1. Burden Dynamics and Fragmentation
Sammanfattning : Drill and blast is a dominant technique in several surface and underground mines in the world. The purpose of this technique is to break rock mass into fragments, which can be handled by mining equipment. The identified major influencing factors in rock blasting are stress waves and gas pressurization. LÄS MER
2. Improved understanding of sublevel blasting : Determination of the extent of the compacted zone, its properties and the effects on caving
Sammanfattning : 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. LÄS MER
3. Small-scale Experiments for Blast-induced Damage: Exploring crack propagation through Digital Image Correlation
Sammanfattning : Blasting plays a crucial role in several engineering applications, from mining and tunneling to demolition projects. One of the remaining challenges of this process is that it can significantly affect the integrity of the rock mass by inducing damage in the form of cracks. LÄS MER
