Open-field drilling covers drilling blast holes on benches and open ground in mining, construction and infrastructure projects as designed; hole diameter, depth, inclination and position determine blast success.
Scope
- Open-field drilling for mining, construction and infrastructure projects
- Hole diameter, depth, inclination and position applied as per the blast design
- Recording drilling parameters with MWD and monitoring changes in rock
- Integrated planning with our blasting services
Why does drilling quality matter?
Hole deviation disturbs the designed burden and spacing, which affects fragmentation, vibration and flyrock risk. A correctly drilled hole is the first condition of a controlled and efficient blast.
Frequently asked questions
Which projects use open-field drilling?
Open-pit mining, quarries, construction excavations and infrastructure projects use open-field drilling to prepare holes before blasting.
How does hole deviation affect blasting?
Deviation disturbs the designed hole layout and can lead to uneven fragmentation, higher vibration or flyrock risk.
Can drilling and blasting be provided by the same company?
Yes. Because we provide both drilling and blasting, hole design and blast plan can be handled together.
Why does hole diameter matter?
Hole diameter affects the amount of explosive that can be used and the hole spacing; it is selected according to rock structure and target fragment size.
