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. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting

   Author : Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Philipp Hartlieb; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement while drilling; Photogrammetry; Rock fragmentation; Gruv- och berganläggningsteknik; Mining and Rock Engineering;

   Abstract : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. READ MORE

5. 3. 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

6. 4. Interaction between shotcrete and rock : experimental and numerical study

   Author : Lars Malmgren; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : At LKAB’s underground mines in Malmberget and Kiruna in northern Sweden shotcrete and rock bolts are the main rock support elements. A safe working environment for the miners and high accessibility to the mine are important issues. READ MORE

7. 5. Controlled fragmentation and contours in rock blasting : theoretical and technical approaches

   Author : Agne Rustan; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The Swedish mining and construction industries have a large interest in improving blasting technology, in milling concerning rock fragmentation by blasting (especially underground in large diameter hole blasting, > 100 mm) and in construction and mining concerning controlled and safe contours in blasted tunnels. This doctoral thesis deals with these matters and includes a licentiate thesis (published in 1970) and five papers A-E included in the doctoral thesis and published during 1983 to 1992. READ MORE
