  1. 1. 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.

  3. 3. Footwall stability in SLC mining

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mikael Svartsjaern; David Saiang; Andreas Eitzenberger; Doug Stead; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : This thesis is based on a case study of the Kiirunavaara sublevel cave (SLC) mine. It focuses on footwall stability and damage development in the mining infrastructure on mine scale. Damage to the infrastructure is mappable for the full height of the footwall by access through decommissioned infrastructure associated with earlier mining stages. READ MORE

    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
