  2. 1. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique

    Author : Rajib Ghosh; Håkan Schunnesson; Nuray Demirel; Luleå tekniska universitet; []
    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

  4. 2. Analysis of Excavation Damage, Rock Mass Characterisation and Rock Support Design using Drilling Monitoring

    Author : Jeroen van Eldert; Håkan Schunnesson; Daniel Johansson; David Saiang; Thomas Dalmalm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast damage; Excavation Damage Zone; EDZ; Measurement While Drilling; MWD; Rock support; Rock mass characterisation; Tunnelling; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Prior to an underground excavation a site investigation is carried out. This includes reviewing and analysing existing data, field data collected through outcrop mapping, drill core logging and geophysical investigations. READ MORE

  5. 3. Load-Haul-Dump operations in underground mines

    Author : Bartlomiej Skawina; Jenny Greberg; Abubkary Salama; Oliver Langefeld; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LHD; DES; simulation; underground mine; energy consumption; ventilation requirements; orepass loss; production scheduling; process control; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The research presented in this thesis addresses several aspects of loading operations inunderground mines, in particular tools and equipment selection. It also addresses the flexibilityof the fleet when subject to substantial disturbances, such as ore pass loss, and proposes integration of the scheduling system with discrete event simulation.

  6. 4. Draw control strategy for sublevel caving mines : A holistic approach

    Author : Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Laeeque Daneshmend; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control strategy; sublevel caving SLC ; loading process; draw point; caving operation; Bayesian statistics; probability models; economic models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : 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. READ MORE

  7. 5. Inventory of geomechanical phenomena related to train-induced vibrations from tunnels

    Author : Andreas Eitzenberger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Banverket is expecting that the number of railway tunnels in densely populated areas will increase over the next 20 years due to the lack of available space on the ground surface, but also since the railway is considered an environmentally friendly solution of transportation for the future. The need for good predictions of vibration and noise levels in dwellings along the planned tunnels is therefore evident. READ MORE
