Scope and Applicability This PCR governs the construction and accepted physical delivery of non-building mining facilities: winding shafts and towers/headframes, mine tunnels, drifts and declines, and mine loading/discharging stations with their integral civil, support and permanent installation interfaces. An actual engineered open-pit access/initial mine-working facility is also in scope when its separately accepted physical extent and mining function are demonstrated. These are facilities associated with mining, not a construction service or a tonne of ore. Sources: `unsd-cpc-3-2025`; `wa-ground-control-2019`. A dataset defines one complete facility or integrated mine-access/materials-handling delivery unit from actual design, as-built survey and acceptance records. Underground access, headframe and loading-station routes must not be replaced by a simpler unrelated structure. A contract section is a reference entity only if its complete functional interfaces and independently accepted extent are documented; do not choose an arbitrary metre of shaft, construction shift or minor component to bypass missing work. Exclude buildings, public transport tunnels, independent power plants and manufacturing/chemical plants, independently delivered roads/pipelines, machinery/material manufacture sold separately, routine ore extraction/processing and mining services. Include genuinely integral mine-access and loading interfaces, with an asset/interface schedule preventing overlap. For rehabilitation, disclose retained assets, condition, removal and new work; do not charge their original manufacture again without an explicit attributed prior-asset boundary. The principal boundary is actual construction-to-accepted-handover. Bought-material/equipment production, external transport, site construction, subsequent mine operation/maintenance/renewal, and closure/demolition/disposition are distinct stages. Upstream burden is linked only from verified compatible datasets; the foreground alone establishes neither complete cradle-to-gate nor whole life. Literature supplies route context, not universal recipes, dimensions, equipment necessity, quantities, lifespan, loads, emissions or compliance approval. ## 2.

Reference Flow | Field | Value | | --- | --- | | What | Provide the defined physical mine-access/winding/loading facility ready for its documented function at handover. | | How much | One complete accepted delivery unit; surveyed shaft depth/diameter, drift length and cross-section, decline gradient, initial pit extent, tower height/geometry, station extent and actual handling interface/capacity are required where relevant, never defaults. | | How well | Actual geotechnical, structural, hydraulic, ventilation and mechanical/electrical acceptance criteria and test conditions under cp_acceptance; retain ground/water conditions and installed support. Do not infer mining licence, production performance or universal safety approval. | | How long or cycle | One actual construction/commissioning-to-handover cycle with start/end/test dates.

Here item is a display alias for the public Item(s) counting unit. Measured length/area/volume/capacity characterizes the same complete facility; a different facility or route is not interchangeable solely because its count is one. No mass or service duration is implied. ## 4. Measurement and Unit Rules | rule_id | Applies to | Required property | Required unit | Rule | | --- | --- | --- | --- | --- | | reference_count | reference product | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | item | Use cp_acceptance to confirm one complete accepted facility with the same documented configuration and extent. Every row is per declared reference flow; measured geometry and capacity are qualifiers, not alternative denominators.

Count/volume/area/length to mass requires actual same-lot unit mass, density, areal mass or geometry and associated material density. No generic 1 kg machine or default density/recipe is used. | | fresh_volume | purchased_concrete; purchased_shotcrete; purchased_grout; site_concrete; site_shotcrete; site_grout | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 | Use actual measured fresh received/batched/placed volumes, preserving batch formulation, entrained air, returns, rebound and hydration state. Mass conversion requires corresponding fresh density; do not substitute hardened volume, dry powder mass or a whole-works mass. | | treated_water_mass | treated_process_water | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Preserve the public treated-water Mass/kg identity and obtain actual same-water measured density at the documented temperature and composition when raw records are volumetric. Keep the raw volume balance; no default density. | | water_state | untreated_supplied_water; groundwater_abstraction; freshwater_release; seawater_release; dewatering_transfer; washout_liquid | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 | Meter each liquid stream at its actual source/destination and retain raw volume balance. treated_process_water has a public Mass property: preserve it using independently measured same-water density, not a rewritten Volume identity. Resource withdrawal, supplied water, internal reuse, waste transfer and direct release remain distinct. | | energy_property | electricity_lv_cn; electricity_mv_cn; electricity_other | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Preserve the Net calorific value reference property and energy unit group. Convert kWh to MJ with 3.6 MJ/kWh; this does not assign a fuel heating value. Raw fuel litre-to-kg or kg-to-MJ conversions need actual fuel density/heating value and state. | | component_length | hdpe_drain_pipe; low_voltage_cable | Length `838aaa23-0117-11db-92e3-0800200c9a66` | m | Retain actually received/installed length and actual cross-section, cores, wall thickness, joints and offcuts. Public cable Length is not rewritten as Mass; any supplemental mass needs the actual matching measured/certified unit mass. | | freight_work | road_freight | Goods transport (mass*distance) `838aaa20-0117-11db-92e3-0800200c9a66` | t*km | Use actual payload in tonnes multiplied by actual leg distance in km, retaining empty-return and allocation conditions under cp_transport; 1000 kg = 1 t, with no default haul distance. | ### Flow-property and unit-group support relations | Flow property | Unit group | Public reference unit | | --- | --- | --- | | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` | kg | | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | Units of volume `93a60a57-a3c8-12da-a746-0800200c9a66` | m3 | | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | Units of energy `93a60a57-a3c8-11da-a746-0800200c9a66` | MJ | | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | Units of items `5beb6eed-33a9-47b8-9ede-1dfe8f679159` | Item(s) | | Length `838aaa23-0117-11db-92e3-0800200c9a66` | Units of length `838aaa22-0117-11db-92e3-0800200c9a66` | m | | Goods transport (mass*distance) `838aaa20-0117-11db-92e3-0800200c9a66` | Units of goods transport `838aaa21-0117-11db-92e3-0800200c9a66` | t*km | ## 5. System Boundary ### Boundary Abstraction | Field | Value | | --- | --- | | declared_starting_condition | Actual surveyed site, geology, groundwater and prior/retained mine assets; defined supplier material/equipment gates and temporary access/dewatering/ventilation interfaces before construction. | | starting_condition_role | foreground construction starting interface; upstream manufacture and prior assets are separate | | product_classification_scope | Non-building mining facilities, CPC 3.0 53261 context; integral structures require a non-overlapping applicability decision, not automatic inheritance of all mine assets. | | recursive_input_rule | Incoming same-category facility or retained mining component is recorded at its actual interface with attributed prior burden and compatible dataset; do not recursively reproduce its construction or convert a whole mining operation into a new construction input. | | upstream_dataset_requirement | Link actual material/component/plant production, external freight and waste treatment only where supplier, geography/time, product state, configuration, property and boundary match. Report unlinked burdens and check overlap explicitly. | | disclosure | Disclose construction phases and route, all starting/ending gates, prior assets, subcontract interfaces, upstream coverage, temporary plant attribution, ore-development separation and later phases excluded or separately modelled. | | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | construction_delivery | dataset | Collect actual enabling, opening/excavation, support/lining, civil structures, permanent installation and all testing/rework to the documented handover. Mechanical/raise-bore/blast routes and open-pit geometry are conditional on real works. The Platreef case is route context, not a required shaft size or timetable. | `unsd-cpc-3-2025`; `wa-ground-control-2019`; `platreef-shaft-case-2025` | | stage_interfaces | all inventory rows | Separate purchased mixtures from their site-batched alternatives and keep internal batching-to-installation links. Do not count powder/aggregate manufacture twice through both ingredients and a purchased complete mix. Preserve external transport and site operation overlap checks for complete subcontract services. | `epa-concrete-washout-2012` | | mining_transition | mine_excavation; handover | Separate facility construction/development from routine mineral extraction, processing and later mine ventilation/dewatering. Where construction exposes recoverable ore, preserve actual assay, mass, destination and contemporaneous construction/production activities; add each real ore output separately and review allocation. Do not treat saleable development rock automatically as waste or all production as construction. | `platreef-shaft-case-2025`; `ifc-mining-2007` | | later_life | dataset | Operation/maintenance, support renewal, later mine expansion, closure, demolition, long-term drainage and final disposition are outside the core handover result. If requested, model them as distinct evidenced stages with real service periods, quantities and destinations; never assume a universal life or declare whole life from this core. | `ifc-mining-2007` | | environmental_routes | site_utilities; construction_waste | Identify actual abstraction, pumped inflow, rainfall, process water, reuse, evaporation, liquid transfer and recipient-specific release. Add significant real gas, dissolved substance and size-specific particulate exchanges separately using matching public identities where verified. Land transformation, noise, vibration and occupational dust metrics require actual location/time and appropriate methods; absence of a row is not zero impact. | `ifc-mining-2007`; `epa-concrete-washout-2012` | ## 6.

Utilities and waste are stage-tagged once for their originating work; field readings remain process-specific. Complete subcontract services require overlap checks before separate material/fuel/plant inputs are added. Extend the map and atomic rows for every significant actual unlisted operation or stream before claiming dataset completeness. ### Process: Site definition and enabling works (`site_enabling`) Define the actual site/retained assets and perform the real survey, access, clearing, stripping and temporary arrangements; do not assume that every earthwork is needed. #### Inputs ##### Product flows ###### Uncontaminated natural soil fill (`imported_fill`) Only actual imported fill for integral access, collars or station foundations; retain soil class, moisture and compaction records.

Allocation and Co-product Handling | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | direct_subdivision | dataset | First trace each receipt, meter, machine log and work package to its actual facility and stage. Subdivide joint construction/ore production and adjacent power/manufacturing/building functions before allocation. For inseparable activities, justify an evidenced physical causal driver and complete beneficiary denominator using cp_allocation; cost, facility count or forecast throughput alone is not causal evidence. | | | asset_share_conservation | excavator_asset; drill_asset; crane_asset; formwork_plywood; steel_mesh | Retain one persistent identified asset and manufacture boundary. An actual same-configuration mass/count multiplied by its evidenced dimensionless current service share attributes the included manufacture burden. All projects, periods and repeated uses share one supported total-activity denominator; cumulative shares must not exceed one. Forecast versus realized service is explicit and reconciled. Unknown lifetime/activity remains review; never reset the full burden per project. Permanent new delivered support/equipment instead carries its included full supply burden once. | | | recovery_and_ore_interfaces | mine_excavation; construction_waste | Internal rock/fill/water reuse is an internal balance, not an automatic co-product credit. Exported ore, useful rock and scrap retain real status, quantities and recipients; no default avoided-production credit. Later mineral models consume the actual allocated construction dataset burden once rather than adding its ingredients/plant again. Shared downstream attribution requires actual supported production/service evidence, with unknown denominators disclosed for review. | | Direct attribution and cumulative-conservation controls are supported by the actual cp_assets/cp_allocation records; this PCR specifies no asset lifespan, mine output or allocation factor. Unproven relations remain explicit review needs for the actual dataset. ## 8.

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.

Permanent delivered material is its actual full included quantity once.

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.

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.
