Introducing Datamine Studio 3

A man is to suffice his salary rather than salary to suffice the man.

Geological Modeling in Datamine Studio 3

Preface.

I had read the course to several groups of mining engineers and geologists at various mine sites in Kazakhstan. First wrote in Russian, this course is just an attempt to translate spirit of Datamine® tutorial -- excellent and overwhelming, and was written in parallel with teaching at classes, later on having been corrected and updated interactively in real time mode based on the students' questions and wishes.

Datamine file categories

In project session, Datamine files are variably devided into 2 categories: internal and external. If a file is added to a project, it is considered internal. Certain manipulations in Studio 3 require files to be added into the project before performing calculations or operations. Any datamine file, which is not added into the project is considered external. Technically there is no difference between the files. One and the same file may be external for one project and internal for the other.

Datamine file types.

In this tutorial we will use the following types of Datamine files:

  1. Points, *pt.dm
  2. Strings, *st.dm
  3. Wireframes, *tr.dm
  4. Block model files -- restricted space, filled with virtual parallelepipeds with predifined dimensions, representing geological phenomenon populated with assay, litholgy and other engineering attributes. Block model files also have *.dm extension.

Importing external file into Design window

In Studio 3 the term external file is rerserved for Datamine files. From Studio 3 point of view, CAD or TXT file being imported, manipulated, or exported, can not be considered internal or external. If you have not yet downloaded sample files, go to sample files section to download them, or else download a single sample file, a wireframe of a tectonic faults, used in this exercise. Un-RAR it within the directory it is saved on you hard disk (should be C:\\Downloads) To import it into Design window as an external file, go to Instrument panel, Data | Load | External Datamine File | Wireframes

Design Window
Load External Datamine File

Browse for the file tm_quartz_fault_wfTR.dm on you hard disk, select it and press Open.

Design Window
Load External Datamine File

In the next window select tm_quartz_fault_wfPT.dm and press Open

Design Window
Load External Datamine File

Press OK

Design Window
Load External Datamine File

Press OK in the next window. A wireframe file of a tectonic fault will appear in Design window

Design Window

IMPORTANT NOTICE

Broken Arrow
Once you have Studio 3 installed on your machine, you would already have Datamine official training files available on your hard disk before you start the program first time. However in this training course I will be using files I had made while working on a TUXMANNEWK project near Broken Arrow, CUSIANA, CASANARE, COLOMBIA. Warning

Visualizer

While in Design window, type uv, the abbreviation for Update Visualizer, to activate Visualizer window. Rightclick on the Visualizer window and pick up the options to change view angle, rotate, perspective, etc.

Visualizer Window
Tectonics wireframe, Visualizer window.

Press Design tab to return to Design Window. Depending on the coordinates of the view point, the file loaded in Design window may not fit into the screen area and not appear immediately. Or when you unload a file, it still might look present on the Design window, though absent in memory. In this case type rd to redraw the screen.

Regeneration of the screen is common procedure in CAD systems. Some of them, like AutoCAD, have, if engaged, a function of automatic regeneration of the screen to clean it up from the traces left by removed or unloaded objects. In Datamine Studio 3 you can use manual regeneration only.

You can change view angle interactively right in the Design window by holding Shift key and moving the pointer around with left button on (Shift+Left Button). Remember, you are not rotating the object. You are just moving the view point around.

To return to plan view, type 1 and click on the window anywhere within the empty area and select Plan from the menu. Press OK

Visualizer Window
Plane By One Point.

You can change the view plane in Design window by picking up options from the Set Viewplane menu after selecting View | Set Viewplane.

viewplane

Project directory structure

By default, Studio 3 creates Database folder on disk C:, C:\Database. As mentioned above, when creating a new project, the program also offers you to save it in a Project folder in Database folder. In a project folder it is recommended to create CAD folder for supported vector drawing formats (*.dwg, *.dxf, etc.) other than *.dm, and ODBC folder for Excel, Access, text and CSV files. Studio 3 session file *.dmproj and *.dm files are kept directly in the project folder.

Loading AutoCAD terrain isoline sample file

If you have not yet downloaded sample files, go to sample files section to download them, or else download RAR file either by clicking here or on the picture below. The file contains digitized isolines of a mine site terrain map. Un-RAR it into C:\Database\Project1\CAD .

directory
AutoCAD terrain.

Adding CAD file to the project

We will add previously downloaded AutoCAD file to the project. It is important to categorize the file based on the type of objects included in it -- poitns, strings, or wireframes. This time the objects are strings. It does not matter where the CAD file is located -- in CAD folder of your project, somewhere else on the hard disk, or on the memory card. By Adding To Project you create Datamine files out of CAD files -- In Design window go to Menu bar > File | Add To Project | Imported From Data Source.... In Import Data window, Driver Category pick CAD, pick AutoCAD(stings) in Data Type. Press OK

import CAD
AutoCAD import

In the Open Source File window locate and select the desired file an press Open

import CAD
AutoCAD import

In the Read drawing file tick off Load All Layers to view the AutaCAD layers you would want to use. This time we use all of them. Press OK

import CAD
AutoCAD import

Tick off Table file box and leave Point file and String file boxes intact. If you do not want to keep Autocad file name for your Datamine files, you should enter a new one in Base file name field. Press OK.

import CAD
AutoCAD import

Two new Datamine files are created in your project folder -- string file and point file. They share names with the same root, but different ending -- ST for strings file and PT for points file.

Adding Datamine file to the project

If you have not yet downloaded sample files, go to sample files section to download them, or else download a single sample file, compressed file of digitized isolines in *.dm format. Remember, Datamine creates 2 files of sting objects -- point and string file. Unpack the RAR file. Go to Instrument panel, File | Add to Project | Existing files...

Add DM
Adding Datamine file

Select _tuxmanook_topoST file and click Open.

Adding Datamine file

The file will be added to the Project. You can check its availability in the Project Files tab on the left of the Design window.

Data Export to AutoCAD

Very often you will need to export Datamine files you created in Studio 3 session into other CAD system to share your work with other individuals or groups which may not necessarily use Studio 3 in their work, such as surveyors, geotechnical or civil engineers, etc. The most popular file exchange format is DWG and DXF (drawing exchange format) by Autodesk. DXF can be imported in any CAD platform.

In design window, go to Data | Export
