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.

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

IT IS TO BE REGRETTED THAT VISUALISER WINDOW IS OBSOLETE IN STUDIO RM.

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.

Users of STUDIO RM can still use the uv (Update Visualizer) key combination in Design Window to update current view in 3D 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

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.

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(strings) in Data Type. Press OK

The Bottom Line

Datamine Studio 3 is a typical Windows praphics program that makes use of menus, toolbatrs, panels and paletts. However, every program has its own peculiarities you have to remember. To make sure you mastered the procedures you learnt, it is recommended for you to follow the exercises at the end of each chapter.

  1. Create a new project.
  2. Organize project directory.
  3. Add AutoCAD file to the project.
  4. Add external Datamine file to the project.
  5. Load external Datamine file into Design Window.
  6. Load AutoCAD file into Design Window.
  7. Switch to Visualizer Window.
  8. Export AutoCAD file to Datamine file format.

Chapter 2. Drillhole Modeling.

What will be modelled.

Information about the ore body geometry has been obtained from the drillhole data analyses. The sketch below shows what we will be modeling.

sketch, ore body
Geological plan.

Vertical cross(NW) section.

Studio RM offers an advanced automated method of ore body wireframe construction, especially useful for narrow vein wireframe modelling. However it does not give straightforward results and need further adjustment, which requires betters skills. Therefore at this stage the tutorial will go through traditional string modeling, which is applicable for any kind of ore body geometry.

Excel Database Tutorial

View or download detailed instructions of creating Excel database for drill hole modelling. Though it is not mandatory to learn them for the moment.

Importing Excel Data Files

Excel drill hole database file tm_drilloles.xls will be used for creating Datamine drill hole file. You can click on the file name to download it if you did not do it before. As you can see on the picture below, there are 4 sheels in the file: Collars, Surveys, Assays, Zones.

sketch, ore body
Collars Sheet.

These 4 spreadsheets will be used for creating Datamine drillhole table files. For Collars file, Go to File | Add to Project | Create From Datasource

Import From Data Source

In the Data Import dialog box, select ODBC as the Driver Category and Tables in Data Type and press OK

Data Import ODBC

In the Select Data Source dialog box go to Machine Data Source, and select Excel Files and press OK

Select Data Source

If the Excel Machine Data Source does not work on you your machine, you will receive a Microsoft warning. With Studio 3, this happens on the minority of the machines and mainly is created by your MS Office configuration. Press New in the Select Data Source dialog and follow instruction of building a new Excel based data source. For more details, go to ODBC Driver Setup For Studio 3 / Studio RM section

Selecting Workbook

In the Select Workbook dialog navigate to the project directory and Excel file location and click tm_drillholes.xls in the Database Name list. Press OK.

Select Data Source

In the Table Selection dialog box make sure the System box is ticked on, then check 'Collars$' box and press OK

Table Selection

In the Tables dialog box leave all the boxes checked and press OK

Tables

In the Import Files dialog box Datamine creates default name (collars$) with a $ sign at the end as an indication of a supplementary table file to the drill hole creation process. You may change the name as you would need it if you have more than one collar file in the project, but always retain the dollar sign. At this stage leave everything intact, press OK

Import Files

Repeat the same steps for creating surveys$, assays$, and zones$ files, but checking corresponding boxes in the Table Selection dialog. In the end you will have 4 supplementary files for creating drill hole file using HOLES3D command.

Table Selection Assays

Wnen working on Assays data, make sure the meaningfull fields are checked on the Tables Dialog, and tick off the check boxes which might accasionally be highlihted by your system.

Creating Drillhole File

The process is called Desurveying of drillhole data tables (Collars, Surveys, Assays, Zones) to create 3d static drillholes. Use HOLES3D in the Command Line at the bottom of the User Interface: an entry box with white field preceeded with !>>> indicator . The letter case does not matter, you can enter hoLes3D or HoleS3d with the same result, but if you come across with the command in capital letters in this manual or in the Datamine Product Help, it is a convention to type it into the Command Line. (Commands outside the Command Line in the Design Window are described in the lowercase). Type HOLES3D (remember not to pay attention to the letter case, upper case is just in the tutor to indicate you must type in the Command Line) and press Enter.

Command HOLES3D
!>>> Command Line

Use selection buttons to the right of the HOLES3D dialog to select corresponting drillhole tables in the Input Files section and type a drillhole file name in the Output Files section. You can type in a table file name in HOLESMRY and ERRORS fields and the program will save the info about the data summary and errors if present. The latter is especially useful for locating either data entry errors, or downhole survey errors and other mistakes in field logging. Press OK.

Design Window in Studio RM

Studio RM is a revolutionary step forward in the Studio series. Thought the developers did not include Design window into the start up configuration, but could not get rid of it because even the Product Help informs you that for some of the operations Design Window is mandatory. It is also easier and faster to work in Design window.

RM
Visualizer replaced by 3d window

I prefer working in Design Window. Luckily, the developers still allow you to return the Design view back on the UI. But you will have to do it on every new session.

Right-click (R-click) at any spot on the side bar, select Windows > Design.

You will be returned back to the Select Data Source dialog with the updated list of ODBC drivers. Select StudioRM database driver you've just created, and click here on Select Workbook. to follow correspoinding instructions.

Select Data Source RM

The rest of the procedures for creating drillhole table files (collars$, surveys$, assays$, zones$) are the same in Studio 3 and Studio RM with one important exception:

Unlike Studio3, Studio RM does not automatically save drillhole table files (*$.dm). These files are kept in the memory untill you turn off the session. Therefore, make sure you save them in your project folder before closing the program.

To save collars$.dm, go to Main Toolbar, Data | Export | External

Data Export

Select Collars$, press OK.

Data Export

Browse to your project directory and save it as collarsrm$.dm to distinguish the file from the one you created in Studio 3 session (if you use both programs). Press OK.

Data Export

Go back to Main Toolbar and create surveys$, assays$, and zones$ files and save them to the project. Refer to Desurveying Drill Holes section of this manual to create 3d drillholes in Studio RM with HOLES3D command.

Static Vs. Dynamic

Drillholes made with desurveying process are called Static. Another type of Datamine drillholes is Dynamic. You do static holes first, then dynamic holes out of static ones (if needed). But before I show you the procedure, you should understand the difference. To my opinion, the necessity of dynamic holes depends on the accuracy of downhole survey in the field.

Many experienced Datamine users, even those self-decorated with notorious AusIMM note at the bottom of every e-mail, may not know what is static hole and what is dynamic. I’ve met with the one in 2008. 10 years later he still did not know what I was talking about.

Dynamic drillholes inhabit only the Design Window current session. You can not find them in the Project File or in the Files Window. But you can rebuild static drillholes which inherit properties of dynamic drillholes.

Drillhole trace is not a straight line. Rather, it is a compound curve because drill bit penetrates layers with different physical characteristics, which coupled with drill rod rotation efforts make the drill bit diverge from the straight line. When a field surveyor makes a downhole survey of the drill bit penetration into the ground, he writes down sample intervals dip angle and dip direction. Studio 3/RM algorithm of HOLES3D command calculates location of midpoints and builds 3d drillholes and locates them on the imaginary drillhole curve. Since the sample interval is a straight line, placing the centre point on the curve of the trace automatically means end points are out. But how much should they be out? If the downhole survey is both accurate and precize, you do not need to worry about it as much as the gap between sample ends is not noticeable. But downhole survey equipment and human errors in the field can do a significant impact on the issue making the drilhole samples look like the ones I draw or even worse! Probably this is the point of Datamine dynamic holes process when static holes are re-surveyed to make sample end points meet to the detriment of the sample centre points having been distanced from the hole trace. Both types of drillholes can be used for ore body modelling and estimation. Probably, dynamic holes have some reserved functions for development in future.

statics Vs. dynamic

Opposite to dynamic, static drillhole centre points lay on the drillhole trace. Correspondingly, sample interval end points are out of the trace line.

Creating Dynamic Drillholes

You will need table files you created for HOLE3D process downloaded into the session. Go to Project Files, select files by pressing and holding CTRL button and clicking on the *.$ table files. Then release CTRL, R-click and choose Load.

When do you need to use dynamic hole manipulations?

I've come across with a lot of examples, when dynamic hole process is the only remedy. This happens if you import drillholes made in Micromine. Micromine is 2.5D software while Datamine is true 3D! As usual, you do not have access to the raw database to make drillholes from scratch because those who gave you a crumpled Micromine file will make sure you do not have the database available. Another issue might have been the downlole survey performed not accurately enough. In both cases use dynamic drillhole modelling.

Static Errors
Example of crumpled drillhole made in Micromine prior to importing into Datamine. Dambludi mine, Georgia.

Below is the picture of the same drillhole cured by the dynamic process. The effect is obvious, though not perfect. This is maximum you can do with fabricated Micromine drillhole file. If you have access to the drillhole database, you can be more specific: it might happened to be the downhole survey or/and records issue. If so, you have explanation to your HOLES3D drillhole geometry on the picture above, and the dynamic process effect on the static drillhole on the picture below. You are the only manager of your project and must be able to answer questions.

Type twsl which is an abbreviation for toggle wireframe slice, then type rd to redraw the screen.

Your screen view might be different. It depends on the view plane elevation, which can be controlled by Move Plane Forward and Move Plane Backwards buttons on the right sidebar.

Setting Up Vertical Section

Press the 2 key on the keyboard, target along the apparent continuation of any drill hole row, click and hold the mouse button on the screen to the left then drag the cursor to the right as if you want to slice along the row. A rubber line follows the cursor. Release the mouse button. In the Select View Orientation group select the Vertical Section radio button, press O'K

A vertical section is displayed. Though all the drillholes are apparent and pile up to create a mess. What we want is to turn off the drillholes that do not position on the vertical plane we created. This is done through the View Settings dialog box by pressing View Settings button on top of the side bar.

In the View Settings dialog box set Width: to 20, and tick on the Apply Clipping check box. Click O'K. 20 metres is the clipping width. It means that the objects (drillholes) or even patts of the object located within the width, will be the only visible on the screen. You should alway try different width values to adjust visibility of objects per your task requests

It seems the Turqouise colour we picked up for the sulfide area is not standing out enough against the light gray colour of the absent grades. Probably it would be better to change the colour in the palette. R-click on the view, Select Format Dispay...>Drillholes>Format... . In Drillhole Traces dialog menu press Color tab. Press Edit Legend button.

Creating Strings

Type ns on the keyboard for new string. A colour palette apears at the bottom of the view, from where you can select the colour for the string. Pick the red (#19) colour.

New String

Draw a sting as on the picture below. Use left button at the tectonic faults and right button for exat positioning of the sting point at the oxide zone top and pottom points. Remember, when string command active, right mouse button is used for exact snapping of the string points. If you use left mouse button, the point is placed on the view plane. Use Zoom In and Zoom Out buttons while drawing the string. The ns command remains active until you press Cancel button at the top right corner of the view port. Also, use right button to position the last point of the sting with the first one. Note, that the sting is indicated in yellow, which is the default colour for selected objects. Therefore, never use yellow colour for objects otherwise you will be misguided.

Warning!!! Use left button if you do not need exact positioning. Do not use right button click at the tectonic faults wireframes. I you do, your string point will randomly snap agaist the closest wireframe triangle ponit, which can be way out of your drawing plane.

Finally, you need to save the sting in a file. With the sting still selected, press Save Current Object button on the Main Toolbar.

Navigate to project folder and enter oxide_strings in the file name box. Press Save button.

Always keep an eye on the object type and active object name box in the Main toolbar. All the cross sectional strings of the oxide zone must be saved in one, oxide_strings.dm, file. If you create new strings by accident while working with oxide_strings.dm, all the newly drawn strings will belong to the new string object. Seemingly, if you have more than one string object file, accidentally it may become active so that stings you draw will be saved in the very current object, which could not necessarily be the one you want to update. Therefore, always pay attention to the current object.
