How to import blast holes into SHOTPlus Underground

NOTE: SHOTPlus UG is not designed to support manual creation of rings. Holes can be imported using several methods and adjusted as required.

1. SHOTPlus Underground supports the import of data from 4 main file types.

  • .txt
  • .DXF
  • .Str – string file
  • .dtm – Digital terrain model – from Surpac or similar

Once a hole or ring design has been imported, SHOTPlus can be used to adjust the position of the hole (s) and edit loading details.

2. Several options related to the data import should be set up prior to the import of your hole data. These settings will be used to orientate the direction of the blast holes in relation to the grid reference within SHOTPlus Underground.

The settings can be found under. Edit – Edit blast properties – Underground settings.
