Add Drillhole

On the Mining | Round Editor tab, in the Drillholes group: Click Add Drillhole to add a drillhole to the round.

When the Round Editor tab is active, the Add Drillhole tool can be used to add a drillhole to the round being edited. You can also use this tool to successively add multiple holes. When the tool is activated, the below window will appear.

In the Add Drillhole form, set the parameters of the hole you want to add:

Hole Details

Diameter

The diameter of the drillhole. Hole diameter is a fundamental factor in blast geometry since it affects the results that can be achieved from blasting.

Length

The length or depth of the hole.

Subdrill

If blastholes are to be drilled below the design length, enter the length of sub-drilling required. When a subdrill value is specified, the total length of the hole (Length field reported in the Drillholes List & Properties window) will be equal to the Length + Subdrill specified in the Add Drillhole form. Note that Subdrill is normally positive (so the hole extends below floor level). Negative values are not allowed. See: Sub-Drilling

Hole Type

Select the type of the hole you want to add. See: Hole Types

Show practical damage zone

Select the Show practical damage zone check box to display a damage zone circle around the hole(s) being added to a round. The Practical Damage Zone of each hole can be displayed for holes which possess a Radius of Damage value.

Specify a practical radius of damage value. This value represents the radius of the damage zone circle and will be assigned to the Radius of Damage property of each drillhole that is added.

Radius of Damage

Specify a practical radius of damage value. This value will be assigned to the Radius of Damage property of each drillhole that is added.

Select this check box to show a damage zone for the hole and specify a value.

Hole Orientation

Dip

Enables rotation of the drillhole about the X-axis in the Round Editor window. Positive values will orient a drillhole downward, negative values will orient a drillhole upwards. This field will accept values between of -90 to 90 degrees.

Bearing

Enables rotation about the Y-axis in the Round Editor window. This field will accept values between 0 to 360 degrees.

Charge Details

Charge type

Optionally, double click in this field to select a charge template for the drillhole(s) being added to the round. See: Assign Charge Template

Annotate distance to perimeters

Select this check box to display dynamic annotations which report distances from a hole to the bounds of the round.

OK

Finally, click OK to generate the new hole.
