Blast Hole Drilling

Blast Hole Drilling

Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.

The initial hole into which the explosives are packed is known as the “blast hole”. Blast hole drilling is one of the primary surface drilling techniques employed in mining operations today.

Blast hole drilling is traditionally used wherever the mining company wants to explore the mineral composition or potential mineral yield of the area demarcated for their mining interests.

Blast holes are thus a fundamental step in the exploratory mining process, and can be employed in both surface mining operations and underground mining operations to varying degrees with varying effects or results.

Blast hole drilling can also be employed in quarrying endeavors.
