Build a Schedule. The Shift Team Will Actually Execute.
A heading goes down Tuesday. Your reschedule needs to run and week's schedules are due Wednesday. idoba.sim lets you re-run the revised schedule against your mine network, sequences, and fleet interactions before you commit the crew. Stop the mid-week scramble. Stress-test your weekly schedules before it leaves the office.
Winner, 2025 Mining Technology Excellence Award.
Optimise Before You Commit.
Reschedule Fast When Plans Change.
idoba.sim covers the full underground operating cycle for portal-access hard rock mines, from development advance and ground support through to load-and-haul across 14 shifts. You can model how those activities interact before the schedule is executed underground. No simulation experience required.
Stop the Mid-week
Scramble.
A ground support delay. An equipment breakdown. Conditions underground change mid-week and when they do, your reschedule and next week's schedules are due at the same time. idoba.sim lets you re-enter the revised sequence, run the scenario, and confirm whether the new target holds before it leaves the office.
Surface Bottlenecks Before the Shift Starts.
If too much activity is concentrated in one area of the mine, the congestion shows up in your shift data, not in your planning software output. By then it's too late. idoba.sim surfaces overloaded access routes, queuing points, and equipment conflicts before you commit the crew. Hand the Shift Supervisor a schedule they can work with.
Build a Schedule That Holds Up to Scrutiny.
Getting drill and blast, ground support, the Underground Manager, aligned on a single plan takes time you don't have. idoba.sim produces scenario outputs your whole team can read without a simulation background, so sign-off conversations are driven by simulation data rather than assumptions and fixed rates.
SIMULATION USE CASE
Benefits of a Dedicated Stockpile.
Adding a stockpile changes how every truck, loader, and shift sequence interacts underground. The question isn't whether a stockpile helps in theory. It is whether it helps enough in your mine.
In a recent study, idoba.sim was used to model the impact of a dedicated stockpile in an underground hard rock operation, examining total material moved, ore tonnes delivered to surface, truck productivity, and shift transition performance across the P10/P50/P90 range.
The simulation showed how stockpile placement affects load-and-haul interactions, shift changeover efficiency, and overall ore delivery, giving the planning team the evidence to make the capital case before committing.
12%
Increased Primary Ore Throughput.
39%
Increased Loader Utilisation.
The Schedule was Ready. Then Tuesday’s Re-schedule Landed.
idoba.sim closes the gap between what your weekly schedule promises and what actually executes underground, running every truck, loader, and jumbo as an independent agent before crews are committed.
RAPID RESCHEDULE
A ground support delay at one heading. An equipment breakdown that reshuffles the sequence. Conditions underground change constantly, and when they do, the consequences ripple through equipment interactions, infrastructure access, and activity timing in ways rate based tools often miss.
idoba.sim lets you re-run the revised schedule against the mine network and fleet. Test whether the new heading sequence still delivers the weekly targets. Confirm the revised fleet allocation holds across all 14 shifts.
Reschedule. Recover Fast. Hit Your Weekly Targets.
SCENARIO ANALYSIS
Optimise Before You Commit the Schedule.
idoba.sim runs 25 statistically varied simulations per scenario, producing a distribution of outcomes, P10/ P50/ P90 modelled against your mine network.
Visual data showing where fleet interactions drive the gap between the schedule and what executes underground. Scenario comparisons you can present to the team without a simulation expert in the room. Run the scenario. Choose the configuration, commit your weekly schedules with confidence.
BOTTLENECK IDENTIFICATION
See Where Throughput is Lost Before the Shift Starts.
A spraymec holding a heading because bolting isn't complete. A jumbo waiting on a bogger. Two trucks queuing for the same loader. These interactions do not appear in your planning software because rate-based tools calculate from averages, not from how equipment actually behaves underground.
idoba.sim models each piece of equipment as an independent agent. The conflicts surface in the simulation, not on the shift report. With idoba.sim surface where the constraints are, adjust the schedule, re-run the scenario and go to sign-off with a weekly schedule you can defend.
WHY IS IDOBA.SIM DIFFERENT.
Agent-based Modelling. Not Fixed-rate Averages.
Conventional planning tools use fixed rates. idoba.sim runs differently. Every truck, loader, and jumbo operates as an independent agent with its own logic, constraints, and priorities. Loaders wait when the face isn't ready. Trucks queue when the decline is congested. Shift change effects ripple through the network the way they do underground.
Run 25 statistically varied simulations per scenario. The output is a P10/P50/P90 distribution, the realistic range of what your schedule can deliver. Not an average. A range you can work with.
Simulation Software Built for Underground Mining.
Cloud-based. No Complicated Infrastructure to Manage.
idoba.sim is cloud-delivered. Your team accesses it through a browser. No servers to provision, no software to install or maintain.
idoba.sim is built and backed by Perenti, with over 35 years of operational hard rock mining experience across Australian and global operations. The model reflects how underground mines behave, because it was built by people who ran them.
Built for Mine Planners and Schedulers.
If you can describe your fleet, your haulage network, and your weekly schedule, you can run a scenario. No simulation experience is required.
From Question to Answer in Hours, Not a Planning Cycle.
When your planning team uses idoba.sim the turnaround from question to answer is hours, not weeks waiting on an external engagement.
Ready to Stress-test Your Schedule Before It Goes Underground?
idoba.sim is built for underground mining teams who need to validate schedules before crews are committed, identify bottlenecks before they cost advance metres, and make fleet and sequencing decisions based on simulated results, rather than fixed averages.
-
Most planners use rate-based scheduling tools. These calculate a single expected outcome from fixed rates. What they cannot see is how trucks, loaders, and jumbos actually interact underground.
idoba.sim runs your weekly schedule through 25 statistically varied simulations and returns a P10/P50/P90 distribution. You see where the schedule is at risk before crews are committed, not after.
-
Improve advance rates by testing the full cycle before you commit to it — mucking, scaling, bolting, charging, re-entry. idoba.sim models the full development cycle as agent interactions across 14 shifts. Surface the conflicts, justify the extra jumbo, and resequence the headings before metres are lost.
-
Most Planning teams rate-based scheduling tools. These tell you where bottlenecks have been, not where they will be in the schedule you're about to commit to.
Operational simulation like idoba.sim uses agent-based modelling that replicates how loaders, trucks, jumbos and spraymecs interact across the mine network. It runs 25 statistically varied simulations per scenario and surfaces where the schedule is likely to break under realistic variability, using a probabilistic range.
