Pre‐mining depressurizing of a deep ore body at the McArthur River mine, the largest single producer of uranium in the world, was considered to decrease the risk associated with mining and increase the ground stability and the amount of ore that could be extracted. The challenge was to depressurize the high‐grade ore bodies without propagating a significant amount of drawdown to the surface where impacts on surface‐water resources and the associated aquatic habitat would be significant environmental issues. The objective was to evaluate the technical and economic feasibility of depressurizing the ore body.
Mikael Svartsjaern holds a PhD in Mining and Rock Engineering from Luleå University of Technology. The thesis work was performed in close collaboration with the mining company LKAB focusing on footwall stability and infrastructure damage at the Kiirunavaara mine. Mikael has practical mining experience from underground mapping and is well acquainted numerical modelling in 2D and 3D. He also has teaching experience on both basic and advanced level in rock mechanics from his University years.
