Computing Aggregate Reserves for a Site with Two Isolated Carbonate Units Using RockWorks

The purpose of this study is to compute the total economic reserves for a site that includes two carbonate units; an upper limestone and a lower dolomite separated by a shale unit. Quality analyses have been obtained at one-foot intervals within the carbonates. The following diagram depicts a typical log showing the lithology, stratigraphy, and aggregate quality.

Using RockWorks for Dredge Mining

Create a RockWorks Borehole Manager Database containing Bore Location information and %Sand Assay data. This data can be entered into the Borehole Manager by hand, or can be imported via Excel or an ASCII file.

Modeling a Multi-Seam Coal Reserve using RockWorks

This Case Study documents the modeling and visualization of a Multi-Seam Coal Reserve.
The coal layers and surrounding sediments have been broken up into eleven different stratigraphic layers. The top OB unit is Overburden material above the first Coal layer, C1. Units C1 through C5 are coal layers. Units I1 through I5 are interbed units.

Volumetric Analysis & Three-Dimensional Visualization of Industrial Mineral Deposits

Base and precious metal deposits are typically characterized by a single parameter such as the total weight of mineable gold. Industrial mineral deposits, on the other hand, are characterized by their end-use. For example, the volumetric evaluation of a limestone deposit depends upon who’s buying the product. The concrete industry has a suite of evaluation parameters such as silica content and abrasion coefficients.
