  4. 2. Caving mechanisms for a non-daylighting orebody

    Author : Sraj Umar Banda; Jonny Sjöberg; Björn Nilsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel caving; numerical analysis; laser scanning; seismic data; large-scale structure; rock mass characterization; failure mechanism; discontinuum modeling; continuum modeling; caving analysis; voronoi modeling; bonded block model; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass. READ MORE

  5. 3. Improved understanding of sublevel blasting : Determination of the extent of the compacted zone, its properties and the effects on caving

    Author : Nikolaos Petropoulos; Daniel Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sublevel mining; compaction; confining material; confined blast; impact tests; burden dynamics; coarse-grained material; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Sublevel caving (SLC) is a mass mining method relying on the flowability of the blasted material. The ore is blasted in slices against caved material which is mainly waste rock. The result of the confined blast is greatly influenced by the interaction between the blasted material and the caved material. READ MORE

  6. 4. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests

    Author : Daniel Johansson; Gideon Chitombo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. READ MORE
