$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.

Drill and blast method is one of the common tunnelling techniques in hard rock. The principle behind the blasting in tunnel is to create a free face at the centre of the tunnel by means of cut holes and then extending the blasting to the full face of tunnel. In simple words, blasting relies on two main factors: 1. shock wave to create cracks in the rock 2. Expansion of gas to move into the cracks to crush the rock. In our online Tunnel Engineering course, you will learn blasting techniques in tu

The drill and blast method is a widely used technique in mining operations, particularly in hard rock mining. This process involves two key components: drilling holes into the rock formation and subsequently blasting the rock to facilitate its fragmentation. Drill patterns are meticulously designed to optimise the blasting process, considering factors like rock type, size, and desired fragmentation. The drilling phase utilises specialised equipment to bore holes into the rock, where explosives a

Blasting mats are key when working close to structures or roads. They keep the blast contained, prevent flyrock and suppress dust at the job site. Our mats are made from old semi truck tire tread and weigh between 2000 to 3000 pounds. #construction #rockblasting #innovationinconstruction #dronesinconstruction #dronefootage #whateverittakes | McCallum Rock Drilling
