Overview

This section describes the options under the Blast Hole Layout submenu. This submenu is primarily used at coal sites.

The Blast Hole Layout options allow you to generate blastholes between two surfaces. The first surface, that is, the collar surface, must be a triangulation. The other, that is, the target surface to which the holes are being projected, may be a triangulation or grid mesh model. Up to four intersecting surfaces (or grid meshes) may be specified. The file names of the intersecting surfaces may not exceed 8 characters as the file names are used for the names of the points where holes intersect a surface.

Note

The system assumes that each nominated intersecting surface is below the previously indicated surface, that is, has a decreasing Z value.
