The block model consists of interpolated values instead of true measurements.
There are other ways to achieve a result.īlock modelling concepts The block model is a form of spatially-referenced database that provides a means for modelling a 3D body from point and interval data, such as drillhole sample data. Note: This workflow demonstrates the steps in this tutorial. Requirements Before you begin this tutorial, you must have: lĪ good understanding of the basic Surpac concepts of strings, segments, DTMs, and string tools Surpac installed on your computer the data set accompanying this tutorial Introduction Overview By working through the examples in this tutorial you will learn: l l l l lĪbout Surpac’s block modelling module and the concept of block modelling to fill a block model from drillhole data from a geological database to constrain a block model to filter out specific blocks to report volume, tonnage and grade from a block model about column processing of a block model
