4. Drilling & Blasting Coordination

• Plan and supervise drilling activities (patterns, depths, and spacing) in line with technical standards.
• Coordinate with authorized blasting personnel to ensure safe, effective operations, assessing fragmentation, vibration, and fly-rock.
• Provide technical recommendations to improve blast performance while minimizing rock losses and safety hazards.

5. Rock Quality & Product Control

• Monitor granite quality/characteristics and classify materials according to production specifications.
• Oversee feed material supplied to crushing plants and investigate quality variations to ensure aggregate products meet client standards.

6. HSE, Risk & Environmental Management

• Promote a strong safety culture and conduct hazard assessments, wall/pit stability inspections, and toolbox briefings.
• Support dust, noise, waste, water, and fuel risk mitigation along with land rehabilitation and environmental compliance.
• Immediately report unsafe ground conditions, hazards, near-misses, or environmental incidents.

7. Fleet Optimization & Technical Reporting

• Work with management to optimize utilization of excavators, loaders, dump trucks, drill rigs, and crushers.
• Prepare daily, weekly, and monthly technical reports, production statistics, maps, and geological documentation.
