Accident narrative
EE was assisting with final seal prep cleaning the bottom with a shovel when a piece of rock fell from the top and struck their hand against the shovel handle, causing a laceration. Injury was not the result of a training or compliance issue. 7000-1 was initially filled out 5/12/25, but the "Submit" button was inadvertently not clicked, thus this late submission.

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.
