  2. 11. On the Use of Engineering Geological Information in Rock Grouting Design

    Author : Sara Kvartsberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Observational method; Transmissivity distribution; Grouting; Design class; Geological prognosis; Fractured rock; Hydraulic domain; Tunnels;

    Abstract : Underground rock construction is dependent on appropriate assessments of the geological settings at the project site. Relevant geological information must be collected, interpreted and communicated clearly with the aid of engineering geological prognoses. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underground mining; Sublevel caving; Rock mass quality; Borehole filming; Borehole quality; Borehole stability; Borehole instability; Drill monitoring technique; Measurement While Drilling MWD ; Hydraulic in-the-hole ITH drilling; Drill system behaviour; Principal Component Analysis PCA ; Geo-mechanical model; Chargeability; Fracture zone; Shear zone; Cave-in; Cavity; Rock blasting; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. READ MORE

  5. 13. Analytic Element Models for Groundwater Flow and Linear Elasticity in Fractured Rocks

    Author : Erik Toller; Auli Niemi; Otto Strack; Qinghua Lei; James Craig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytic element method; fractures; tunnels; complex variables; linear elasticity; groundwater; fractured rock; Hydrology; Hydrologi;

    Abstract : There is an increasing demand for using deep underground space at various scales, such as small-scale geothermal wells and large-scale projects like tunnels or nuclear waste disposal. The deep underground space in fractured rock is a heterogeneous and challenging medium. READ MORE

  6. 14. Hydraulic conductivity relations in soil and fractured rock : fluid component and phase interaction effects

    Author : Jerker Jarsjö; KTH; []
    Keywords : ;

    Abstract : The hydraulic conductivity of soil and fractured rockdetermines the rate at which fluids and dissolved chemicals flowthrough the subsurface, for given conditions at the boundary.Hence, the estimation of relevant parameters for quantificationof hydraulic conductivity relations constitutes a critical basisfor accurate model predictions.
