Carlson Geology

Advanced Geological Modeling for Confident Mine Planning

Carlson Geology is a comprehensive geological modeling solution designed to transform drilling and sampling data into accurate, reliable, and easy-to-use geologic models. By leveraging drillholes, channel samples, and user-defined 3D polyline data, the module enables geologists and engineers to build realistic stratigraphic grids and block models using industry-standard algorithms.

Built to operate directly within a CAD environment, Carlson Geology supports reproducible modeling workflows that adapt easily as new data becomes available. From exploration through reserve estimation and pit optimization, the software provides the tools needed to analyze geology with confidence and precision.

Drillhole Data Management

• Import drillhole data from virtually any format using custom settings
• Store drill data directly in the CAD drawing or dynamically link to external databases
• Draw geologic columns in section view or full 3D to correlate strata
• Validate drillholes using queries and detailed reports
• Build complex models using Strata Polylines, Horizon Codes, and Drillhole Equations
• Import E-Log geophysical LAS files and core imagery

Geological Modeling

• Use industry-standard modeling algorithms for accurate geological representation
• Create macros to quickly update models as new data is added
• Inspect models using colored and hatched isopachs
• Enhance stratigraphic detail with Limit Lines and Strata Polylines
• Automatically model seam splits and strata pinchouts
• Account for incomplete drilling using conformance settings
• Compare geologic and mining models to quantify available versus recoverable reserves

Cross-Sections and Fence Diagrams

• Plot geologic cross-sections or view them in real time with dynamic section adjustments
• Color sections by strata or grade and overlay drillhole data
• Stack sections in 2D or visualize them in 3D with topography and mine designs
• Generate accurate dragline range diagrams using true geologic models

Fault Modeling

• Add fault lines with variable dip angles and displacements
• Model normal and reverse faults in 3D
• Automatically calculate fault shifts based on surrounding drillholes
• Label strike and dip quickly for fault interpretation and mapping

Mine Reserves and Analysis

• Estimate reserves using weight-averaged quality attributes
• Generate strip ratio grids to identify economically viable mining areas
• Produce detailed reports using custom equations
• Export data to text, Excel, Access, XML, and other database formats
• Classify reserves as measured, indicated, inferred, or hypothetical
• Refine reserve estimates using waste dilution, recovery percentages, variable densities, and thickness filters
• Calculate pit reserves by vertical quantities, highwall slopes, or bench-by-bench designs
• Visualize volume changes over time using surface history files

Kriging and Variograms

• Generate block models using 3D Kriging, Discrete, and Inverse Distance algorithms
• Analyze spatial trends with the Variogram Generator
• Define nugget, sill, and range using full 3D anisotropy
• Select variogram types including semivariogram, covariogram, and correlogram

Block Viewing and Inspection

• Define grade ranges and attributes for reserve classification
• View partial or full block models with inclusion or exclusion constraints
• Isolate block grades to analyze specific material qualities
• Inspect models by depth or elevation with real-time grade feedback
• Overlay drillholes, surface topography, and mine designs for full context

Optimized Pit Design

• Define block values using user-defined equations
• Create value block models to assess profitability
• Generate optimal pit shells based on economic criteria
• Re-run scenarios as costs change to evaluate revised pit limits
