  1. 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; Luleå tekniska universitet.; [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

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jeroen van Eldert; Luleå tekniska universitet.; [2018]
    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

  3. 3. Interaction between shotcrete and rock experimental and numerical study

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars Malmgren; [2005]
    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

  4. 4. Controlled fragmentation and contours in rock blasting theoretical and technical approaches

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Agne Rustan; [1995]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    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

  5. 5. Rock fragmentation by cutting, ripping and impacts : some theoretical and experimental studies

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Karl Erik Rånman; [1986]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Abstract : Models of different forms of rock fragmentation are presented, having mainly two purposes; to increase the understanding for the fragmentation processes, and to form a base for quantitative predictions. The results of some full scale rock cutting tests are also presented. The thesis consists of five separate papers. READ MORE
