HOISTING · ACCIDENT ONLY
Accident narrative
Silver Shaft hoist operator heard noise coming from the drum while the hoist was in operation. The hoist operator called maintenance to come inspect the hoist and they found that a saddle and both nuts on a Crosby clamp had come loose. The clamp that came loose was one of 4 extra clamps that were added to hold the tail of the rope on the inside of the drum.

Spot Inspection · 3.8 on-site hours
HOISTING · ACCIDENT ONLY
Accident narrative
The hoist tripped due to the gap on the right brake stand-2 upper caliper was detected on the hoist control system to be outside of tolerance at 2mm. The gap was checked and adjusted to 0mm at which time the hoist was reset and back operational. The Silver Shaft Hoist (primary) and 2 Shaft hoist (secondary) were operational throughout.

HOISTING · ACCIDENT ONLY
Accident narrative
Lost incoming power to the mine site for a short period of time due to a weather event which caused the hoists to trip. The hoists and compressors needed to be reset and started back up. Hoists were back operational by 7:04 PM.
POWERED HAULAGE · DAYS AWAY FROM WORK ONLY
Accident narrative
Employee was transporting a tote of diesel fuel and got a flat tire on the 1-yard forklift they was using to transport the fuel. Employee was pulling into a cutout to get it out of the roadway and as they were pulling in they hit a bump and reached their arm out toward the rib and strained left shoulder. Employee ended up having to get surgery for a rotator cuff injury.

FIRE · ACCIDENT ONLY
Accident narrative
Miner was mucking into a muck bay with a 2-Yard LHD. They had a full bucket and when attempting to dump it they got on uneven ground and as they raised the bucket the loader tipped over onto the right side. After it tipped, oil and fuel began to leak onto hot components of the exhaust and possibly the turbo which caused the fluids to ignite, resulting in the loader catching fire.

Accident narrative
EE was moving a jumbo drill steel and pinched left ring finger between the steel and the metal box on the loader fender.

Safety sources and definitions
MSHA Violations (issue date), Accidents (accident date), and Inspections (begin date). Snapshot 2026-10-18.
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 18, 2026. 23 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.

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.
