Range Diagram

The Range Diagram command is an interactive tool that displays graphics which are dynamically updated when adding or editing values in the spreadsheet text below. This is a quick and easy way to find parameters such as pit width, or to size a dragline to fit the geology. Methods of mining include Side Cast, Dozer Push, Extended Bench and Spoil side mining. Output includes both drawing the sections in CAD and printing out reports as PDF files, where each step is a separate page. Each option is detailed below.

Spoil Side Example
Input Parameters


  1. Extended Bench Settings. This option has two settings to set the Steepened Angle of repose for the pushed material, and to set the width that the bench is extended horizontally.

  1. Dozer Push Settings. These four settings control the operation of dozer push. The Steepened Angle is the angle of repose of the pushed material. The Doze Angle is the slope to push down to the bench level. The Doze Depth sets how far down to push from the top. And finally, the Doze Width sets the bench width of the flat dozer bench.
  2. Spoil Side Bench Settings. These settings control the spoil side bench dimensions. The Steepened Angle sets the angle of repose of the bench material. The Bench Height sets the height of the bench from the pit floor. The Spoil Offset sets the width of the bench horizontally from the spoil.



Dragline and Seam Data
Left Key Cut

  1. Cut Width: The width is entered in to set the horizontal distance of the bottom of the Key cut.
  2. Cut Angle (degree): This is the angle of the key cut highwall.
  3. Dragline Offset: This is the distance for the dragline center-pin from the crest of the highwall. This moves the dragline from the initial position to get the Key cut moved.
  4. Add to Spoil: This option determines whether to spoil or not. If it is hauled away by other equipment, then this should be off. If it is spoiled with the dragline, then it should be on.

 


Graphics Window
: The ground surface is color green.

Output: The output shows up in the lower right. It displays the area of the cuts and fills of all the material moved, and the dragline that moves it.

Draw: This option will draw the steps in CAD as polylines with fill. It will prompt for the starting point in CAD to draw them. Exit the command to see them in CAD. Here is an example of what it draws, their colors and entities.
Report
: The report button will create a multipage PDF document where each step in the section will be on a separate page. Then at the end, one final page will show all the steps together with the finished section.
