What’s New in Leapfrog Edge 2021.1
MULTIPLE DRILLING DATASETS
The most major improvement to Leapfrog data management is here. You can now have multiple drillhole data sets in your project. You are no longer limited by needing to import all your drilling data into a single drillhole object.
Now you can:
• Visualise new drilling in relation to an existing model before appending and triggering changes.
• Connect, display and model with data from different sources.
This functionality enables many new enhancements to workflows including:
• Modelling tools that allow addition of ‘contact points’ from drilling tables (deposit, erosion and intrusion surfaces) can now draw contact points from other drillhole sets.
• Vein segments need to be derived from the same drillhole set / interval table, however contact points from other drillhole sets can be added into vein surfaces using derived (linked) contact points from the points folder.
• Numeric interpolants can make use of values from a second drillhole set, by incorporating these via the points object/derived interval mid-points.
• Drillhole correlations can be made between data from different drillhole data sets
• Add data from different drillhole sets into section layouts.
In future we plan to extend the functionality of multiple drilling sets by allowing the creation of ‘merged drillholes sets’. This creates new ways to incorporate data from multiple drillhole data sets into models.
REMAPPING DATA TABLES
It is now possible to change the data source for existing drilling data, points tables and structural data tables, and remap these to a new source. Data can be remapped from any source to:
• local CSV file,
• to CSV files located in Central Datastore, or
• to an ODBC data source.
Remapping files to Central Datastore paves the way for dynamic linking of projects to database outputs. Projects using a Central Datastore source can leverage the file versioning and ‘out-of-date’ notification functionality of Central, to ensure timely updating.
DELETING HIDDEN COLUMNS
Delivering more flexibility in the project tree with the option to delete ‘hidden’ columns such as text.
CALCULATIONS AVAILABLE ON DOWNHOLE POINTS TABLES
Work effectively with calculations now added to downhole points tables. Calculations can be performed, or categories defined on data such as LAS measurements from geophysical tools, or CPT data from ground investigations.
FILTER EXPORTED INTERVAL TABLE DATA
When exporting data from interval tables and points tables, it is now possible to filter the export using any of the filters defined for that table or for the parent collar table. Meaning only final filtered values used in model construction can be exported for archiving or further analysis, without the necessity to reproduce complex filters in Excel.
SUB-SET OF CODES RESIDUAL HANDLING
A residual length and handling method can be specified for each separate code, allowing the effective use of variable composite lengths for different code sets.
MULTIPLE DEVIATION DRILLHOLE PLANNER
Introducing a new tool to deliver more flexibility to the complex natural deviation or directed deviation of drill holes. Easily export as a set of interval tables, as a polyline, set of points, or as a drilling plan.
• Natural deviation combines ground conditions and drilling practice. Cater to varying rates of build and turn when drilling through different lithologies or downhole configurations.
• Directed deviation is deliberately induced with directional drilling methods and input with length, TFA (tool-face angle) and DLS (dog-leg severity).
You can still design a navi-drive hole section with the natural deviation inputs of build and turn instead. To start a hole simply select a collar position (click on a surface and refine as required) and commence adding sections.
IMPORT OF TIME DEPENDENT POINT DATA
This new feature is available on the points folder and can be used to import and visualise any temporally stamped point data, such as micro-seismicity data.
NEW SUB-BLOCKED MODEL FORMAT
Optimise efficiency with major reductions in processing times.
• A NEW sub-block model format (based on octree branching) for geometry representation.
• Up to 6 levels of sub-celling (to 1/64th of the parent cell) supported.
• Cells (and sub-cells) are only triggered if a boundary passes through them.
• Models can be rotated on 2 axes.
• Up to 75% reduction of sub-cells when compared to our existing sub-block model.
• Results in significantly smaller projects and file sizes when models are exported.
• Up to 65% reduction in processing time in sub-block count.
Optimising the size and performance of octree models is ongoing.
Sub-block model import
More eagerly-awaited developments ahead…
• Import an octree sub-block model in CSV format into Leapfrog to visualise, validate and report.
• Add new triggering and evaluations while preserving the integrity of imported categories and values.
• The minimum sub-block dimension must be a binary sub-division of the parent cell dimension (in X, Y and Z).
• Arbitrary sub-block dimensions follow this rule, with arbitrary models already defined by this geometric constraint.
• To import, select columns and define the grid: parent and sub-block sizes, to position and extent.
• If the model is rotated there is currently two pre-set options for specific file exports from Leapfrog and Surpac.
• Models with two axes of rotations are supported.
We envisage the new sub-block model to supersede the existing format (except for applications where variable height blocks are used).
You can use the NEW Grouped Mesh tool in the Combined Models folder to:
• Group mesh together for improved evaluation (outside of a geological model).
• Evaluate directly onto block models, points, and flow models.
• Allow (most) closed volume meshes in evaluations.
• Arrange in order of sequential evaluation (highest priority at the top).
• Freely edit the name, category colour legend, or set optional custom background (after default).
• Define if evaluation applies category value inside or outside mesh volume.
Quick and easy evaluation of mining volumes (e.g, stopes, drives, blast boundaries, ore blocks) onto block models for grade/tonnage reporting without building a geological model first.
Previously, the only way to check if an object had downstream dependencies was to ‘fake delete’ it - then hit cancel. A risky move! Now it’s possible to safely view the inputs/outputs of any object in the project tree, with arrows and hotkeys to quickly drill down to the details.
Updates to the Confirm Delete dialogue now has links to:
• A full list of objects to be deleted and reprocessed.
• The View Relationships window.
ESTIMATION PARAMETER TABLE IMPROVEMENTS
A NEW Folder filter in the Estimation Parameters Report window.
Organise the project tree by subfolders, select inputs into the parameters table (e.g., estimations into domains, or another logical grouping) and review either individually or collectively. The estimation parameters table content is updated live as changes are made. Elements displayed in:
• RED highlight missing settings or details requiring attention (such as a spatial model deleted that an estimator relied upon).
• GREY indicate a field requiring a running processing update.
• BLACK denotes the value is up-to-date and not in error.
In the future, we intend to allow editing through the table view.
