Safety activity
Spot Inspection · 4.0 on-site hours
POWERED HAULAGE · NO DYS AWY FRM WRK,NO RSTR ACT
Accident narrative
The employee was spotting empty barges forward when a wire rope became caught on the wrong side of a kevel. While attempting to reposition the wire rope, the rope under tension struck the employee in the ankle, causing the employee to fall to the deck.
HANDLING OF MATERIALS · DAYS AWAY FROM WORK ONLY
Accident narrative
The employee was using a dial indicator to check runout on a motor sheave. After positioning the dial indicator, the employee manually pulled on the belts to rotate the sheave. During this process, the employee's finger became caught between the belt and sheave.

POWERED HAULAGE · DAYS RESTRICTED ACTIVITY ONLY
Accident narrative
The employee identified a material blockage in a rotary feeder and attempted to clear the obstruction using an air lance. While maneuvering the air lance inside the chute, the running rotary feeder pulled the air lance and the employee's hand toward the feeder. The employee's hand became caught resulting in a laceration. No LOTOTO was applied.

Safety sources and definitions
MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-17.
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.
CFR headings link to the current Title 30 index; they are not historical legal determinations.
OWNERSHIP
Operator and controller history
Current ownership comes from MSHA Mines. Historical start and end dates come from MSHA Controller and Operator History.

Silica and quartz
Coal quartz, metal/nonmetal personal samples and area samples. Snapshot Oct 17, 2026. 7 silica records across the mine’s published history.
Personal silica samples · concentration / limit
Quarterly mean · published C/E ratio
— No eligible measurements. * Quarter in progress. Means describe the available samples, not average exposure across the mine.
Quartz % is the sample’s quartz content; µg/m³ is its reported concentration. Personal C/E is the ratio to the limit published with that sample. Personal and area concentration units and void status are not specified in those source files.

Sources and interpretation
- Coal means use numeric concentrations from samples marked not voided, excluding control/invalid sample types and dates after the snapshot. Missing values remain null; reported zeroes remain zero.
- Quarterly means describe available samples, not mine-wide or worker-average exposure. Quarters with no eligible measurements remain empty; the current quarter is partial.
- Personal C/E is MSHA's published concentration-to-limit ratio. A value above 1 is not by itself a citation or a determination under the 2024 silica rule. Personal and area files do not publish a void-status field.
- Area records include bulk-dust analyses and are kept separate from personal exposure results. Their concentration units are not specified in the source dictionary.
- Missing samples do not establish safe conditions. Coal quartz percentage and concentration are separate measures. No compliance threshold is inferred for coal samples.
