Hole Types - Hole Type Tolerances

Backfill and Redrill tolerances are used to define which holes are treated as 'Backfill required' or 'Redrill required'. Where a hole's Actual length falls outside of the defined tolerance it will be flagged as 'Backfill required' or 'Redrill required'.

E.g. a hole with a with a Design length of 10 m and a backfill and redrill tolerance of 0.5 m will be flagged as Backfill required when the Actual length is greater than or equal to 10.6 m, and as Redrill required when the Actual length is less than or equal to 9.4 m.

Behaviour triggers:

• Backfill required or Redrill required in SHOTPlus™.
• Backfill required or Redrill required in BlastIQ™ Mobile.
• Drilling accuracy reporting in SHOTPlus™ Analytics view.

Wet state tolerance is used to define how much water a hole can contain before it is considered Wet. When the amount of water recorded for a hole falls outside of the defined tolerance it will be flagged as Wet.

E.g. a hole with a Wet state tolerance of 0.1 m will be flagged as Dry until the amount of water recorded for that hole is equal to or greater than 0.2 m.

Behaviour triggers:

• Wet tag in SHOTPlus™
• Wet tag in BlastIQ™ Mobile
• Application of Wet Charging rules in SHOTPlus™
• Application of Wet Charging rules in BlastIQ™ Mobile

Collar XY tolerance is used to defined how far the Actual collar coordinates of a hole can be from the Design collar coordinates before it is considered Outside of tolerance.

E.g. a hole that is drilled 0.4 m from a hole with a Collar XY tolerance of 0.3 m will be considered Outside of tolerance.

Behaviour triggers:

• Drilling variance reporting in SHOTPlus™ Analytics view.
• Drill Collar Deviation reporting in BlastIQ™ Insights.

Overdrill and Underdrill are separate from Backfill and Redrill tolerances, and are used to report on variation between Design length and Actual length. Where a hole's Actual length falls outside of defined tolerance it will be flagged as 'Overdrilled' or 'Underdrilled'.

E.g. a hole with a with a Design length of 10 m and a Overdrill and Underdrill tolerance of 0.5 m will be flagged as Overdrilled when the Actual length is greater than or equal to 10.6 m, and as Underdrilled when the Actual length is less than or equal to 9.4 m.

Behaviour triggers:

• Drilling accuracy reporting in SHOTPlus™ Analytics view.
• Hole depth variance reporting in SHOTPlus™ Analytics view
• Drill Length Deviation reporting in BlastIQ™ Insights.
