Blast Energy Factor Calculator
Retrospective actual independently measured total energy/broken volume energy factor, no energy-density recipe, explosive quantities or detonationplanning inferred.
Description
A retrospective energy factor compares independently recorded released energy with measured broken-rock volume.
A retrospective energy factor compares independently recorded released energy with measured broken-rock volume.1
This tool calculates that observed ratio without inferring explosive quantities or operational settings.
When to use Blast Energy Factor Calculator
This tool calculates that observed ratio without inferring explosive quantities or operational settings.
How to use Blast Energy Factor Calculator and how it works
- Prepare retrospectively recorded total released energy, independently measured broken rock volume, using the input definitions and matching units below.
- Enter the required fields and run Blast Energy 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 |
|---|---|---|---|
| actualRetrospectivelyRecordedTotalReleasedEnergy | Actual Retrospectively Recorded Total Released Energy. Use the units and matching context stated in the calculation below. | number | Required; nonnegative; finite; other constraints below |
| actualIndependentlyMeasuredBrokenRockVolume | Actual Independently Measured Broken Rock Volume. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Require nonnegative retrospectively recorded released energy and positive independently measured broken-rock volume. Divide for energy per volume using the supplied matched units. No energy density, explosive mass, prospective settings or detonation procedure is inferred.
observedEnergyFactor=recordedReleasedEnergy/measuredBrokenVolume 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 energy per measured broken volume in the supplied units. | 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.
