FAQ
What types of drilling rigs does DXG operate?
We operate Epiroc T40/T45 and Sandvik DX700/DX800 top hammer rigs, ideal for quarry and infrastructure applications across a range of rock types.
What is Measured While Drilling (MWD)?
MWD is a technology that records real-time data during drilling, such as penetration rate and rock hardness. It improves blast planning and provides valuable geotechnical insight.
Are your drills GPS-enabled?
Selected drills are fitted with GPS systems to ensure accurate delivery of computer optimised blast design with precise hole location, depth, and spacing, resulting in better fragmentation and fewer blasting issues.
What regions do you service?
DXG operates nationwide across New Zealand, with the ability to mobilise quickly to remote or regional quarry sites.
Can DXG provide drilling for civil infrastructure as well as quarry sites?
Absolutely. Our equipment and operators are also suited for infrastructure drilling, including investigation drilling, blast holes, pre-split work alongside civil contractors.
