How to Use Gemcom Minex Tutorial 3 for Coal Mine Planning
Gemcom Minex is a software solution for geology and mine planning of coal and other stratified deposits. It helps you to evaluate resources accurately and mine efficiently from exploration to rehabilitation. In this article, we will show you how to use Gemcom Minex Tutorial 3, which is a data set that comes with the software installation, to learn the basic concepts and features of Minex.
Gemcom Minex Tutorial 3 covers the following topics:
- How to create and manage projects and databases in Minex
- How to import, validate and display borehole data (lithology, quality, geophysics)
- How to correlate seams and create a stratigraphic model
- How to create grids and triangles from borehole data
- How to design an underground mine layout and calculate reserves
- How to design a surface mine layout and schedule the production
- How to use the 3D graphics environment and CAD tools
- How to create plots and reports
To use Gemcom Minex Tutorial 3, you need to have Minex software installed on your computer. You can download a free trial version from www.3ds.com/products-services/geovia/products/minex/. You also need to copy the tutorial data set from the installation folder (usually C:\Program Files\GEOVIA\Minex\Tutorials) to a working folder on your computer.
To start the tutorial, open Minex software and create a new project. Then, select File > Open Database and browse to the tutorial data set folder. You will see several databases with different extensions (.gdb, .mdb, .sdb, etc.). Each database contains different types of data for the tutorial. For example, the .gdb database contains borehole data, the .sdb database contains seam data, and the .mdb database contains mine design data.
You can open multiple databases at the same time and switch between them using the Database Manager window. To display data from a database, you need to use the Data Explorer window. Here you can see the different tables and fields that store the data. You can also edit, filter, sort and query the data using various tools.
To display borehole data on a plan or section view, you need to use the Borehole Plotter window. Here you can select which boreholes, fields and symbols to plot. You can also adjust the scale, orientation and annotation of the plot. To display seam data on a cross-section or fence diagram, you need to use the Seam Plotter window. Here you can select which seams, boreholes and attributes to plot. You can also adjust the scale, orientation and annotation of the plot.
To create a stratigraphic model from borehole data, you need to use the Seam Correlation window. Here you can correlate seams across boreholes using various methods (manual, automatic, geophysical, etc.). You can also edit, split and merge seams using various tools. The stratigraphic model is stored in a .sdb database as a series of layers.
To create grids and triangles from borehole data or seam data, you need to use the Surface Modeling window. Here you can select which fields or attributes to interpolate using various methods (kriging, inverse distance, etc.). You can also edit, smooth and filter grids and triangles using various tools. The grids and triangles are stored in a .gdb database as surfaces.
To design an underground mine layout from seam data or grids, you need to use the Underground Mine Design window. Here you can create panels, pillars, roadways and other features using various tools. You can also calculate reserves, tonnages and qualities using various methods (polygonal, block model, etc.). The underground mine layout is stored in a .mdb database as features.
To design a surface mine layout from grids or triangles, you need to use the Surface Mine Design window. Here you can create pits, benches, ramps and other features using various tools. You can also calculate reserves,
