  1. 6. Unmanned operation of load-haul-dump vehicles in mining environments

    Författare :Johan Larsson; Alessandro Saffiotti; Thomas Hellström; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and Systems Science; Datavetenskap;

    Sammanfattning : Underground mines typically do not represent the best working conditions for humans, and many mining companies have the intent to remove all humans from the ore extraction areas. To achieve this goal automation of the mining machinery is required. LÄS MER

  3. 7. Drill process monitoring in percussive drilling for location of structural features, lithological boundaries and rock properties, and for drill productivity evaluation

    Författare :Håkan Schunnesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : This thesis deals with the application of percussive drill monitoring in the mining and underground construction industries. The technique has been used to provide information on different ground properties and conditions and for drill productivity evaluation. LÄS MER

  4. 8. Deformation and failure of hard rock under laboratory and field conditions

    Författare :Kelvis Pérez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The understanding of the fracture mechanisms and failure processes of the rock is an important requirement for the design of mining excavations and civil engineering constructions. The fracture process is necessary for the excavation and fragmentation of rock, but fracture of rock must be avoided and controlled to preserve the integrity of the construction. LÄS MER

  5. 9. On Autonomous Deployment of Micro Aerial Field Vehicles

    Författare :Sina Sharif Mansouri; George Nikolakopoulos; António Pedro Aguiar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In this thesis, I am going to investigate the control, navigation and path planning frame-works forMicro Aerial Vehicles (MAVs), both mathematically and algorithmically. Inorder to deploy them in challenging real life applications and with a main focus on theunderground mine navigation and wind turbine inspection. LÄS MER
