GEOVIA Minex FAQ

What makes Minex better than software not specialised for coal and other stratified deposits?

Minex has been designed specifically to support the needs of layered deposits.

What is the benefit of having an integrated end-to-end geology and mine planning solution?

Minex spans exploration, design, optimisation, scheduling, and rehabilitation. As a common single platform, data does not have to be exchanged with third-party systems, avoiding the data loss or corruption risks associated with import and export.

Why are gridded seam models more advantageous than block models?

When working with layered deposits gridded seam models allow for more accurate resource evaluations. The use of a gridded modelling system is more appropriate for stratified, layered, data intense and large scale geological deposits such as coal, bauxite, phosphate, some iron ore and lateritic deposits as it provides unique tools such as seam and fault modelling functions to help better interpret and model these types of deposits. Using a gridded seam model system you are more realistically able to visually depict the deposit characteristics than other systems such as “block modelling.” Ultimately, a more accurate model allows for better mine planning downstream.

How is a gridded seam model different from a block model?

In a block model you are estimating the volumes and percentage of ore and waste in a block whilst in the Minex gridded seam model, you are able to ascertain the exact position of the waste-ore interface, which is critical for short and medium-term mine design and planning. Minex offers a better visual representation of the stratified deposit by utilising gridded surfaces instead of blocks.

Does Minex support underground mines?

Yes. Minex provides users with the tools to create 3-D designs of mine layouts and reserves and to generate reports on all aspects of the designs and reserves.

Does Minex provide its users flexibility?

Yes. Minex gives users more control over the processes of mine planning as it is designed to operate as a tool to help geologists and mine planners perform their tasks more efficiently without removing the ability for mining professionals to be able to make decisions and interpretations based on their own experience and skills. Minex is a menu driven Windows-based user interface but also allows the user to compile more complex configurations and processes if required.

Is Minex easy to use and learn?

Yes. Minex’s Windows-based interface allows users to quickly adapt to the software as it is a familiar environment. GEOVIA provides either classroom or customised training which allows the user to get up to speed very quickly. Within a relatively short period of time software users are able to produce valid geologic models and produce practical mine plans and mine schedules.

What type of user support is available to Minex users?

GEOVIA provides global support for all customers who subscribe to the Update Service and Technical Support (USTS) membership, providing users with the option of either email or phone support, as well as knowledgebase online support through the GEOVIA Support website. GEOVIA also has a team of dedicated and experienced software and mining professionals that can assist companies with project work if required.

What is Minex’s Pit Optimisation module and how does it benefit a mining company?

The Minex Pit Optimisation module is a comprehensive software tool which can be used throughout a deposit’s life to continually reassess risk and guide mine progression in an ever-changing economic environment. By utilising the Lerch Grossman algorithm, the Pit Optimisation module can facilitate the creation of short, medium, and long-term optimal mining strategies within a very short turnaround.

By examining results of various scenarios based on fluctuating coal price, mining costs and design constraints, the Pit Optimisation module ensures that the size of economically mineable reserves can be accurately determined.

Using the module, mine planners can understand how to develop a plan to Maximise NPV and ROI by finding only the material which is “worth mining”. They can also see where to start a new pit, or where to mine next (the optimal pit progression) and determine the potential duration of a mine’s life and its expected profitability.

What is the advantage of the Minex Open Pit Scheduling module?

The Minex Open Pit Scheduling module employs an “interactive” methodology that allows users to graphically interact with the schedule as the schedule progresses. The module is simple and easy to use and allows users to make key scheduling decisions without the “black box” effect of other less interactive software offerings. It is integrated directly with the geological model and reserves database, creating more accurate and realistic scenarios.

Decisions such as those related to equipment movements can be made “live”, or as the schedule progresses through each scheduling period. You can playback animations of the schedules you have created to help spot bottlenecks, equipment downtime or opportunities to better utilise equipment.
