• Description:
  In 2008, the Mine Safety and Health Administration (MSHA) mandated refuge alternatives (RAs) in underground coal mines. For RAs, federal regulations specify a design pressure of 103.4 kPa (15 psi). This paper discusses the blast response of built-in-place RA doors. Researchers at the National Institute for Occupational Safety and Health (NIOSH) performed linear static finite element (FE) analyses on a built-in-place (BIP) RA door using two loading conditions: a 103.4-kPa (15-psi) design pressure and a 20.7-kPa (3-psi) negative pressure. Both of the FE analyses showed that the door yielded. The information presented in this paper can be used to ensure that BIP RA stoppings and doors can withstand survivable explosions.
