Results Of In Mine Research In Support Of The Investigation Of The Sago Mine Explosion

At the request of the Mine safety and Health Administration (MSHA) and the West Virginia Office of Miners' Health, Safety, and Training, the NIOSH's Pittsburgh Research Laboratory evaluated the effects of explosions on specific mine ventilation seals at its Lake Lynn Experimental Mine to assist the agencies in their investigations of the explosion at the Sago Mine in West Virginia, which occurred on January 2, 2006. Six full-scale explosion tests were conducted to help answer questions regarding possible scenarios for the Sago explosion. NIOSH's findings and recommendations are documented within.

"The Mine Safety and Health Administration (MSHA) and the West Virginia Office of Miners' Health, Safety, and Training (WVOMHS&T) investigated the explosion at the Sago Mine in West Virginia, which occurred on January 2, 2006, and resulted in 12 fatalities. As part of the investigation, the agencies requested that the National Institute for Occupational Safety and Health's (NIOSH) Pittsburgh Research Laboratory evaluate the effects of explosions on specific mine ventilation seals and other structures and objects at its Lake Lynn Experimental Mine (LLEM). The results of the LLEM study would assist MSHA and WVOMHS&T in a more thorough understanding of the various questions that arose during their investigations of the explosion. Six large-scale explosion tests were conducted in the LLEM from April to October 2006. The protocols for these tests, and in particular the procedures for constructing various Omega block seals, were developed mainly by MSHA and WVOMHS&T. NIOSH developed the experimental procedures at the LLEM that would provide the required range of explosion pressures against the seals ... By comparing the results of known explosion loading pressures on the various ventilation structures and objects in the LLEM with their observations at the Sago Mine, MSHA and WVOMHS&T could better analyze the explosion pressures that may have occurred at the Sago Mine."--P.

The U.S. mining sector has the highest fatality rate of any industry in the country. Fortunately, advances made over the past three decades in mining technology, equipment, processes, procedures, and workforce education and training have significantly improved safety and health. The National Institute for Occupational Safety and Health (NIOSH) Mining Safety and Health Research Program (Mining Program) has played a large role in these improvements. An assessment of the relevance and impact of NIOSH Mining Program research by a National Research Council committee reveals that the program makes essential contributions to the enhancement of health and safety in the mining industry. To further increase its effectiveness, the Mining Program should proactively identify workplace hazards and establish more challenging and innovative goals toward hazard reduction. The ability of the program to successfully expand its activities, however, depends on available funding.

These research papers also cover a spectrum of innovative technical solutions, including computer-controlled mining equipment, remote monitoring of air quality, and virtual reality training systems.
