    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. Design of Miniature Three-Phase Dump Load Model

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tiffany Salisbury; Muhammad Arsal Akram; [2022]
    Keywords : Hydropower; Dump load; Resistive load; Grid regulation;

    Abstract : In hydropower plants, a local load, also known as a dump load, could be installed to balance theelectrical grid by consuming excessive power. This enhances the dam safety. A design for asmall-scaled three-phase dump load is presented in this thesis. The designed model is built andevaluated through simulations and experiments. READ MORE

  4. 3. Path Following Model Predictive Control for Center-Articulated Vehicles

    University essay from Uppsala universitet/Signaler och system

    Author : Gustav Vallinder; [2021]
    Keywords : NMPC; MPC; nonlinear model predictive control; model predictive control; path following; mining vehicles.;

    Abstract : Increased safety and productivity are driving factors for the trend in the mining industry where equipment and machines increasingly get automated. An example is the load-haul-dump vehicle, which is a machine that is used for transport of ore in underground mines. READ MORE

  5. 4. Classication framework formonitoring calibration ofautonomous waist-actuated minevehicles

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Per Landström; John Sandström; [2020]
    Keywords : SVM; NDT; machine learning; scan matching; hinge angle sensor; calibration detection;

    Abstract : For autonomous mine vehicles that perform the ”load-haul-dump” (LHD) cycle to operate properly, calibration of the sensors they rely on is crucial. The LHD cycle refers to a vehicle that loads material, hauls the material along a route and dumps it in an extraction point. READ MORE

  6. 5. Evaluation of a digitial displacement pump in a load haul dump application

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jayasurya Madhusudanan; [2019]
    Keywords : Digital displacement pump; mine loader; energy efficiency; backward simulation; forward simulation; pump losses;

    Abstract : Hydraulics has always been the first choice of actuation in off-road, construction and mining vehicles due to its power density, low cost, built in cooling and lubrication. However, the current state of our environment along with stricter regulations has brought light to newer technologies within hydraulics to improve the existing system. READ MORE
