Underground Construction and Tunnelling
Drilling, charging and blasting productivity
Driving efficiency and progress by maintaining blasting schedules and reducing costs to unlock downstream benefits.
Drilling, charging and blasting productivity.
Drilling, charging and blasting productivity.
Underground construction and tunnelling projects depend on consistent, predictable drill and blast cycles. When drilling, charging, and blasting are not aligned, small inefficiencies can quickly impact schedules, increase costs, and disrupt downstream activities.
Orica’s drilling, charging and blasting productivity solution is designed to maintain blasting schedules, reduce drill and blast costs, and deliver consistent progress in complex underground environments. By combining reliable delivery systems, proven blasting technologies, and technical expertise, we help you improve execution where it matters most—at the face.
- Maintain consistent blasting schedules
- Reduce disruptions to development cycles
- Improve coordination between crews and activities
- Protect overall project timelines

Are delays in drilling, charging or blasting impacting your development schedule?
Accurate charging in confined environments
Reliable underground delivery systems ensure precise explosive placement in drives, stopes and confined tunnelling environments, improving blast consistency and performance.
Improved charge-up crew productivity
Streamlined charging processes enable better utilisation of crews and equipment, reducing time lost to inefficiencies and increasing productive shift time.
Reduced drill and blast costs
Efficient execution, improved logistics and consistent charging practices help reduce cost per metre while maintaining performance.
Increased drilling capacity
Optimised blast design and charging practices support pattern expansion, enabling greater development potential without compromising outcomes.
