Purpose and goal

The objective of the proposed project is to increase production capacity and reduce production cost for Sublevel Caving mines by optimizing fragmentation, using optimized blast hole sizes, improved chargeability, new technique for boulder handling and improved overall production planning.

Expected results and effects

The project will develop production tools for material characterization for charging support. The project will also provide a deeper understanding of how hole sizes influence ground vibrations. The project will develop procedures for how production planning can be improved by better rock mass characterisation and generate a better and deeper understanding of how mobile boulder breakers can reduce production disturbances. The results from the project will include a licentiate thesis and a number of journal and conference papers.

Planned approach and implementation

The research methodology combines state-of-the-art investigation, machine monitoring, borehole filming and video recording, using data mining and big-data analysis, interviews and field tests. Regular meetings and workshops have been identified as an important tool for knowledge and information transfer.
