  1. 1. Electrification of rock drills : An initial study of an electromagnetic percussion concept

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jakob Smith Siljestrand; Sai Shridhar Chebolu; [2023]
    Keywords : Epiroc; electrification; Hopsan; TLPM; linear motor; rock drill; percussion; electromagnetic; simulation; electric motor; mining; electromagnetism;

    Abstract : The world is looking for greener solutions and so is the mining industry. This quest has led to the question whether it is possible to have a completely electric rock drill. This work carries out an initial exploration of completely electrified percussion. READ MORE

  3. 2. Modeling of a Hydraulic Rock Drill for Condition Monitoring

    University essay from Linköpings universitet/Fordonssystem

    Author : Adam Kagebeck; Mahdi Najafi; [2022]
    Keywords : Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

    Abstract : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. READ MORE

  4. 3. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs

    University essay from Linköpings universitet/Fordonssystem

    Author : Mohamed Faraj; Max Olsson; [2022]
    Keywords : Vehicle Propulsion Systems; Electrical powertrain; Modeling; Simulation; Deterministic dynamic programming; AMESim;

    Abstract : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. READ MORE

  5. 4. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Ioannis Peroulakis; [2022]
    Keywords : Drilling; MWD; Garpenberg; Mining; Geotechnics;

    Abstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

  6. 5. Digital twin of a safe system

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Johan Edenhamn; [2022]
    Keywords : digital twin; safe system; hardware-in-the-loop HIL ; hydraulic model;

    Abstract : At Epiroc’s drill rigs a safe system is installed to make sure the vehicle is driven in a safe manner. In the development both machine tests and hardware-in-the-loop (HIL) tests have been performed but when changes are made the firmware in the safe modules has to be updated. To speed up the process a digital twin would be beneficial. READ MORE
