FIRE · ACCIDENT ONLY
Accident narrative
An 8-inch HDPE water-cooling pipe ignited after being placed on hot reactive rock. The Fire Team was dispatched at 9:51 p.m., arrived at 9:58 p.m., and extinguished the fire at 10:18 p.m. No personnel were in the vicinity, and no injuries or exposures were reported. Time of initial fire discovery: pending verification.
Impoundment Spot Inspection · 6.0 on-site hours
POWERED HAULAGE · DAYS AWAY FROM WORK ONLY
Accident narrative
Employee was assisting with a Vac-Truck hose in deep, muddy tundra conditions when unstable footing restricted movement and body positioning. While applying force to control the hose, their grip slipped and the hose contacted their right shoulder. Injury resulted in right anterior shoulder dislocation, restricted work duty.
SLIP OR FALL OF PERSON · DAYS AWAY FROM WORK ONLY
Accident narrative
777-Operator was dismounting a parked truck, misjudged the distance to the ground, rolled and twisted ankle upon impact and fractured lower leg bones.
HANDLING OF MATERIALS · NO DYS AWY FRM WRK,NO RSTR ACT
Accident narrative
EE was in the rigging connex retrieving a chain hoist. When they picked it up, it pulled another chain that was under their left foot. This caused the ankle to roll resulting in a fracture to the 5th metatarsal.
Impoundment Spot Inspection · 15.0 on-site hours
SLIP OR FALL OF PERSON · DAYS AWAY FROM WORK ONLY
Accident narrative
An employee was moving a 4D battery off a drill. The employee placed the battery on the left side guardrail of the platform. The battery became unstable and slipped off the guardrail. While attempting to follow or catch the battery, the employee fell to the floor, landing on their left palm. The employee reported a dislocated left shoulder

Safety sources and definitions
MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-13.
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 13, 2026. 25 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.
| Date / sample | Dataset / analyte | Occupation / area | Measurement | Sample status | Published action |
|---|---|---|---|---|---|
| No silica records match these filters. Missing samples do not establish safe conditions. | |||||
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.

EIA production and cited regulations
EIA annual figures are reported separately from MSHA. Regulation links use the current eCFR snapshot.
Not present in the 2024 EIA coal workbook.
This can mean the operation is non-coal, inactive for the annual period, or outside the EIA-7A reporting population.
