At approximately 5:30 a.m. on Wednesday, November 20, 1968, an explosion occurred in the Consol No.9 Mine, Mountaineer Coal Company, Division of Consolidation Coal Company, Farmington, Marion County, West Virginia. There were 99 miners in the mine when the explosion occurred, 78 of whom died as a result of the explosion. The other 21 miners survived the explosion and escaped to the surface. The mine was sealed at its surface openings on November 30, 1968. Damage to the mine in the explosion area was extensive, requiring loading of rock falls, replacement of ventilation and transportation facilities, and in some cases new mine entries to bypass extensively caved areas. Investigative activities were continued, in cooperation with the Company, State, and United Mine Workers of America (UMW A) organizations, as mine areas were recovered. Between 1969 and 1978, the bodies of 59 victims were recovered and brought to the surface. Recovery operations ceased and all entrances to the mine were permanently sealed in November 1978, leaving 19 victims buried in the mine and leaving some areas of the mine unexplored. Lessons learned during early evaluation of this disaster were incorporated into the Federal Coal Mine Safety and Health Act of 1969. The Federal Coal Mine Health and Safety Act of 1969, generally referred to as the Coal Act, was more comprehensive and more stringent than any previous Federal legislation governing the mining industry. The Coal Act included surface as well as underground coal mines within its scope, required two annual inspections of every surface coal mine and four at every underground coal mine, and dramatically increased federal enforcement powers in coal mines. The Coal Act also required monetary penalties for all violations, and established criminal penalties for knowing and willful violations. The safety standards for all coal mines were strengthened, and health standards were adopted. The Coal Act included specific procedures for the development of improved mandatory health and safety standards, and provided compensation for miners who were totally and permanently disabled by the progressive respiratory disease caused by the inhalation of fine coal dust pneumoconiosis or "black lung".
