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

   Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Linköpings universitet/Optimeringslära; Linköpings universitet/Tekniska fakulteten

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

   Sammanfattning : 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. LÄS MER

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

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

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

   Sammanfattning : 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. LÄS MER

5. 4. A framework for traffic management and collision avoidance in underground mines

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

   Författare :Mikaela Åhlén; [2014]
   Nyckelord :;

   Sammanfattning : Mining is an ancient occupation and the purpose is to access and extract minerals in the ground, which after being brought to the surface can be processed and sold at a profit. A mine, especially when active, is a dangerous place; mine collapse and other accidents have over the years claimed many lives. LÄS MER
