Tritronics
Create a mapfile in the Tritronics DrillNav Plus Mapfile format
The Tritronics option to create a mapfile in the Tritronics DrillNav Plus Mapfile format. The blast hole objects are placed in the CSV mapfile (extension
.map
) as point objects 'PO' records.
The report consists of PO, hole name, easting, northing, bottom RL, instruction field, hole bearing (from bottom to top), mast angle (from vertical) and the top RL.
Note To include the top RL in the report, you must check the Include top of hole elevation check box on the Tritronics Mapfile Parameters panel.
It is also possible to add line objects (strings). The information about these objects will appear in the report after the point object information and is in the following format:
line type, easting and northing
where line type is one of:
- LS - start of line
- LN - middle of line
- LE - end of line
To use this option, the holes and the boundary containing the holes must be displayed on the screen. This mapfile can be placed in any directory.
Note The Tritronics option does not support the Input intervals method.
Instructions
- Select Open Pit menu
- Select Hole Design submenu
