Vulcan 11 release targets efficiency

Maptek Vulcan 11 continues the trend of providing an increased number of automated functions and workflows. High impact visualisation, faster processing and better ways to work with large, complex datasets help users work even more efficiently.

In March we highlighted the tools coming for resource geology applications – data analyser and kriging neighbourhood analysis. This issue focuses on new options for engineers and mine planners, as well as performance improvements across a range of processes.

Maptek Workbench

The Maptek Workbench provides a unified platform for running Maptek applications. An updated search feature allows users to search for a specific term and run the function from the relevant panels returned in the search.

The Workflow Editor allows users to build a command list for automating routine tasks, incorporating Vulcan menu items as well as common desktop tools.

Users can choose between list or diagram view, dragging and dropping nodes that represent each process. Configured components can be saved to build new workflows. Pauses and triggers for processes can be built in.

Text, scripting and spreadsheet editing applications can be incorporated. Variables can be queried and users can troubleshoot workflows.

Visualisation

Graphics

Three new icons on the Graphics toolbar – Solid Slice, Quick Section, Tile and Tie – target niche tasks with big impact.

Users can easily generate slices from closed solids for a better view of data. Slices retain the colour of the parent triangulation, and transparency is optional. A slice can be created in either or both front and back ends of the section, or as a single slice in the middle.

The new Quick Section two-click operation requires input of two points to define a plane for slicing. Tile and Tie allows users to view multiple windows simultaneously; moving data in one window shows the data from the same reference point in each window.

Grade Control

New Grade Control features include dramatically increased speed for resolving samples, additional date formats and the ability to use Perl and Python scripts for grade estimation.

Plotting output has been improved, bench plans can be saved, blast reporting panels re-sized and grade blocks edited by a drop-down pick list.

Grade Control Optimiser

Continually improved since release in 2017, the standalone Grade Control Optimiser module helps operations improve the value of deposits. The latest update includes improvements to the core optimisation engine which guarantees locally optimal results.

The tool also includes an option to apply different mining widths. Users can choose to populate the classification grid by reading the variables directly from the block model.

The mineable optimisation area can be specified via an additional block selection, and the known upper bound is reported by the optimiser.

The time limit for the optimiser now applies to the entire problem, while recognising that the problem is split into multiple pieces.

Pre-scheduling

Vulcan offers different approaches when generating mining blocks for scheduling. Mining Block Generation and Pit Splitter enhancements provide greater efficiency and improved mine planning−scheduling connectivity.

Mining Block Generation employs a simple, repeatable approach, which also maintains flexibility for updates when running calculations. Any accumulation variable, such as insitu metals or volume, can be selected and applied as a target. Dynamic adjustment of blocks allows simple, interactive solid and attribute modification on the fly.

Another improvement in the mine planning−scheduling interface allows users to populate Vulcan block models with the results from Maptek Evolution optimisation. This enables creation of end-of-period maps and animation of the scheduling phases.

Pit Splitter provides a workflow-based approach to creating solids for strip mines, with reliable output applicable to all Maptek mine planning and scheduling workflows. In addition to exerting greater control over how pits are split, users can stipulate colours and devise formula-created attributes from generated attributes. Improved options support amalgamated projection methods, projection on grids, stacking and splitting in any sequence.
