The net result is high-grade, or “surgical” mining in which the quarry is designed to maximize profitability rather than simply mining the entire lease and relying on the sorting/milling process to separate the ore and the non-ore.Ī healthy level of skepticism must be employed when using computer software to compute resource volumetrics. These models are then filtered and combined into a final model that shows where all of the parameters (models) meet a set of user-defined criteria. For example, a clay deposit may involve the creation of separate models representing shrinkage, brightness, and slip. Values are estimated for these voxels based on their proximity relative to downhole data.

The foundation of these analyses involve the creation of imaginary block models in which a site is subdivided into a series of three-dimensional cells called a voxel (volumetric element). The next steps can involve the calculation of volumetrics and optimal pit-designs for example, in mining, based on a series of user-defined parameters. Once the database has been created, visualizations such as cross-sections, fence diagrams, and block diagrams are generated to check the validity and geological reasonability of the modeling. The basic strategy involves the creation of a borehole database that includes analytical results for various physical and chemical properties as a function of depth. plan based on the end-user specifications. Computer modeling in RockWorks provides a means for tailoring a mine, environmental, petroleum, etc.
