Hole Properties

Blast pattern to which the hole belongs. Read-only.

A blast pattern is a group of holes that belong to any charge pattern. Use a blast pattern to group holes from separate charge patterns so that the holes can be blasted at the same time.

Charge pattern to which the hole belongs. Read-only.

A charge pattern is a group of holes with the same drill diameter that belong to any drill pattern. Use a charge pattern to group holes that be charged in the same way. A charge pattern can only have one charge rule.

Use the collar appearance to indicate a different property of the hole; for example, the hole collar angle.

Colour of the hole collar flag, which is an additional circle drawn at the collar of a hole. Enter a colour name or click the drop-down arrow to display a colour picker.

Use a collar flag to indicate that a different action is required for the hole; for example, if the hole needs to be a probe hole.

Initiation pattern to which the hole belongs. Read-only.

An initiation pattern is a group of holes belonging to any blast pattern or charge pattern. Use an initiation pattern to group holes for initiation sequencing.

Whether the hole is abandoned. Read-only.

An abandoned hole is no longer intended for drilling, dipping, charging or timing. As-built data can still be added to an abandoned hole.

Comments added when entering load data via BlastPad. Read-only.

Mine block to which the hole belongs.

Use the mine block to specify domains of planning or geological regions in the mine; for example, North Cut-back 3 or High Grade Ore.

Reactive ground describes geology that undergoes spontaneous exothermic reactions when exposed to air or nitrates. A hole is reactive if it intersects this geology. To change this property, see Change the Reactive Status of Holes.

Reporting pattern to which the hole belongs. Read-only.

A reporting pattern is a grouping of holes for purposes other than that used by drill patterns, charge patterns, blast patterns or initiation patterns. For example, use a reporting pattern to group holes from multiple drill patterns that were previously 'cut-off'.

The additional depth drilled below the intended floor or grade level of the blast. The purpose of subdrilling is to ensure that the entire rock mass is adequately fragmented, avoiding any unbroken rock at the bottom of the blast hole. Subdrill is measured as the extra length added to the drill hole below the planned excavation or bench level.
