  • Water Active: Borehole Management in Civil Engineering Projects

    Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or any other application , the well performance must be optimized and high levels of operational efficiency and service availability achieved. A ...

  • Engineering exploration

    Resistivity method uses in engineering usually involve mapping void for construction safety purpose. One survey ZZ did was to use crosshole resistivity method to verify the size and location of two karasts. Due to site limitation, only 32 and 20 electrodes were used. The inversion image found two low resistivity areas next to the borehole, which resemble the void. Latter drilling conferred with ...

  • Scanning proposed borehole locations for Utilities case study

    Environmental and engineering firms often are tasked with performing soil borings for monitor well installation as part of a Phase II Environmental Site Assessment. This task becomes more challenging when the borings are to be installed in gasoline stations, right of ways or other areas where there are numerous underground utilities that are either unmarked or not properly located. GeoView can ...

  • Deployment of a Deep Borehole Observatory at the High La ke Project Site, Nunavut, Canada

    Abstract We deployed a deep permafrost observatory in a borehole at the High Lake Project Site (67°22'N, 1I0°50>W), Nunavut, Canada with the aims of (1) investigating the physical and chemical limitations on microbial life within such environments, (2) developing life-detecting technologies for the exploration of life on Mars and (3) constraining the hydrological and thermal ...

  • Channel Tunnel rail link - groundwater model of the basal sands and chalk

    ESI used a groundwater model of the basal Sands and Chalk underlying central London to assess the dewatering impacts of tunnelling as part of the construction of the Channel Tunnel Rail Link (CTRL). A number of boreholes were to be installed for dewatering purposes whilst the tunnel was being driven.  Due to access constraints, the selection of borehole locations was difficult.  The ...

    FlashRES resistivity system is very flexible in terms of application, it can perform: Surface surveys Surface borehole surveys Crosshole and multiple-holes surveys Surface-points surveys High efficient Mise a la Masse surveys 3D survey Time lapse surveys These survey times can be applied to engineering, mining, arachaeology and ...

  • A folded wedge model for determination of true stratigraphic thickness in directional wells

    For exploration and development the geologists and engineers try to know the true stratigraphic thickness (t). The monoclinal and folded bed models are published methods for t calculation. Both models assume parallel beds which can lead to significant deviations. In order to calculate the values of t considering the effects of both folding and stratigraphic variation we propose the 'folded wedge ...

  • Railroad survey application

    Introduction The GPR technology has been introduced to the railroad engineers as one of the easy tools for quick and non-invasive railroad inspection. Since these surveys tend to stretch for a number of kilometers the amount of data can be overwhelming. However, with some clever preparations and proper tools for post processing the data one can create swift and easy to understand ...

  • Reaching underground resources

    Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

  • A comparison of trenchless pipe bursting vs. conventional open cut methods for water and wastewater transmission mains

    ABSTRACT Over the last 15 years, new advances in trenchless technologies have emerged across Europe and are finding their way into the United States. One of the fastest growing methods involves pipe bursting of existing pipe and replacement with new larger diameter pipe. The existing pipe is shattered into small pieces and pushed into the surrounding soil. A new pipe of like or larger size is ...

  • CFD modelling of nitrogen injection in a longwall gob area

    This paper describes computational fluid dynamics (CFD) simulations conducted to investigate the effectiveness of N2 injection in an active panel and a sealed longwall gob area to prevent and suppress spontaneous heating of coal using various injection locations and flow rates. In the active panel simulations, a single longwall panel with a bleederless ventilation system was ...
