1. 1. Rock Evaluation Using Digital Images and Drill Monitoring Data : Before and after rock blasting

   Författare :Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Philipp Hartlieb; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement while drilling; Photogrammetry; Rock fragmentation; Gruv- och berganläggningsteknik; Mining and Rock Engineering;

   Sammanfattning : This research is carried out to better understand the nature of the rock mass and to have a better anticipation of rock fragmentation before blasting the rock mass. Current practices of assessing rock mass usually involve techniques that focus on the surface or outcrop of the rock mass such as scanline surveys, window surveys, photogrammetry and laser scanning etc. LÄS MER

3. 2. Role of Fragmentation at the Production Level of a Sublevel Caving Operation

   Författare :Sohail Manzoor; Anna Gustafson; Håkan Schunnesson; Daniel Johansson; Javad Barabady; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : This research was conducted to evaluate the association of rock fragmentation with different unit operations of a sublevel caving (SLC) production cycle. Drilling, charging, and blasting, as well as the nature of the rock mass, can affect the fragmentation observed at the drawpoints. LÄS MER
