This command allows you to modify and playback the surface
sequence history generated by several Carlson commands such as
Design Bench Pit. The surfaces can be either grid or triangulation
files. The command initially displays a list of surface files in
the sequence. You can add more surfaces, modify surface colors or
change the surface order. The Add and Edit functions have a dialog
to set the surface file name, description and color for the step.
There are also settings for the optional pit and perimeter
polylines. The pit polyline is the base of the pit where the cut
slopes start. The perimeter polyline is the limit of the pit where
the cut slope ties into the ground surface. When the Surface
History has the pit and perimeter polylines assigned, then the
Surface Mine Reserves command has an option to use the Surface
History to report strata quantities for each step in the
history.
When editing is complete, pick the OK button which brings up the
playback 3D viewer window.
In the right side of the Viewer
window, there are buttons allowing you to move from step to step in
a surface sequence. On each step the surface displayed has
elevations of the surface assigned for that step and the color of
the last surface when the elevation at a particular location
changed. For example the unaffected regions will have the color
assigned to original ground surface. The Run Speed controls the
rate of showing the surface with the Run button.
The blue circle icon with yellow dot represents the sky and sun
position. You can move the yellow dot to change the shading for the
sun. There are sliders to control the brightness of the ambient and
sun lighting. The Display Axis toggle shows an X/Y/Z axis icon in
the scene.
The zoom button activates zoom mode, where if you hold left mouse button and drag the mouse pointer up or down the picture zooms out or in correspondingly. In the rotate mode, the horizontal drag rotates the X axis (around Y), the vertical drag rotates the Y axis around X. The circular movement along the periphery of the picture rotates picture around the Z axis.
When pan button used, the picture will pan if mouse is dragged with the left button pressed.
The shade button turns the shading of the surface on or
off.
The camera button saves an image file of the current
view.
This GSQ file can be used in Surface Mine Reserves to automatically calculate the quantities by bench for the pits with highwalls.
