Open Pit Engineering Consultants — Australia

Pit shell, phase and access design

• Economic shell selection and phase optimisation with ramp geometry and switchbacks
• Bench and berm standards, catch capacity and access maintenance strategy
• Alignment of phase sequence to crusher and plant constraints for value delivery

Haul roads and waste dump engineering

• Greenfield and brownfield haul road alignment, gradients, crossfalls and intersections
• Rolling resistance management: drainage, surfacing, maintenance windows and KPIs
• Waste dump siting, lift sequencing, landform geometry and progressive rehabilitation interface

Drill and blast engineering

• Pattern design, burden/spacing, subdrill, timing and tie‑ins for fragmentation and wall control
• Powder factor optimisation with cost/fragmentation trade‑offs and vibration management
• QA/QC workflows, exclusion planning and reconciliation to dig/break/throughput

Load and haul productivity and fleet

• Truck–shovel match studies, cycle time diagnostics, queueing and dispatch alignment
• Haulage modelling with speed profiles, grades and rolling resistance calibration
• Fleet selection/expansion options with TCO comparisons and scenario testing

Short and medium‑term planning

• Bench‑by‑bench plans aligning drill, blast, load and haul to plant requirements
• Short interval control workflows integrated with fleet data and compliance dashboards
• Plan vs actual reconciliation with root‑cause analysis and action tracking

Studies, approvals and enablement

• Scoping/PFS/DFS inputs: design criteria, execution strategies, risks and assumptions
• Independent readiness reviews before gate submissions or investment committees
• Selection/configuration of scheduling, fleet and reporting systems with training

Haul road realignment uplift

Alignment changes, grade control and rolling resistance management cut cycle time variance and lifted effective truck hours without adding fleet.

Drill and blast optimisation

Re‑balanced burden/spacing and timing improved crusher throughput while maintaining vibration limits near infrastructure.

Phase redesign and access

Re‑sequenced phases preserved ramp geometry, smoothed waste stripping and improved NPV under plant and haulage constraints.
