The Story Today
Todays Mining Landscape• High demand on local coal
• Focus on increasing production
• Land access issues
• Resources remain static
• Mining methods constant
• An interest in innovation
Why Is It Challenging?
• Resources are getting deeper
• Resources are complex
• Demand is increasing
• Planning considered difficult
Urgent Planning Issues
Common urgent issues include:
• Smaller properties
• Overlying constraints
• Open cast and underground mines in same vertical plane
• Geological disturbances
• Land and rehabilitation
• Skilled manpower
Why is Good Planning Currently a Challenge?• Complexities such as
• Multiple seams• Fire• Water• Gas
• Surface constraints
• Old mine workings
• Planning is often done while mining progresses
• Mines may not be optimised
• Geological and geotechnical data is complex and sometimes inaccurate
Technology?
• Software available, but often not used
• Medium and short term schedules not created to optimise the operation
• Testing of how the operation works prior to production not possible
• Software must be easy to use

Option 1Results of the long term plan:Y20:• 4,268,825t • 4,630m• 921.99 t/m
Based on tonnes per metre, this seems the better result

Option 2Y20:• 5,578,814t• 11,549m• 483.06 t/m
However, considering all constraints this option is:• Safer• Has better product quality• Geotechnically achievable• Less likely to have gas issues

Simulation
Common Modelling Issues
Equipment / fleet• Productivity improvements• Cycle times• Justification of new equipment• Delays
Mining constraints• Congestion• Changing variables • Changed mine design
Discrete Event Simulation• With the dynamic nature of mining,
simulation is required
• True – “discrete event simulation” requires a link to both planning and execution:• Evaluate plans and enable scenarios and
capital configuration to be tested prior to production
• Real time data from the operation feeds assumptions in the simulation model.
• The simulation model is always ‘learning’ from actual production data
• These learnings are then feed back into the plans – ongoing better planning
Plans will continuously be more accurate and achievable.
Targets are more likely to be met.
What simulation is possible?HAULSIM is a powerful tool to model, analyse, visualise and optimise your haulage network• Accurately model mine haulage• Visualise impact of changes• Quantify design improvements• Validate assumptions• Make informed decisions
TALPAC is a simulation tool for evaluating the efficiency, productivity and economics of the mine• work out the size of fleet• which equipment is the most compatible• investigate and compare time-period
productivity
New Mine Layout
Problem We are regularly not meeting production goals. Will changing the longwall design help to increase production? Questions• Will the change help improve production?• How will the change impact the surface
fleet?• Will the capacity of my conveyor network
keep up with the production change?• Will there be bottlenecks?
The answers to these questions can now be easily found and communicated and the right decisions made by doing a simulation
A 3D simulation solution for analysis of entire mining systems so users can accurately determine and test key system measurers.
• Improve equipment system efficiency
• Accurately test safety and/or production gain initiatives
• Quickly build simulation models and run scenarios
• Determine whether capital expenditure is required
• Dynamic dashboard reporting for instantaneous results
• Integration with RPM applications to simulate an entire mine plan including higher level costings
Summary
RPM’s XPAC Solutions

• Models updated automatically as the mine evolves
• The best, most sophisticated tool set to build your model, making it fast and easy to get results
Solutions have taken away the “good model” vs “bad model” problem.
Now, they are all good.
HAULSIM value
• Visualise ‘what if’ scenarios• Test haulage options prior to production• Explore multiple scenarios• Visualise the impact of changes in
minutes
Incorporating HAULSIM into your software suite will help you to:
• Justify new equipment expenditure• Reduce 3rd party consulting expense• Use past data to improve future
production• Operate more efficiently• Maximise production
Can you imagine?
Now that you know about coal solutions, and also the value of simulation. Imagine if you could combine the two?!
• Share parameters from the schedule into the simulation
• Make a change in the schedule, and immediately test the impact it will have
• Determine if your schedules are realistic
• Understand how likely your targets are to be achieved
