    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

  5. 3. Mine Production Assurance Program- Development and Application

    University dissertation from Luleå : Luleå University of Technology

    Author : Amol Lanke; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : ssuring production forms a crucial part of mining business profitability. Factors related to various mine operations, activities and business processes can threaten required/planned mine production.   To address problems and ensure production level in mining, it is necessary to implement a mine production assurance program (MPA).

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anna Andrén; Luleå tekniska universitet.; [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.

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kelvis Pérez; Luleå tekniska universitet.; [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
