  1. 1. Investigation of Influential Contexts on Mining-front Seismicity at Kiirunavaara Mine

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Bernardo Filizzola; [2023]
    Keywords : ;

    Abstract : Mining at great depths has become the reality for the mining industry in Sweden, that faces challenges in terms of increasing seismic events and sometimes intrinsically related rock mass failure. Kiirunavaara mine is owned by LKAB (located at north Sweden) and the company has been dealing with seismicity in a daily basis once the mine has been regarded as seismically active since 2007-2008 and presently has the largest seismic monitoring system in the world.

  2. 2. Stress dependent flow behavior in sublevel caving mines

    University essay from KTH/Jord- och bergmekanik

    Author : Linde Mattsson; [2022]
    Keywords : level caving; Material Flow; Mining; Discrete element modeling.;

    Abstract : Sublevel caving is an underground mass mining method that utilizes the gravity-induced material flow for ore extraction. The granular flowbehavior is one of the main phenomena describing this mining method’s efficiency; therefore, a good understanding of the flow behavior is essential. READ MORE

  3. 3. Modular Communications Relay for Autonomous Quarry Operation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Simon Knutsson; Daniel Larmark; [2018]
    Keywords : Automation; Communications platform; Quarry; Open-pit mining; Construction Equipment; Automation; Kommunikations plattform; Bergtäkt; Gruvindustrin; Bygg-och Anläggningsutrustning;

    Abstract : Today’s quarries face a change in the operational processes, where the development of automated transport systems and machines have intensified the necessity for reliable and stable data transfer. Within the dynamic environment, with piles building up suddenly, frequently changing mining faces due to blasting, as well as a frequently changing general environment that affect the network coverage negatively, there is a need for a solution that can adapt to the changing environment.

    Abstract : Load, haul and dump machines (LHDs) are commonly used in underground mines around the world. The machines are used to transport fragmented ore after blasting in the ore body. The main propellant used is diesel which accounts for a large part of the diesel consumed in mines today. READ MORE

  5. 5. Design of a Mobile Pump Sump

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Texas Melander; [2016]
    Keywords : ;

    Abstract : Vid gruvdrift krävs det att grundvattnet pumpas undan och det görs med hjälp av ett system av pumpar placerade i utsprängda sumpar där vatten samlas. Dessa gropar är stora och dyra att tillverka och de lider ofta av problem med sedimentering. READ MORE
