Esta tasa son las citaciones registradas divididas entre las horas de inspección de la MSHA, por cada 100 horas. Refleja el esfuerzo de inspección, no el tamaño de la mina ni la producción.ⓘ
Una orden bajo la Sección 107(a) retira a los mineros de un área cuando un inspector detecta un peligro inminente. Cada orden se levanta una vez corregida la condición, por lo que esto cuenta las órdenes emitidas, no las que están en vigor ahora.Fort Calhoun Underground Mine tiene $142K en multas propuestas de MSHA y $1K pendientes en 7 expedientes impugnados.
ⓘ
Las diferencias entre las multas propuestas y las pagadas reflejan tanto acuerdos y reducciones en conferencia como montos aun adeudados. Pendiente es el saldo que se debe actualmente.ⓘ
Las proporciones se calculan sobre las citaciones que llevan la codificación de gravedad y negligencia de la MSHA; una pequeña parte de los registros no está codificada.ⓘ
Impugnar una citación ante la Comisión Federal de Revisión de Seguridad y Salud Minera es un derecho legal. Estas cifras presentan los resultados públicos de ese proceso, según el archivo de Violaciones Impugnadas de MSHA.- Conciliadas 10 · 83%
- Anuladas o retiradas 2 · 17%
ⓘ
Una citación Significativa y Sustancial cuenta como sobreviviente cuando la conciliación o la decisión del juez mantuvo la designación, o cuando la impugnación fue desestimada o quedó en rebeldía y la citación quedó como emitida. Las citaciones anuladas o retiradas, y las conciliaciones que quitaron la designación, cuentan en contra.ⓘ

Fort Calhoun Underground Mine registró 2.09 casos de lesión reportables por cada 100 trabajadores a tiempo completo en 2025.
ⓘ
Esta tasa son los casos de lesión reportables por cada 100 trabajadores a tiempo completo por año, calculada como 200,000 por los casos dividido entre las horas-empleado reportadas por el operador a la MSHA. Los casos son lesiones que la MSHA clasificó en grado 01 a 07; se excluyen los eventos de solo accidente que no lesionaron a nadie, y también las lesiones de contratistas, cuyas horas no corresponden a una sola mina. Las tasas comienzan en el año 2000, cuando inicia el reporte trimestral de empleo, y se omiten por debajo de 20,000 horas en un año.| Año | tasa de casos totales | días perdidos | mortales |

Fort Calhoun Underground Mine se ubica en Washington County, Nebraska, donde la categoría minera del Censo representa el 0.4% del empleo del condado.
ⓘ
Las cifras del condado provienen de la Encuesta sobre la Comunidad Estadounidense de la Oficina del Censo de EE. UU., estimaciones quinquenales agrupadas, por lo que la edición de 2023 abarca de 2019 a 2023. La categoría del Censo es 'minería, explotación de canteras y extracción de petróleo y gas', que es más amplia que la jurisdicción de la MSHA e incluye a trabajadores de petróleo y gas que ninguna mina emplea. Estas cifras describen el condado circundante, no esta mina, y no son un factor en ningún incidente específico.ⓘ
