Pre-split blasting is a controlled blasting technique used in mining and construction to create a precise fracture plane in rock before the main blast, minimising overbreak and controlling the final wall shape. This method involves drilling closely spaced, parallel holes along the desired final rock face and lightly charging them to produce a clean, stable split in the rock.

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.

Blasting in mining and tunnelling involves the use of explosives to break rock and excavate materials. In mining, blasting is primarily used to fragment rock to extract valuable minerals, often requiring precise control to maximise ore recovery while minimising dilution and damage to the surrounding rock. In tunnelling, the primary objective of blasting is to create underground passages and spaces, necessitating careful design to ensure stability and safety of the tunnel structure. While both ap
