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 bottom part of the window there
is a row of buttons allowing user 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 row of buttons at right controls the view response to mouse drags and the shading. 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.
This GSQ file can be used in Surface Mine Reserves to automatically calculate the quantities by bench for the pits with highwalls.
