AGENCY:

National Institute for Occupational Safety and Health (NIOSH), Department of Health and Human Services (HHS).

SUMMARY:

The National Institute for Occupational Safety and Health (NIOSH) announces the following availability of opportunity for the public to provide input regarding the draft document, “Explosion Pressure Design Criteria for New Seals in U.S. Mines.”

NIOSH is the Federal agency responsible for conducting research and making recommendations for the prevention of occupational injuries and illnesses, including those occurring in the mining industry. Federal Mine Safety and Health Act, 30 U.S.C. 951.

Seals are dam-like structures constructed in underground coal mines throughout the U.S. to isolate abandoned mining panels or groups of panels from the active workings. Historically, mining regulations required seals to withstand a 140 kPa (20 psi) explosion pressure; however, the 2006 MINER Act requires MSHA to increase this design standard by the end of 2007. This report provides a sound scientific and engineering justification to recommend a three-tiered explosion pressure design criteria for new seals in coal mines in response to the MINER Act. Much of the information contained in this report also applies to existing seals.
