Blasting in mining is a critical method used to extract valuable materials from rock formations. It involves the use of explosives to break up large volumes of rock, making it easier to transport and process. The process begins by drilling holes into the rock, which are then loaded with explosives. When detonated, the explosives create fractures in the rock, allowing the material to be extracted more efficiently. The principles of blasting in mining and tunnelling are quite similar, as both rely

The drill and blast method in mining involves drilling holes into rock, filling them with explosives, and initiating controlled detonations. An integral aspect of this process is the strategic use of detonation delay, where intentional pauses between explosive charges in different holes enhance the effectiveness of fragmentation. This technique ensures improved rock breakage, minimised ground vibrations, reduced flyrock, and optimised energy distribution. The calculation of delay times considers

Blasting is a crucial technique in mining, construction, and the excavation of pipelines in hard rock environments, as it uses controlled explosions to fracture and dislodge rock, making the removal process significantly easier and more efficient. It helps access ore deposits, clear rock for foundations and tunnels, and create trenches for pipelines, reducing labour, equipment wear, and costs while enhancing safety by precisely controlling rock breakage.
