  2. 1. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests

    Author : Matthias Wimmer; Pekka Särkkä; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. READ MORE

  4. 2. Draw control strategy for sublevel caving mines : A probabilistic approach

    Author : Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Matthias Wimmer; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control; sublevel caving; probability models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. READ MORE
