Maptek Eureka


Maptek Eureka provides one integrated platform for viewing and analysing mining project data. Eureka 5 shares the Maptek Workbench environment with Vulcan, offering integrated workflows, data sharing and access to additional applications on a single platform.


The interactive 3D environment allows geologists to visualise and model exploration and project data including drilling, geophysics, seismic, GIS data, terrain maps and other imagery. When geophysical data such as seismic, gravity and magnetic surveys are viewed in the same space as exploration drilling data, intuitive correlations can be confirmed.

Spatially located data put into context promotes better understanding of the inter-connecting relationships between the disparate information. Viewing the data at different scales allows users to see the big picture as well as analyse local areas of interest.

Eureka’s CAD, geodesy, drillhole database and correlation tools and high impact visualisation are valuable aids for geological modelling. Smart CAD tools give unparalleled control over the working space within complex 3D datasets.

 

Enhancements to stratigraphic modelling functionality in Vulcan and Eureka are designed to ensure you spend less time processing data, creating opportunities to apply your expertise to critical analysis and decision making.


Users can customise settings for input drilling data, resulting in better validation and easily select modelling targets. Attributed data can be accessed from Maptek Vulcan or created in Eureka. Search, filter and highlight object tools provide for detailed analysis.

Drilling data stored in an Isis database is shared between Vulcan and Eureka. Any changes to the database made in either package are dynamically updated on screen in Eureka. Similarly, implicit or other types of models created in Eureka are readily available for use in Vulcan as triangulation files.

Tile and tie views allow linked viewing of Eureka data on one screen and the same or different data in Vulcan on another, while maintaining individual/dedicated file explorer and menus.

 

Accurately identify coal seam horizons using the MWD (Measurement-While-Drilling) and LAS drillhole functionality in Maptek Eureka and use I-Site Studio geological mapping tools to create an exact surface which enables precise drill & blast planning.

Implicit modelling

Eureka implicit modelling is an effortless way to create and edit orebody models for first pass volume calculations. Eureka uses a radial basis function approach to implicit modelling, accepting a wide range of input data types including triangulations, point sample data, and direct drillhole intercepts, as well as lines, polygons and ribbons.

Geologists can select all or part of multiple ISIS or CSV drillhole databases, CAD control and triangulation envelopes and quickly make an implicit orebody model. Use of interactively oriented ellipses allows the geologist to visually guide the output. Output models also contain a reference to all the data and parameters used in their creation. This offers both an in-built model audit as well as the ability to easily recreate variations of the model based off the same data and parameters.

Multiple orientation ellipses can be used simultaneously to control the models in structurally complex situations. This approach is well suited to elongate and variably sampled modelling, and Eureka offers an additional method tailored to modelling thin steeply dipping vein type deposits, whereby the hanging and footwall models are created as implicit surfaces.
