  1. 1. 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

  3. 2. Smart components : Creating a competitive edge through smart connected drive train on mining machines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : KAJOL SINGH; [2021]
    Keywords : Drivetrain; downtime; sensor system; operating data; planned maintenance; spare parts inventory; Drivlina; stillestånd; givarsystem; driftsdata; planerat underhåll; reservdelsinventering;

    Abstract : Major drivetrain components of the Epiroc machines like axles, gearboxes, transmission, torqueconverter, clutch, and bearings are critical components which are focused upon in this thesis. Failure of these major component results in breakdown of the vehicle and if early fault detection is not existing, then this causes engineers and technicians to spend a substantial amount of time to identify the root cause of the failure.

  4. 3. Development and application of a tool for assessing the impact of failure modes on performance of underground drill rigs.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Rickard Larsson; [2021]
    Keywords : availability; functional contracts; failure modes; discrete event simulation; mining; drilling rigs; tillgänglighet; funktionella kontrakt; feltillstånd; diskret händelsestyrd simulering; gruvdrift; borriggar;

    Abstract : Trends such as increasing awareness of sustainable production, shorter product life cycles and personalised products create challenges for the mining industry. A solution to these challenges may be a functional product business model, where the provider sells the hardware’s function under a service contract and is responsible for delivering the combination of hardware and services over the duration of the contract.
