Celebrating 40 Years of Mine Safety and Health

The Federal Coal Mine Health and Safety Act of 1969
Public Law 91-173
91st Congress, S. 2917
December 30, 1969

On March 23, 2010 MSHA commemorated the 40th anniversary of the enactment of the Federal Coal Mine Health and Safety Act of 1969, known as the Coal Mine Act. This law profoundly changed mine safety and health in the United States.

The Coal Mine Act was born out of a terrible tragedy that took place on November 20, 1968 at Consolidation Coal's No. 9 mine in Farmington, WV. That tragedy, which took the lives of 78 miners,

The Coal Mine Act instituted the strongest and most comprehensive occupational safety and health protections that had ever been enacted in the U.S.

Throughout the years, mine safety and health have steadily improved in the United States. There are fewer fatalities, fewer injuries, fewer cases of occupational illness in the mines in this country today than there were in 1969. There has been steady, real, measurable progress.

We at MSHA celebrate the 40th anniversary of the Coal Mine Act - but we also take this anniversary as a call to do better, do more, to fulfill the promises made in the Act.

    On November 20, 1968, a massive explosion rocked the underground workings of Mountaineer Coal Co.'s Farmington No. 9 Mine in West Virginia. Of the 99 miners who were working in the mine at the time of the explosion, only 21 survived and escaped the mine. This group included eight who were rescued from the Mahan's Run air shaft. Nearly 40 years after the event, researchers from the NIOSH Pittsburgh Research Laboratory conducted oral history interviews with two of the eight survivors rescued from the shaft.
