Calculation Rules
| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
|---|---|---|---|---|---|
| delivery_reconciliation | all inventory rows | Keep each actual attributable exchange total in its declared unit per declared reference flow. Reconcile receipts, stock changes, returns, internal batch transfers, installed material, real losses and outgoing streams. Separate independent accepted facilities by actual direct subdivision before reporting one delivery; no default mix, per-facility mass, density, loss or life. | cp_acceptance; cp_earth; cp_blast; cp_batch; cp_support; cp_civil; cp_install; cp_utilities; cp_water; cp_waste | same-unit exchange total per declared reference flow | wa-ground-control-2019; epa-concrete-washout-2012 |
| preserve_numerator_units | electricity_lv_cn; electricity_mv_cn; electricity_other; diesel; treated_process_water; low_voltage_cable; road_freight | Maintain the complete facility denominator. Electricity kWh becomes MJ using 3.6 MJ/kWh; L becomes m3 using 0.001 m3/L; road payload t times actual km gives t*km, with 1000 kg/t. For mass/volume/count/length relations retain actual measured/certified same-state density, unit mass or geometry with units and uncertainty. Public reference properties remain unchanged. | cp_utilities; cp_water; cp_transport; cp_install | same-unit exchange total per declared reference flow | |
| asset_attribution | excavator_asset; drill_asset; crane_asset; formwork_plywood; steel_mesh | For included reusable asset manufacture, multiply actual same-configuration asset mass/count by the evidenced dimensionless current service share. Current and total service have matching units and real supported boundaries; retain all prior and other uses so cumulative shares do not exceed one. Permanent delivered material is its actual full included quantity once. This attributes an input asset, not a conversion of the facility reference to kg. | cp_assets | attributed asset input per declared reference flow | |
| environmental_quantification | fossil_co2; nitrogen_monoxide; nitrogen_dioxide; pm25; pm_2_5_10; pm_unspecified; groundwater_abstraction; freshwater_release; seawater_release | Use supported external substance/fraction release or resource withdrawal totals, preserving actual medium and units. Air mass requires real concentration times corresponding flow/time or actual activity times an independently supported species/control factor. Water pollutants require actual concentration times corresponding actual discharge volume with units. Fuel carbon balance needs measured fossil fraction/oxidation; it supplies no NOx split or PM factor. Retain nonoverlapping fractions and water destinations; missing evidence is unknown, not zero. | cp_air; cp_water; cp_utilities | supported release or withdrawal per declared reference flow | ifc-mining-2007 |
| joint_works_attribution | mine_excavation; reference_mine_facility | Use actual separate stage totals wherever causal construction and production are observable. For any inseparable jointly beneficial work, apply the reviewed actual causal driver with all recipients and denominator documented in cp_allocation; retain exported development ore as a real output and do not credit hypothetical avoided mining. Later mineral inventories must reference the resulting construction burden once. | cp_allocation; cp_earth; cp_acceptance | reviewed attributed construction exchange total per declared reference flow | platreef-shaft-case-2025 |
Data Quality Requirements
| requirement_id | Applies to | Requirement | Evidence |
|---|---|---|---|
| entity_complete | reference_mine_facility | Retain the entire accepted functional scope and all real route stages, geometry, configuration and tests; distinguish actual completed work from proposed mine expansions. | cp_acceptance; as-built survey and asset/interface schedule |
| identity_and_units | all inventory rows | Verify each actual material/substance/component state and public reference property/unit; retain geography/voltage/medium/CAS/fossil/size conditions. Blank UUIDs require row-level resolution before deployment as confirmed identities. | supplier/assay/site evidence and public identity references |
| time_and_site | dataset | Cover the real construction and test campaign at the actual site, including returns, rework, dewatering and temporary operation; explain subcontract gaps and unmeasured intervals. | all cp records with dates, calibration and coverage |
| assets_and_joint_work | excavator_asset; drill_asset; crane_asset; formwork_plywood; mine_excavation | Document supported total asset service and all attribution recipients; review unknown denominator and actual/forecast ore interfaces, retaining cumulative share conservation and sensitivity. | cp_assets; cp_allocation; complete persistent ledgers |
| environmental_coverage | site_utilities; construction_waste | Track actual external air/liquid pathways separately from workplace exposure and waste transfer. Add significant real geological gas, dissolved species, land and noise/vibration coverage with correct metrics; declare measurement/identity gaps rather than asserting total coverage. | cp_air; cp_water; cp_waste; location/time and method evidence |
9. Validation Rules
| rule_id | Applies to | Rule | source_ids |
|---|---|---|---|
| v_reference | reference_mine_facility | Require one complete physically accepted facility and all relevant qualifiers; reference name and output-row name match exactly, output is 1 item and every collection/inventory denominator is per declared reference flow. A count basis alone does not demonstrate applicability or interchangeable performance. | |
| v_route | all inventory rows | Check the actual shaft/drift/pit/headframe/station route and all significant materials, mixtures, permanent devices, plant and tests. Mark a conditional exchange absent only with evidence. Actual unlisted chemistry/components get separate atomic rows; mixture alternatives and internal transfers are not duplicate purchases. | |
| v_units_identity | all inventory rows | Check actual supply gates, country/voltage, substance/CAS/origin, medium/submedium, particle size and reference property/unit relations. No false conversion from Volume/Length/Count to Mass, unresolved reference product UUID remains a declared candidate gap, and public official Chinese names remain aligned. | |
| v_balances | mine_excavation; site_batching; site_utilities; construction_waste | Reconcile actual excavation/reuse/export, each fresh mixture, fuel/stock, liquid inputs/outputs and waste disposition. Distinguish natural withdrawal, consumption, treatment transfer and direct recipient release; PM fractions and molecular NO/NO2 cannot be replaced by totals/equivalents or workplace concentrations. | |
| v_allocation | dataset | Verify one persistent cross-project asset ledger and supported share denominator; cumulative manufacture attribution at most one. Review facility/ore-production joint activities and prevent mineral models counting the same development burden again. Unproved mathematical/causal relationships remain review. | |
| v_coverage | dataset | Report performed/skipped checks, source-bound measurement/identity gaps, uncertainty and stage coverage. Neither accepted construction nor a passed structural check grants methodology/scientific approval. Do not label foreground as complete cradle-to-gate, whole life or total environmental coverage without independent complete evidence. |

| downstream_use | secondary_dataset; background_dataset |
