    Accident narrative

    Schindler changed out the four roller guide assemblies on the Miracle Run elevator, upon returning to service after the install there was enough side movement for the safety dogs to grab and set, resulting in an entrapment of 3 miners at the top of the shaft for approximately 35 minutes until the safety dogs could be reset.

Sources and definitions

MSHA Violations (issue date), Accidents (accident date) and Inspections (begin date).

Violation titles use current CFR headings to identify the cited rule; they are not the inspector’s account of what happened.

Status is from the current MSHA Mines snapshot, not the selected reporting period. Closed records can retain their last reported controller/operator.

Counts describe published rows, including contractor records; accident records are not distinct incidents or numbers of people injured.

Zero means no matching records in the imported sources, not proof of no events. Historical coverage differs by source; absence before a source begins reporting is not a zero incident rate. Invalid or absent dates and records after the snapshot are excluded.

S&S means SIG_SUB=Y. Fatality records use DEGREE_INJURY_CD=01. Proposed penalties are not final assessed or paid amounts; missing dollar values are omitted.

Inspection hours are SUM_TOTAL_ON_SITE_HOURS attributed to the inspection start date, without supervisor/trainee hours. Missing hours are omitted; a started inspection may still be open.

Portfolio totals use current mine membership, including events before the current owner or operator's tenure.
