- SHOTPlus™ Variant:
- Surface
- Version:
- 6.14.13 (Beta) and 6.14.1 (Production).
- KBA Summary:
- This Knowledge Base Articles (KBA) describes the different volume states available in SHOTPlus™.

**Summary**

SHOTPlus™ calculates volumes on a hole-by-hole basis. Depending on the information available there are three different 'states' that SHOTPlus™ uses to describe the volume for a hole. These are:

**Design Volume**- The volume of a hole considering it's design location and parameters.**Updated Design Volume**- The volume of a hole considering recorded measurements, and the intended Grade R.L. of the hole.**Drilled Volume**- The volume of a hole considering information recorded by a drilling machine, and the 'Drilled' length of the hole.

**Hole State Volumes**

**Design Volume**

The volume of a hole considering it's design location and parameters. Design volume aligns with BlastIQ™ Design volume.

**Design Volume Formula**

Design Volume = ((Hole Collar Area + Hole Toe Area)/2) x h

Where:

- Hole Collar Area = A hole's collar area calculated from a voronoi tessellation using design collar coordinates.
- Hole Toe Area = A hole's toe area calculated using a voronoi tessellation using design toe coordinates
- h = Collar Z - Grade Z.
- If Grade Z = 'null' then h = Collar Z - Toe Z.

* * Information

This calculation is affected by the SHOTPlus™ Volume Calculation Mode in use. If not using '**Full Hole Voronoi**' the toe area will not be calculated.

**Updated Design Volume**

The volume of a hole considering the hole best available available information and intended Grade R.L.. Where no measurements are recorded for a hole, the 'Updated Design' for a hole will be equal to the 'Design' volume. Unless otherwise stated 'Updated Design' volume is the default volume used by SHOTPlus™ outside the Volume Overview tool. 'Updated Design' volume aligns with BlastIQ™ Best Available Viable Volume.

**Updated Design Volume Formula**

Updated Design Volume = ((Hole Collar Area + Hole Toe Area)/2) x h

Where:

- Hole Collar Area = A hole's collar area calculated from a voronoi tessellation using the best available collar coordinates.
- Hole Toe Area = A hole's toe area calculated from a voronoi tessellation using the best available toe coordinates.
- Best available toe coordinates calculated using:
- best available collar coordinates.
- best available angle and bearing.
- the first (from top to bottom) length available out of:
- adjusted design length
- design length
- drill actual length
- measured actual length

- Best available toe coordinates calculated using:
- h = Collar Z - Grade Z.
- if Grade Z = 'null', then h = Collar Z - Toe Z.

**Best Available**

For 'Updated Design' volume calculations 'best available' is considered the first available from:

- Measured;
- Drilled; or
- Designed.

* * Information

This calculation is affected by the SHOTPlus™ Volume Calculation Mode in use. If not using '**Full Hole Voronoi**' the toe area will not be calculated.

**Drilled Volume**

The volume of a hole considering the drilled information. If a hole does not have Drilled information, it will not have a 'Drilled Volume'. 'Drilled Volume' is available in the Volume Overview tool. 'Drilled volume' is not available in BlastIQ™.

**Drilled Volume Formula**

Drilled Volume = ((Hole Collar Area + Hole Toe Area)/2) x h

Where:

- Hole Collar Area = A hole's collar area calculated from a voronoi tessellation using the best available coordinates.
- Hole Toe Area = A hole's toe area calculated from a voronoi tessellation using the best available toe coordinates.
- Best available toe coordinates calculated using:
- Best available collar coordinates
- Best available angle and bearing
- Drilled Length

- Best available toe coordinates calculated using:
- h = Collar Z - (Toe Z - sub-drill)
- If 'Include sub-drill in volume calculations' is turned on h = Collar Z - Toe Z.

**Best Available**

For 'Drilled' volume calculations the 'best available' is considered the first available from:

- Drilled; or
- Designed.

* * Information

This calculation is affected by the SHOTPlus™ Volume Calculation Mode in use. If not using '**Full Hole Voronoi**' the toe area will not be calculated.
