Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions. Hand-drilled holes seldom exceed 400mm in length.

the mining sector, drilling blasting operations are being conducted through more strategic avenues. Mining companies recognise the need to improve analysis of site data, select appropriate tools and technologies, achieve higher fragmentation and improve exclusion zone management.

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.

Drill and blast method is mostly used method for the excavation throughout the world. The method can be used in all types of rocks and the initial cost is lower than the mechanical method like TBM. This tunneling method involves the use of explosives. Compared with bored tunneling by Tunnel Boring Machine, blasting generally results in higher duration of vibration levels. The excavation rate is also

The process involves drilling several holes into the rock and filling them with explosives. The locations and size of these holes are carefully determined by mining engineers based on geological surveys, as well as the quantity of explosives. When detonated, these explosives cause the rock to collapse. Detonations are precisely patterned and timed to have the desired effect.
