• Comparison of the Transverse Load Capacities of Various Block Ventilation Stoppings under Arch Loading Conditions
  6/1/2008 - Conference papers
  This paper compares the transverse load capabilities of several block materials and wall dimensions commonly used in stopping constructions based upon simulated three-hinge, rigid-arch loading tests of half-wall constructions.
• Empirical Approaches for Opening Design in Weak Rock Masses
  3/1/2005 - Peer reviewed journal articles
  A major focus of ground control research presently being conducted by the Spokane Research Laboratory of the National Institute for Occupational Safety and Health (NIOSH) is to incorporate weak rock masses (such as are associated with operations in the ...
• Design in Weak Rock Masses: Nevada Underground Mining Operations
  2/1/2005 - Conference papers
  One focus of ground control research at NIOSH is to incorporate data on weak rock masses into existing design relationships, with an emphasis on updating the span design curve for manned entries and the overbreak curve for longhole entries. Both curves ...
• Preventing Injuries Caused by Unrecognized Stone Mine Roof Beam Failures With a Pro-Active Roof Control Plan
  3/1/1999 - Conference papers
  To help mitigate the potential for falls-of-ground injuries to underground stone miners, NIOSH developed the Roof Monitoring Safety System (RMSS) to aid in monitoring dangerous levels of roof beam deflection.
