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

The drill and blast method holds a pivotal role in mineral extraction from the ground, serving as a cornerstone for industrial development. This technique involves drilling holes into the ground and then strategically placing explosives to break apart the rock, allowing for the retrieval of valuable minerals. Its significance lies in its efficiency and versatility, enabling access to mineral deposits that would otherwise remain inaccessible. We have covered drill and blast method in tunnelling a
