  1. 1. Novel methods for 3-D semi-automatic mapping of fracture geometry at exposed rock faces

    Författare :Quanhong Feng; KTH; []
    Nyckelord :3-D laser scanner; close-range photogrammetry; engineering geology; fracture geometry; fracture mapping; rock engineering; rock faces; rock mechanics; three-dimension; total station;

    Sammanfattning : To analyse the influence of fractures on hydraulic andmechanical behaviour of fractured rock masses, it is essentialto characterise fracture geometry at exposed rock faces. Thisthesis describes three semi-automatic methods for measuring andquantifying geometrical parameters of fractures, and aims tooffer a novel approach to the traditional mapping methods. LÄS MER

  4. 3. Draw control strategy for sublevel caving mines : A probabilistic approach

    Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Matthias Wimmer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control; sublevel caving; probability models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER
