CoalLog formats in GEOVIA Minex 6.5 explained

By

Geologists in Australia can now import all 213 “CoalLog – the Australian Logging Standard” lithology symbols in .dxf format for both faster reporting and compliance with government regulations. This means that GEOVIA Minex meets the Australian Coal Logging legal reporting standard (CoalLog v2.0), which captures, shares and reports coal exploration data in a consistent format.

The CoalLog standard establishes a consistent format for coal data, data code translation tables and other transferral conventions. It was developed by representatives from major Australian coal mining companies, consultants and software companies, and regularly reviewed by companies, such as Dassault Systèmes to ensure it remains up to date.

The new lithology symbols in Minex contain ROCKTYPE symbols that are used to fill borehole plot traces such as profile plots and cross sections. Hatch patterns can also be imported to Minex symbol files, and users can now import coal log graphic patterns in .dwg or .dxf format into Minex, as per the below image.
