Safety activity
MACHINERY · DAYS AWAY FROM WORK ONLY
Accident narrative
Miner was advancing shields when the pin on the relay bar broke and struck the miner in the ankle causing a small fracture.
HANDLING OF MATERIALS · NO DYS AWY FRM WRK,NO RSTR ACT
Accident narrative
A roof bolter operator was exposed to fluid when a hydraulic hose was inadvertently actuated and fluid sprayed from a cut in the hose into the employee's left eye. The employee immediately irrigated the affected eye but continued to experience irritation. EE was subsequently evaluated at a medical clinic, where a foreign object was removed from the eye and prescribed antibiotics.
HANDLING OF MATERIALS · DAYS AWAY FROM WORK ONLY
Accident narrative
The operator was performing a wash-down using hot condensate when the hose split, resulting in second-degree burns to the chest area.

Accident narrative
While lifting the longwall crusher into the cage using the overhead crane, the crane faulted. Had to get equipment to replace the fuse to continue loading and hoisting the crusher.
HANDLING OF MATERIALS · NO DYS AWY FRM WRK,NO RSTR ACT
Accident narrative
An employee was conducting an inspection of the burner in DR-8, Argo Kiln. The employee was wearing a Tyvek dust suit, N95 dust mask, gloves, a hard hat, and safety glasses.

An employee was standing on a 17 inch two step working platform performing maintenance work. As EE applied force to the box end wrench, the wrench slipped causing EE to lose balance and fall. In falling, EE's right knee contacted a ceramic liner, resulting in a fractured knee cap.
HANDTOOLS (NONPOWERED) · DAYS AWAY FROM WORK ONLY
Accident narrative
The employee was climbing down a scaffold ladder. Employee was tied off to an overhead SRL while descending a ladder. Their personal srl got caught on the scaffold gate. While descending the ladder, they noticed the caught psrl hook. As they looked up at it, the hook freed itself and retracted as designed. In that retracting process, the hook hit our employee in the mouth.
FALL OF ROOF OR BACK · DYS AWY FRM WRK & RESTRCTD ACT
Accident narrative
A Mine Production employee was in the process of bolting at 8 BMR. Employee noticed a bad top in the entry and exited the cab of the bolter to bar down the hazard. As employee barred down, the arch behind the employee came loose and fell and struck the employee from behind.
MACHINERY · NO DYS AWY FRM WRK,NO RSTR ACT
Accident narrative
A Mine Production employee was operating bolter drilling a 14 foot drill hole when the steel became stuck. EE placed EE's left hand on the drill steel to apply outward force to free the steel and reached for what EE thought was the lowering lever and inadvertently activated the rotation lever. In doing so EEs hand rotated with the drill steel causing a dislocated left pinky finger.
POWERED HAULAGE · DAYS RESTRICTED ACTIVITY ONLY
Accident narrative
The underground Utility Crew was taking structure down from a panel. As they were bringing in the forklift EE noticed a rail was close to the forklift tire and was going to run over it. EE bent down to move it out of the way, but the tire of the forklift ran over the end of the rail picking up the other side, hitting the employee in the lip.
SLIP OR FALL OF PERSON · DYS AWY FRM WRK & RESTRCTD ACT
Accident narrative
On February 11, 2025, a mine maintenance employee was performing routine maintenance on a borer miner. While stepping onto the bore miner rotor bit block, EE's foot slipped, resulting in a fall and a laceration to EE's left calf from contact with the borer miner bit. The injury required sutures.
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. 71 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.
