Geohazard Engineering

Mining Geohazard Services

Engineered geohazard solutions for New Zealand's mining and quarry sector — from highwall stabilisation to access road repair, deployed fast when operations are at risk.

MINING GEOHAZARD SERVICES

Mining operations in New Zealand place significant demands on geotechnical engineering. Open cut mines require stable pit walls engineered to manage the competing pressures of maximum ore recovery and acceptable slope stability risk. Underground operations require ground support systems that protect workers and maintain access throughout the life of the excavation. Both settings involve complex geology, significant consequence if things go wrong, and the operational reality that geohazard events directly affect production and safety.

GeoStabilization New Zealand Ltd provides geohazard mitigation and ground engineering services to the New Zealand mining sector. Our geotechnical engineers have experience in both open cut and underground environments, and our construction crews have the equipment and expertise to work within the health, safety and operational constraints that mining clients require. GSI NZ holds SiteWise Gold accreditation and carries out all work under site-specific health and safety plans that meet the requirements of major New Zealand mining operators.

APPLICATIONS

  • Open cut pit wall stability assessment and repair: slope stability, rockfall mitigation, and drainage improvement on exposed faces
  • Rock bolting, ground support installation, shotcrete and mesh surface support
  • Portal and adit stabilisation; ground improvement above underground workings
  • Emergency response to slope failures and ground movement affecting production and access

GSI NZ CAPABILITY

  • Experience across West Coast coal, Otago and Coromandel gold, and aggregate operations throughout New Zealand
  • SiteWise Gold accredited, with all works delivered under site-specific health and safety plans meeting the requirements of major NZ mining operators
  • Purpose-built compact equipment for steep terrain and remote mine sites; IRATA rope access crews for high-angle highwall work
  • 24/7 emergency response and no-cost, no-obligation site assessments for mining and quarry clients across New Zealand

THE GSI DIFFERENCE

ONE TEAM.
ONE CONTRACT.

  • Purpose-built compact equipment designed to reach steep terrain and remote mine sites; IRATA rope access crews for high-angle highwall work with no access road required.
  • Design/build under one contract — the same engineers who assess the hazard design the solution and supervise installation. No split accountability between designer and builder.
  • 24/7 emergency response capability. No-cost, no-obligation site assessments for mining and quarry clients across New Zealand.

HOW WE APPROACH MINING GEOHAZARD SERVICES

Step 1

Geohazard Assessment

We characterise the geohazard (whether rockfall, highwall instability, access road failure, or embankment distress) and advise on immediate risk management and permanent remediation options. Site visits are available at no cost and no obligation.

Step 2

Engineered Solution

Solutions are designed to meet the specific operational and safety requirements of your site. Typical approaches include highwall drilling and reinforcement, rockfall barrier installation and scaling, access road slope stabilisation, micropile foundations for mine infrastructure, and drainage improvement.

Step 3

Rapid Deployment

Our purpose-built equipment is designed for difficult-access and remote sites. We mobilise fast to active geohazard events and carry out works with minimal production disruption. Full QA documentation and as-built records are provided on completion.

CAPABILITY

Mining Geohazard Capability

GSI NZ's core capabilities (high-angle drilling, compact equipment, IRATA rope access, and design/build delivery) are directly applicable to mining geohazard challenges. Our experience on remote and restricted-access sites across New Zealand means we can reach and work on the difficult terrain that characterises many NZ mining operations.

Our geohazard engineering record includes emergency response to some of New Zealand's most significant events (the 2016 Kaikōura earthquake and Cyclone Gabrielle), where rapid deployment and compact equipment were the critical factors. The same model applies directly to mining geohazard events where production downtime cannot wait for conventional procurement.
