Core Services
Technical Drill & Blast Audits
Drill and blast audits are often the first step towards improving performance. Hedardh provide independent technical drill and blast audits reviewing current blasting practices, equipment utilisation, design controls, explosives performance, and compliance standards. Our audits are tailored to the specific site requirements and cover (but are not limited to) the following areas:
- Identification of productivity improvement areas
- Review of blast efficiencies, explosives and initiation systems
- In-depth design reviews – final wall, development and production blasting
- Safety and regulatory compliance overview
- Blast crew, engineering and equipment utilisation reviews
- Explosive performance measurements
Blast Performance & Optimisation
Blast performance and optimisation services improve the interaction between blast design, geology, geotechnical, mineral processing, and operational productivity. We can help sites achieve safer blasts, better mill performance, reduced costs, and more predictable production outcomes.
- Mine to mill studies
- Geotechnically driven wall control blast design
- Ore dilution improvements
- Fragmentation improvements, productivity gains, and cost reduction
- Explosives and initiation system optimisation
Technical Assurance & Risk Management
Technical assurance and risk management provides independent support to ensure drill and blast activities are controlled, compliant, and resilient to operational hazards. Our services include reviewing procedures, investigating incidents, assessing explosives quality, and supporting specialist risk areas such as misfires and reactive ground conditions.
- Operational compliance reviews & risk assessment
- Misfire investigation, incident reviews, and regulatory liaison
- Explosives quality assessments
- Hot & reactive ground management
Environmental & Regulatory Support
Environmental and regulatory support helps operations manage the impacts of blasting while maintaining compliance with licencing, planning, and stakeholder requirements. Our service includes vibration and air overpressure monitoring, impact assessment, equipment supply, and clear communication with regulators, residents and project stakeholders.
- Blast vibration and air overpressure monitoring and management
- Vibration and AOP monitoring equipment supply
- Environmental impact assessment and mitigation strategies
- Regulator engagement and planning condition support
- Structural damage assessment
- Neighbour liaison services
Advisory & Capability Development
Our advisory and capability development supports clients from early-stage feasibility studies through to project execution and operational team development. This service provides practical technical guidance, due diligence, contract support, mentoring, and training to strengthen internal capability and improve long-term drill and blast performance. Contractor assessment and tender support is also available.
- Feasibility studies and technical due diligence
- Project support from concept through to execution
- D&B contract evaluation and management
- Training, mentoring, and competency development for engineers and operational teams
- Initiation system and explosive use and application training
