heating, and the cooling potential from winter for cooling in summer. A cost-effective, low-energy and low-risk proven renewable technology, UTES reduces carbon emissions by up to 60% and is becoming an increasingly popular choice for residential, ...
