Accident narrative
Employee injured left ankle while clearer brush at the 006-discharge pond. EE states took a step on an incline, slipped and fell followed by pain in ankle. EE also said a popping sound was heard.

FIRE · ACCIDENT ONLY
Accident narrative
On 3/10/2026 6:30 p.m. management was made aware that the surface trash compactor storage container had material inside on fire. This metal container measures eight feet by 22 feet and is used to transport trash from the mine property to an offsite dump. MSHA was notified and the fire was extinguished. There was no damage to property or injury due to this incident.
HOISTING · ACCIDENT ONLY
Accident narrative
On 3/6/2026 3:20 a.m. management was made aware power had been lost to the slope hoist. This being the secondary escapeway, all mine personnel were evacuated using the primary escapeway. MSHA was notified when power restored at 4:02 a.m. No miners were injured due to this incident.
SLIP OR FALL OF PERSON · DYS AWY FRM WRK & RESTRCTD ACT
Accident narrative
The EE walked to a roadside berm that had 2 feet wide opening to allow water to exit the roadway into a ditch. While standing at this opening, the ice underneath EE broke, causing EE to lose EE's balance. EE then slid down the ditch wall 4 feet before EE's left foot contacted a tree branch. This contact resulted in a dislocated and fractured ankle.
HANDTOOLS (NONPOWERED) · DAYS RESTRICTED ACTIVITY ONLY
Accident narrative
On 2/4/2026 an employee was using a spud bar to clean material from a clogged chute at the surface crusher when EE injured EE's right pinky finger. EE refused treatment at time of incident, but after seeing a doctor on 2/26 & 2/27 it was determined EE's finger had been fractured.

HOISTING · ACCIDENT ONLY
Accident narrative
On 12/18/2025 the vertical shaft hoist (primary escapeway) was taken out of service due to not being able to close the surface landing door. No miners were in the mine when this issue was found. It was determined a bolt on the landing door track needed replaced.
HOISTING · ACCIDENT ONLY
Accident narrative
On 12/1/2025 MSHA was notified that the vertical shaft hoist was being taken out of service due to intermittent issues. The brake alarm was resolved after adjustment per manufacturer specification. There was also a problem with a control wire, which was changed out with a spare. No miners were injured due to this incident.
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. 46 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 + TITLE 30
EIA production and cited regulations
EIA annual figures are reported separately from MSHA. Regulation links use the current eCFR snapshot.
This can mean the operation is non-coal, inactive for the annual period, or outside the EIA-7A reporting population.

Limitations
- Contractor production is entity-level and is never represented as mine-attributable.
- Missing rows can mean no event, publication delay, identity mismatch, or inapplicability.
