  1. 1. Factors that influence an LHD operation: A Review

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Ivan Ricardo Marin Rodriguez; [2023]
    Keywords : LHD; LHD Operation; LHD Design; Bucket Design; Loading Operation; LHD Productivity; Fragmentation; LHD Operator;

    Abstract : As an important sector of the global economy, underground mining serves as the foundation for the economies of many nations. It involves the extraction of precious minerals, ores, and other geological elements. READ MORE

  3. 2. Optimal Control and Thermal Managementof Heavy-Duty FCHEV Powertrains : Minimizing hydrogen consumption of an FCHEV using numerical optimal control and an integrated energy and thermal management system

    University essay from Linköpings universitet/Fordonssystem

    Author : Daniel Similä; Jonatan Siönäs; [2022]
    Keywords : Control Engineering; Powertrain Engineering; FCHEV; Optimal Control; Thermal Management;

    Abstract : The CO2 emissions from road vehicles must be reduced in order to avoid a 1.5 ◦C global warming. To reduce tailpipe emissions, a strong trend is to electrify powertrains to shift away from the use of fossil fuel. Among alternatives, the fuel cellhybrid electric vehicle (FCHEV) is seen as a promising configuration. READ MORE

  4. 3. Electrification of Heavy Transport Vehicles in Stockholm Sweden

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Joel Amb; Rikard McPherson; [2021]
    Keywords : ;

    Abstract : Sweden wants to reach its climate goals and one important step towards doing so is to lower road emissions. Today heavy transport constitutes 5% of all vehicles on the road in Sweden but are contributing to 25% of all CO2 road emissions. READ MORE

  5. 4. Monitoring energy efficiency of heavy haul freight trains with energy meter data

    University essay from KTH/Spårfordon

    Author : Philipp Geiberger; [2021]
    Keywords : Energy consumption; Energy meter; Energy monitoring; Heavy haul freight train; Key performance indicator; Multi-particle model; Simulation; Energiförbrukning; Elmätare; Energiuppföljning; Tungt godståg; Nyckeltal; Flerpartikelmodell; Simulering;

    Abstract : In this MSc thesis, it is investigated what parameters are relevant for describing energy consumption of heavy haul freight trains and how these can be used to develop key performance indicators (KPIs) for energy efficiency. The possible set of KPI is bounded by data available from energy meters used in electric IORE class locomotives hauling iron ore trains in northern Sweden. READ MORE

  6. 5. 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
