Open Cut Coal Solutions is a strategic scheduling solution developed specifically for open-cut coal mines. OCCS handles data and processes schedules faster due to unique parametric design and scheduling capability. It is 100% script-free and made up of pre-defined logic to generate schedules easily and more often.

When combined with the knowledge of mining engineers, it automatically determines what is practically possible to achieve across one or many mining operations. This agility gives engineers the ability to respond rapidly to the market, maximise output, and generate multiple scenarios to assess the best option. OCCS is a process-driven solution and easy to learn without coding experience and complex scripting.


Process-driven UI

Unique, process-driven UI. Learn in a few days, implement in a few weeks.

Automated reserving

Automatically creates the scheduling reserves from geology and design, whilst handling massive models.

Integrated destination scheduler

Simultaneously schedules mining and dumping, so you know the source and destination of every step.

Integrated haulage modelling

Detailed haulage modelling of every movement in the mine with automatic reporting of equipment requirements.

Intuitive, practical scheduling rules

Intuitive, sophisticated mining rules ensure schedules are always feasible and practical.

Dynamic scheduling

Dynamic scheduling allows a mix of manual and automatic techniques in the same schedule.

Scheduling speed

Incredibly fast scheduling speed – easy to study different scenarios.

Product optimiser

Integrated Product Optimiser finds the best way to process, blend and stockpile products to maximise value.

Enterprise integration

Directly integrated with other RPM Solutions and ERPs.

Redefining mine planning and scheduling

Underpinning Open Cut Coal Solution (OCCS) is a powerful scheduling engine that does all the heavy lifting without compromising sophistication and capabilities. From an individual site through to multi-site and global operations, the parametric approach adopted by OCCS means Engineers can amplify their decision-making process.

This embedded intelligence, together with our intuitive user interface, increases mine productivity and provides rapid ROI with a solution that is scalable, intuitive and fast to learn. OCCS is the only Enterprise Planning solution that complies with industry standards and aligns to ISA-95, delivering true collaboration across the mining value chain.

Mining rules

OCCS is specifically built for coal strip mines and engineers to produce accurate 3D stratigraphic block models of in-situ reserves from validated structures and grids. The rules-based coal seam aggregation converts the in-situ model into working sections, considering losses, dilution, previous underground mining and other seam modifications.

Integrated and dynamic haulage

A huge challenge with open-cut coal mines is the constantly changing haulage routes. OCCS allows users to plan haulage during scheduling with confidence. It cleverly considers the various haul routes at each schedule stage then provides the optimal route to move product from source to destination.

Product optimiser

Running simultaneously as the schedule progresses, Product Optimiser removes the need for pre-schedule or post-schedule blending strategies. Coal blending is also quite unique with the use of coal wash plants. There are specific inbuilt features with the coal solution which allows users to set either quality targets through varying wash densities or setting fixed wash density to achieve the desired product.

The Product Optimiser helps planners understand the mine’s blending strategy using linear programming on the availability of coal. The solution then blends to the most suitable product based on set targets and objectives whilst honouring blend restrictions.

Automate tedious processes

OCCS has inbuilt automated rules making it practical to do rigorous, long term schedules without spending months building the rules. The solutions still generate plenty of detail for budgets and short term schedules. For the user, Engineers can quickly test many planning models and assumptions and refine the ones that will deliver to the corporate objectives without spending weeks and months inputting tedious data.
