Explosive Quantity Per Hole Calculator

Retrospective actual single-hole inventory reconciliation only, returns separate/signed mismatch retained. No volumetric charge calculation, explosive preparation, loading recipe, detonationscheduling or site safety approval.

Description

A retrospective per-hole material ledger compares inventories and separately recorded returned material.

A retrospective per-hole material ledger compares inventories and separately recorded returned material.1

This tool retains the signed reconciled consumption without calculating a planned charge from geometry.

When to use Explosive Quantity Per Hole Calculator

This tool retains the signed reconciled consumption without calculating a planned charge from geometry.

How to use Explosive Quantity Per Hole Calculator and how it works

  1. Prepare recorded pre hole explosive inventory kg, recorded post hole explosive inventory kg, separately recorded returned mass kg, using the input definitions and matching units below.
  2. Enter the required fields and run Explosive Quantity Per Hole Calculator.
  3. Read result.signedInventoryReconciledHoleConsumptionKg using the units, signs and ordering explained below.
  4. Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
Input fieldMeaningValue typeRequirement
actualRecordedPreHoleExplosiveInventoryKgActual Recorded Pre Hole Explosive Inventory Kg. Use the units and matching context stated in the calculation below.numberRequired; finite; other constraints below
actualRecordedPostHoleExplosiveInventoryKgActual Recorded Post Hole Explosive Inventory Kg. Use the units and matching context stated in the calculation below.numberRequired; finite; other constraints below

Require nonnegative recorded pre-event inventory, post-event inventory and separately recorded returned mass in kg. Subtract post inventory and returned mass from pre inventory, retaining any negative discrepancy. Return signed retrospective consumption in kg; records must use a consistent accounting convention so returns are not counted twice. No planned quantity or loading calculation occurs.

signedConsumptionKg=preInventoryKg-postInventoryKg-returnedKg

Apply the input ordering, units and branch conditions stated above.

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.

Alternative or Complementary methods

Use Explosive Quantity Per Blast Calculator for a complementary operation: A retrospective blast-event ledger can total already reconciled per-hole consumption records.

Use Blast Powder Factor Calculator for a complementary operation: A retrospective powder factor compares recorded consumed mass with independently surveyed broken-rock volume.
