Avísenme cuando se presente un nuevo incidente de la MSHA en cualquier mina de Birchfield Mining Inc.
VICTIM WAS FOUND UNDER A SECTION OF FALLEN DRAW ROCK IN THE NO. 6 ENTRY ON THE OFF-SIDE OF THE CONTIONUS MINER ABOUT 2 FEET OUT FROM UNER SUPORRTED TOP. INTERVEIWS WERE HELD WITH PERSONS WHO FOUND AND RECOVERED THE VICTIM, BUT IT COULD NOT BE DETERMINED THE REASON FOR TRAVELING BEYOND THE LAST ROW OF BOLTS.
MSHA's standard limits respirable silica to 50 micrograms per cubic metre, but MSHA publishes dust and quartz as separate files and never the silica figure itself. We derive it per sample, score it against the limit, and set the operator's injury rate against a benchmark built from the full MSHA operator record. With the 26-year penalty trail, contest posture, and fatality history. Delivered as a PDF with the underlying data as CSV.
The federal record itself stays free on this site. What costs money, and why.
