Waste Tonnage Calculator
Audit independently classified actual waste bank volumes/dry densities with unknown survey blocks, not ore-fraction block tonnage or loose swell assumption. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
Bank volume and matched dry bulk density give a dry-mass inventory for classified waste.
Bank volume and matched dry bulk density give a dry-mass inventory for classified waste.1
Unknown surveyed blocks need separate accounting rather than a zero-mass interpretation.
When to use Waste Tonnage Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
How to use Waste Tonnage Calculator and understand its results
- Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
- Enter observedWasteBankVolumesM3, observedMatchedDryBulkTonnesM3, knownWasteVolumeFlags, using the field meanings and rules below, then run the tool.
- Read knownWasteDryTonnes, unassessedWasteBlockCount. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedWasteBankVolumesM3 | Observed waste bank volumes m3 | list of number | Required |
| observedMatchedDryBulkTonnesM3 | Observed matched dry bulk tonnes m3 | list of number | Required |
| knownWasteVolumeFlags | Known waste volume flags; binary 1 means the matched observation is known, 0 means unknown | list of number | Required |
Use aligned nonnegative volumes, positive dry densities in tonnes/m³ and binary volume-known flags. Multiply volume×density for each block, sum only known blocks and count unknown ones. Placeholder data still must satisfy value bounds.
knownTonnes=Σ_known volume_i density_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| knownWasteDryTonnes | Known waste dry tonnes | number |
| unassessedWasteBlockCount | Unassessed waste block count; unresolved records kept separate from known results | number |

}Limitations and assumptions
Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
