There are lots of drilling applications in tunnel works, including drilling for blast holes, pregrouting, rock reinforcement etc. Each type of drilling application has its own demands on precision and accuracy. Drilling and blasting is used for rock tunnel excavation. It’s involves drilling charge hole advancing into rocks and using explosives to blast the rocks.

With good control on the drilling and blasting it is possible to get a good result of the size fractions. The purpose with pre grouting is to seal and stabilize the rock mass in front of the face. Drilling also is used for rock reinforcement to provide a safe working environment for continuous excavation, it normally includes spot bolting, and forepoling, or providing long term support for a life-span of tunnel it normally includes shotcrete and rock bolts.
