Edit Panel

The function is identical to the section definition portion of Place Panel function. It is used to edit properties of the section of the panel after the panel has been completed. The precedence can be set by either picking from the list, or screen picking.

Panel name: This is a required field.
Panel start: This is an optional field. The Underground Timing routine have an option for start date that usually makes this field unnecessary. This field can delay the start of a panel independently of the plan start date.
Easting: The easting coordinate value of the first picked point when the panel was placed.
Northing: The northing coordinate value of the first picked point when the panel was placed.
Azimuth: The azimuth from the first to the second picked points when the panel was placed.
Entry Width: This is used to calculate face feet/meters of advance. This should be set to the width of the panel when working with longwall panels to get the correct advance down the panel.
Prompt for coal qualities: A check in this box brings up the Define panel Attributes dialog box.

Prompt for retreat options: The following prompts appear that allow for a second polygon that specifies a second area that can be retreat mined separate from the area mined on the advance. This additional polyline must be closed and can be totally contained in the advance polyline, overlap, or be outside. When the polyline overlaps two options exist: the extraction ratio for the area contained in the advance polyline and the area outside of the advance mining polyline.

Command Line Prompt:

Pick a polyline representing a shape of the retreat area:
Enter the extraction ratio for remaining pillars: .25
Enter the extraction ratio for COAL outside the panel: 0

Retreat Extraction: Any entry in this box other than the default zero will place a second mining panel that can be scheduled on the retreat back through the panel.
Owner: A single owner's name can be assigned to the panel.
Precedence: This box gives the opportunity to set fixed scheduling relationships. Any panels selected must be completed before this panel can start.

Advance Difficulty Factor: A value or a grid can be used to provide difficulty factor input for advance mining in the panel.
Retreat Difficulty Factor: A second value or grid can be specified for retreat mining independent of the advance mining difficulty rate.
