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

   University dissertation from Luleå : Luleå tekniska universitet

   Author : Rajib Ghosh; Håkan Schunnesson; Nuray Demirel; [2017]
   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; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

   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. Degradation of rock and shotcrete due to ice pressure and frost shattering

   University dissertation from Luleå : Luleå tekniska universitet

   Author : Anna Andrén; [2009]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Geoengineering and mining engineering; Samhällsbyggnadsteknik och arkitektur - Geoteknik och gruvteknik; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : In recent years the Swedish Rail Administration has observed an increased incidence of shotcrete and rock fall-outs in its tunnels, for which reason it has initiated several research projects, of which the present project entitled "Degradation of rock and shotcrete due to ice pressure and frost shattering" is one. The aim of this licentiate project was to bring together experience and information relating to ice formation and the effect of ice pressure on fault zones, cracks and, in particular, the shotcrete/rock interface.

5. 3. Deformation and failure of hard rock under laboratory and field conditions

   University dissertation from Luleå : Luleå tekniska universitet

   Author : Kelvis Pérez; [2009]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Geoengineering and mining engineering; Samhällsbyggnadsteknik och arkitektur - Geoteknik och gruvteknik; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : The understanding of the fracture mechanisms and failure processes of the rock is an important requirement for the design of mining excavations and civil engineering constructions. The fracture process is necessary for the excavation and fragmentation of rock, but fracture of rock must be avoided and controlled to preserve the integrity of the construction. READ MORE

6. 4. Load-Haul-Dump operations in underground mines

   University dissertation from Luleå : Luleå University of Technology

   Author : Bartlomiej Skawina; Jenny Greberg; Abubkary Salama; Oliver Langefeld; [2019]
   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.

7. 5. Strength, fallouts and numerical modelling of hard rock masses

   University dissertation from Luleå : Luleå tekniska universitet

   Author : Catrin Edelbro; [2008]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Geoengineering and mining engineering; Samhällsbyggnadsteknik och arkitektur - Geoteknik och gruvteknik; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : The prediction of compressive stress-induced failures is of concern for the design and construction of deep underground excavations in mining and civil engineering. An overstressed rock mass may result in fallouts of rock, which may cause occupational safety hazards, damage of equipment, and/or production disturbances. READ MORE
