TECHNICAL SERVICS
OVERVIEW
DXG provides a comprehensive suite of technical blasting services, delivered by experienced engineers and consultants with proven capabilities across all aspects of blast design, vibration analysis, and project management.
Whether for quarrying, civil construction, or mining operations, DXG supports clients with both in-house expertise and access to a trusted network of external blasting consultants. Our goal is to help you plan and execute safe, compliant, and cost-effective blasting operations—no matter the scale or sensitivity of the project.
OUR TECHNICAL SERVICES INCLUDE:
1. Drone Surveying & Pit Modelling
We use high-resolution drone photogrammetry and 3D pit modelling to assess site conditions and plan accurate, data-informed blast designs. This enables better volume estimation, burden analysis, and blast sequencing. This can tie directly into pit shell design to NZ guidelines.
2. CAD-Based Blast Design
Our team develops precision CAD blast designs that take into account geological conditions, safety margins, vibration thresholds, and project constraints—supporting optimal fragmentation and minimal environmental impact.
3. MWD Processing & Analysis
We offer Measurement While Drilling (MWD) data processing to gain deeper insight into rock conditions. MWD analysis helps fine-tune charging strategies and improve overall blast performance and consistency.
4. Vibration Monitoring & Control
DXG specialises in blast vibration monitoring, analysis, and predictive modelling to meet environmental and regulatory limits. We mitigate risks to nearby structures, and ensure compliance with consent conditions.
5. Blast Vibration Optimisation
Through on-site review and data-led adjustment, we support the optimisation of blast parameters to balance performance, safety, and compliance—especially in sensitive or urban areas where ground vibration is critical.
6. Feasibility Analysis & Risk Assessment
We conduct detailed blasting feasibility studies, including environmental risk analysis, commercial evaluation, and compliance readiness. This service helps clients understand the viability of blasting on challenging or regulated sites.
7. Environmental and Consenting Support
Our team can assist with peer review, technical reporting, and support for blasting consents or resource applications—ensuring smooth navigation of local regulatory frameworks.

FAQ
What industries does DXG support with blasting technical services?
We support clients in the mining, quarrying, and civil construction sectors, including projects in sensitive or highly regulated areas.
Can DXG help with peer review and compliance documents?
Yes. We offer peer review services and can prepare or contribute to consenting / compliance documentation, including principal hazard management plans (explosives aspects), drilling and blasting management plans and vibration / environmental assessments relating to drill and blast.
What is MWD and why is it important?
Measurement While Drilling (MWD) collects rock drill data and infers rock characteristics . This helps improve blast optimisation, charge control, and fragmentation outcomes by adapting to real-time ground conditions.
How can drone surveying improve blasting outcomes?
Drone surveying provides high-resolution site models that support accurate burden calculations, pit geometry, and more effective blast planning—all while improving safety by reducing onsite exposure.
Do you provide on-site vibration monitoring?
Yes, DXG can deploy vibration monitors pre-, during, and post-blasting, and provide analysis to ensure compliance with site-specific limits and minimise impact on nearby structures or receptors.
