Organisation-associated mine operating and hazard profile

For mines associated through current operator or controller identifiers, the nationwide MSHA full file reports Mine ID, name, type, and location; current status and status date; days per week, hours per shift, and production and maintenance shifts; average mine height; mine-gas category and methane liberation; producing and nonproducing pit counts, multiple-pit and tailing-pond indicators; pillar-recovery and highwall-miner use; portable-operation status; and miners’ representative and safety-committee indicators. It is primary governmental evidence for the mine-specific operating and physical-hazard profile, subject to field applicability, commodity-specific definitions, null values, retrieval-date pinning, and the rule that controller attribution does not prove ownership.
