MSHA report : Damage inside the Farmington mine made it impossible for federal inspectors to complete their formal investigation of the disaster. But in March 1990 -- more than 21 years later -- the federal Mine Safety and Health Administration released an "informational report" on the explosion and fire.

Gazette investigative reporter Paul J. Nyden researched and wrote about the Farmington Disaster when he was working on a dissertation about the rank-and-file reform movement in the United Mine Workers union. Nyden completed his dissertation, "Miners for Democracy: Struggle in the Coalfields," in 1974, and received a Ph.D. from Columbia University. Nyden has been covering coal industry issues for the Gazette for more than 26 years. The following links are excerpts from his dissertation relating to the tragedy.
