  5. 4. Borehole Dimension Impact on LHD Operation in Malmberget Mine

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Markus Danielsson; [2016]
    Nyckelord :LHD; sublevel caving; fragmentation;

    Sammanfattning : Sublevel caving is a highly mechanizable mass mining method normally utilized in large, steeply dipping orebodies. The fragmented ore flows freely, aided by gravity, down to the drawpoint while the surrounding waste rock caves in due to induced stresses and gravity. LÄS MER
