    TIPS

    If, at any time, the Minex Explorer indicates that the link to the project folder is broken, view the broken link

    property and open Windows Explorer to check whether the folder exists. The folder might have beenrenamed or moved.

    2. Click Toggle Black/White

    The background of the Graphics window will become white when you show some string data.

    In some situations, white provides a better contrast for the data; in other situations black is more suitable.

    3. Right-click MAP.GM3, and click Display.

    Structure Data TypeStructure data type is 3D line and point data used for storing strings and points representing topography or geological

    structural surfaces such as coal seam roof and floor, crests and toes, and surface spot heights.

    Mask DataMask Data is 3D string data used to represent closed polygons. These polygons are used to represent enclosed areas and are

    use for masking operations on triangles and grids.

    Base Map Data

    Minex5.2Minex5.2 ConceptsConcepts GridGrid

    A grid is a virtual surface that represents a geological interface:

    - Geological structure: seam floor, seam roof, seam thickness, topography, weathering zone

    - Geological quality: calorific value, ash, sulphur, moisture, volatile matter, fixed carbon

    The z attribute (elevation values in the example below) is stored at the centre of each square of the mesh.

    This centre point is often called the grid node, or centroid.

    All objects are removed from the Graphics window and all the files that were displayed are closed.

    By clicking Object Control Panel.

    The object is removed from the Graphics window but it remains open.

    Tip: Try changing the transparency of an object to 50 instead of turning its visibility off. This technique is useful for reducing the prominence of an objectwithout completely hiding it.

    Plotting Modes

    F This plotting function allows you to plot with basic line styles for fast plotting and design work.

    P This plotting function allows you to plot set-out lines i.e. those used to set out symbols and base

    map text etc. This function is also called Pen plot as it allows you to plot strings in the pen

    number defined in the layer field. This is useful for displaying groups of strings in unique colours.

    ECS Shows all true line styles with all the symbols. Lines are not simplified for faster plotting. Usually it

    is fine to use this plotting function these days with the advent of more powerful computers.

    When you are creating or editing a string, or making any other changes or additions to a geometry file, you

    must save the geometry data file to keep the changes.

    In addition, when there are unsaved changes Minex displays a disk icon on the geometry file in the Minex

    Explorer.

    To save a geometry file, right-click it and select Save Geometry File.

    When you try to exit Minex, and there are unsaved changes in the geometry file, Minexprompts you to save.

    1. Origin and ExtentDig the lower left and upper right corner

    2. RotationThe default rotation is 0 degrees with grid Y pointing to the North of the grid. Apply a rotation if required

    3. Mesh SizeTo accurately reflect the data, the rule of thumb is:Mesh size ideally should be 1/4 the data spacingor

    Mesh size should not be more than about 3 to 4 times of data spacing.

    4. Scan DistanceAn algorithm must be able to observe the raw data when generating a value at a given mesh point on the surface.The user gives a scan distance(s) to the algorithm. If raw data is found within the scan distance then the algorithm willproceed to generate a mesh value, the rule of thumb:

    Scan distance should be 3 times the maximum data spacing.5. Data Boundary

    1. MethodsLog Gridding: converts the input data into natural log form for gridding can be used to ensure no negative

    values are produced

    Extrapolation: Uses gradient information and honors the trend of the data recommended for topography

    2. AdvanceThere are three options you can choose: Regional Gamma, Interpolate Gamma, and Confidence.These advanced options allow you to smooth the grid during creation

    3. Grid ExpansionThe Fill option enables the model to expand beyond the data until the full model is created

    The Distance allows grid values to be extrapolated above or below real data values. This facility honors thetrend of the data and is recommended for structural grids such as topography.

    Some users require that the grid extend only to the data boundary. In geological applications, there may be validreasons to expand the grid surface beyond the data - eg beyond boreholes to the lease boundary

    4. Grid SmoothingAllows a filter pass to be made on the grid mesh to reduce small irregularities.

    With this option you can specify the radius of the area to be smoothed* a filter of 2 - 4 times mesh size is light or cosmetic

    * a filter of 9 times mesh size is MAXIMUM allowed by the system and this wouldbe regarded as a heavy or extreme filter.

    5. Limits

    '*' allows two input triangles to be multiplied.The output triangle has the X, Y parameters (origin, extent and mesh size) of the first input triangle.The elevation or Z value of the output triangle is the product of the two input triangles.

    '/ allows two input triangles to be divided.The output triangle has the X, Y parameters (origin, extent and mesh size) of the first input triangle.

    Set Null , If you choose the Set Null option, the value of all mesh points in the affected area will be converted

    to NULL.

    Set to Surface NumberIf you choose the Set to Surface Number option, the value of all mesh points in the affected area will have the

    specified surface number added to the grid value. Note that this number (0 - 9) replaces the least significant

    digit in the Z value at each mesh point.

    To be effective, each area of the triangle MUST be given a surface number, or else those areas not given one

    will have a random surface number.

    Set Constant

    If you choose the Set Constant option, the value of all mesh points in the affected area will have the specified

    constant replace the grid value.An example of using a constant is where a polygonal outline might represent the floor of a pit. The constant

    would be the elevation of the pit floor.

    Add Constant

    If you choose the Add Constant option, the value you specify is added to all mesh points in the affected area.

    Smooth - Curvature

    The value you specify in this field is the radius of the curvature you want to use to smooth the points in theaffected area.

    o Origin/Extent: Choose the Origin/Extent method if you want to type in Origin and Extent (distance) X

    and Y co-ordinates. The Dig button can also be used with this method.

    o Origin/Scale: Choose the Origin/Scale method if you just want to type in an Origin and the Scale touse. When you use this method, Minex will calculate the Upper and Extent values for you based on

    the scale you specify. The Dig button can also be used with this method.

    o Surface Extents: Choose the Grid Extents method if you have a "current" grid in memory. Minex will

    fill in the Origin and Extent values based on that grid.

    The Rotation field is valid with all of the methods, and allows you to specify the degrees you want to rotate.

    You could also click the Dig button to digitally select a point and the rotate direction. Minex will fill in the
