  1. 1. Automated Scheduling of Mining Operation Tasks

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : David Olsson Granlund; [2021]
    Keywords : automated scheduling; mine scheduling; scheduling; constraint programming;

    Abstract : The task of scheduling mining operations is a strikingly tough task yet it is still largely done manually by hand or with the help of simple gantt planning tools. This thesis aim is to explore the feasibility of an automatic scheduling solution that can incorporate the constraints specific to mining operations. READ MORE

  3. 2. Scheduling of an underground mine by combining logic based Benders decomposition and a constructive heuristic

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Emil Lindh; Kim Olsson; [2021]
    Keywords : Underground mine scheduling; Cut-and-fill mining; Logic-based Benders decomposition; Constructive heuristic;

    Abstract : Underground mining is a complex operation that requires careful planning. The short-term scheduling, which is the scheduling of the tasks involved in the excavation process, is an important part of the planning process. READ MORE

  4. 3. Optimisation of hauling schedules and passing bay locations in underground mines using a time-discrete mathematical model

    University essay from Linköpings universitet/Optimeringslära; Linköpings universitet/Tekniska fakulteten

    Author : Albin Ryberg; [2020]
    Keywords : Scheduling; Optimisation; Underground Mining; Transportation; Time-Discrete; Mixed-Integer Programming.;

    Abstract : The ambition of this project is to contribute to the development of optimisation techniques for underground mining. This resulted in a mathematical model to optimise a type of underground transportation system called the ramp. The ramp is a tunnel from the underground mining areas which trucks use to transport material up to the surface. READ MORE

  5. 4. Predictive Model for Traffic Control in Underground Mines

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Claes Andersson; [2019]
    Keywords : underground; mine; tunnel; traffic; control; management; collision avoidance; single track; velocity; prediction; distribution;

    Abstract : Due to the nature of tunnels, a driver in an underground mine may find themselves driving without much vision of the road up ahead. The tunnels usually allow for traffic in both directions but are often only wide enough for a single vehicle. READ MORE

  6. 5. Medium term planning with Evolution : Comparison with current method at LKAB Svappavaara

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Koen Vos; [2018]
    Keywords : mining; production scheduling; mine planning;

    Abstract : This thesis looks at the medium term mine planning process and tools in the Leveäniemi open pit mine operated by LKAB Svappavaara. The current planning process uses software, Chronos, which was previously used successfully to perform medium term planning for the Gruvberget mine, which is also operated by LKAB Svappavaara.
