global coal mines (~5.4k non-closed) with capacity/production/reserves, coal grade + met%, owners, lat/long; strata ingests the metallurgical (coking) slice only

Quirks

metallurgical-coal slice only - fills strata's sole Tier-2b scope-exclusion gap (USGS tracks no met coal); thermal coal out of scope
met-attributable tonnage = raw × met fraction (explicit Percentage of Met Coal, else 1.0 for pure 'Met' grade, else 0.0); only operating mines counted
country-aggregated SupplyRecord (capacity/production/reserves) plus a mine-level DepositOccurrence lane (met-attributable mines, keyed on capacity - Chinese mines publish capacity but no production)
values in million metric tons (Mt/Mtpa) per the source - NOT thousand-tonne USGS convention

Cache-only; operator drops the vendored XLSX into data/raw/gem_coal_mines/<vintage>/
