Blast Design, Vibration Monitoring & Technical Blasting Services NZ

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Experienced technical services staff with strong capabilities in all aspects of blast design, vibration and project management, peer review and consenting support.

OVERVIEW

DXG provides specialist blasting consultancy services across New Zealand, including blast design, vibration monitoring, drone surveying, and consent support. Our experienced engineers and consultants help quarrying, mining, and civil contractors plan and execute safe, compliant, and cost-efficient blasting operations.

Whether you’re working on a quarry, transport corridor, or vibration-sensitive urban site, DXG combines in-house expertise with access to a trusted global network of consultants — ensuring every project benefits from the latest technology, data, and industry best practice.

OUR TECHNICAL SERVICES

1. Drone Surveying & 3D Pit Modelling

High-resolution drone photogrammetry and 3D blast modelling provide accurate burden analysis, volume estimates, and pit designs to NZ guidelines. This ensures data-driven decision-making for safe and efficient blasts.

2. CAD-Based Blast Design

Our team develops precision blast designs in CAD, accounting for geology, vibration limits, safety margins, and environmental factors. Optimised designs deliver better fragmentation, reduced vibration, and controlled outcomes.

3. MWD Data Processing & Analysis

Through Measured While Drilling (MWD) analysis, we capture rock condition data in real-time. This supports charging strategy optimisation and improves consistency across multiple blasts.

4. Vibration Monitoring & Control

DXG provides on-site blast vibration monitoring services, predictive modelling, and mitigation strategies. We ensure compliance with regulatory vibration limits while minimising risks to nearby structures, utilities, and communities.

5. Blast Optimisation

Our engineers use performance data to fine-tune blasting parameters, balancing fragmentation, vibration, and cost-effectiveness — especially for sensitive or urban blasting environments.

6. Feasibility Studies & Risk Assessment

We conduct detailed blasting feasibility studies and risk assessments, including environmental impact analysis, commercial evaluation, and compliance readiness.

7. Environmental & Consenting Support

DXG assists with peer reviews, compliance reporting, and blasting consent applications, providing councils, clients, and contractors with the technical assurance needed for regulatory approval.
