2. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction
Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE

3. Fragmentation and waste rock compaction in small-scale confined blasting
Abstract : Sub-level caving (SLC) is an important mass mining method, used at LKAB e.g. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses. READ MORE

4. Waste rock content variations during gravity flow in sublevel caving : analysis of full-scale experiments and numerical simulations
Abstract : När man lastar i en skivrasgruva så märker man ofta att gråbergshalten varierar på ett oregelbundet sätt. Denna variation är oönskad på grund av att den leder till gråbergsinblandning och malmförluster. READ MORE

5. Fractured Rock Masses as Equivalent Continua - A Numerical Study
Abstract : In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach.
