Órdenes por peligro inminente
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.

Cuando se impugnaron las citaciones
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.

La designación S&S sobrevivió la impugnación
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.

El muestreo de MSHA en Black Thunder muestra que 98% de 1,342 muestras de polvo respirable de carbón cumplieron el estandar de 1.5 mg/m3.

Muestreo de salud
Una muestra es una medición de cumplimiento en un momento dado, no un historial de exposición individual. Estas cifras describen registros de muestreo de MSHA y no establecen causalidad ni dosis personal.

Polvo respirable de carbón
Las cifras de polvo respirable de carbón y sílice corresponden a instalaciones de carbón. El cumplimiento del polvo se mide frente a la norma actual de 1.5 mg/m3; se incluyen muestras anteriores a la norma de 2014, por lo que las tasas de cumplimiento son una senal historica aproximada.

sobre el ECV de MSHA
El valor de concentración excesiva (ECV) es el umbral de aplicación por muestra de la propia MSHA, que incorpora la incertidumbre de medición; una muestra por encima de su ECV puede motivar una citación. El conteo cubre solo las muestras a las que MSHA asignó un ECV.
626 muestras tomadas por inspectores de MSHA, 716 por el operador.

Black Thunder registró 0.47 casos de lesión reportables por cada 100 trabajadores a tiempo completo en 2025.

Tasa de lesiones, 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.

Black Thunder se ubica en Campbell County, Wyoming, donde la categoría minera del Censo representa el 17.6% del empleo del condado.

Contexto económico local
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.

Tasas de seguridad trimestrales
Citaciones por millón de horas-empleado reportadas. Las tasas comienzan en el año 2000, cuando inician los datos trimestrales de empleo de la MSHA; los incidentes anteriores se cuentan pero no pueden ajustarse por tasa. Los trimestres con menos de 100,000 horas reportadas se muestran en gris: muy pocas horas para una tasa estable.
