... under both quasi-static (e.g. uniaxial compression) and dynamic (e.g. rock blasting) loading conditions. However, the most challenging part in the application of the original Y-HFDEM code was its simulation time required to solve large-scale problems with massive number of nodes, elements and contact...

... Abstract The three most predominant methods for hard rock excavation and fragmentation are the use of explosives, mechanical impact/cutting and hydraulic fracturing. However, those methods have inherent drawbacks, such as non-applicability or poor performance in extremely hard and abrasive...

... Abstract The use of mobile scanning devices is increasing within the underground mining industry, specifically for geomechanics applications. These devices allow rapid data acquisition and the spatially-continuous monitoring of excavations in GPS-deprived environments. The data, when analysed...
