Blast Powder Factor Calculator
Retrospective measuredpowderfactoractualconsumedkg/independentlysurveyedbrokenm³. Not selected charge quantity, blast recipe or safe explosive/site authorization.
Description
A retrospective powder factor compares recorded consumed mass with independently surveyed broken-rock volume.
A retrospective powder factor compares recorded consumed mass with independently surveyed broken-rock volume.1
This tool calculates that observed ratio without selecting a future explosive quantity.
When to use Blast Powder Factor Calculator
This tool calculates that observed ratio without selecting a future explosive quantity.
How to use Blast Powder Factor Calculator and how it works
- Prepare recorded consumed explosive mass kg, independently measured broken rock volume cubic meters, using the input definitions and matching units below.
- Enter the required fields and run Blast Powder Factor Calculator.
- Read result.value using the units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualRecordedConsumedExplosiveMassKg | Actual Recorded Consumed Explosive Mass Kg. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
| actualIndependentlyMeasuredBrokenRockVolumeCubicMeters | Actual Independently Measured Broken Rock Volume Cubic Meters. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Require nonnegative recorded consumed mass in kg and positive independently measured broken volume in m^3. Divide mass by volume and return retrospective kg/m^3. The ratio describes supplied records and does not prescribe a future quantity or certify operation safety.
observedPowderFactorKgPerM3=recordedConsumedKg/measuredBrokenM3 Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Retrospective observed mass-per-broken-volume ratio in kg per cubic meter. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
