• Comparison of Ore Pass Computer Simulations for Designs Against Dynamic Load
  2/1/2003 - Conference papers
  In this paper, existing ore pass design criteria rules-of-thumb using current particle flow equations are reviewed and a comparison of two computer modeling programs, Working Model (WM 2-D) and PFC2d, to simulate rock flow are investigated.
• Technology News 479 - Ore Pass Level and Blockage Locator Device
  1/1/2000 - Technology News
  Bridging of material in ore passes causes blockages in the flow of material. These blockages can be hazardous and must be removed before production can continue.
• Static and Dynamic Loads in Ore and Waste Rock Passes in Underground Mines
  6/1/1999 - Conference papers
  This paper describes research to improve safety during transport of ore and waste in underground mines.
• Safety Considerations for Transport of Ore and Waste in Underground Ore Passes
  3/1/1999 - Peer reviewed journal articles
  NIOSH researchers are investigating methods to improve safety during the transport of ore in ore passes.
• Design Analysis of Underground Mine Ore Passes: Current Research Approaches
  5/1/1998 - Conference papers
  The U.S. Mine Safety and Health Administration (MSHA) has identified ore pass hazards as s significant safety problem in underground metal mines in the United States. Researchers at the Spokane Research Laboratory of the National Institute for Occupati...
• Technology News 470 - Analysis of Hangups and Structural Failure in Underground Mine Ore Passes
  2/1/1998 - Technology News
  Recent ore pass failures have underlined the lack of ore pass design methods and standards available to both MSHA and mine engineers.
• Technology News 458 - Development of a Research Facility to Improve Mine Hoisting and Ore Pass Safety
  5/1/1997 - Technology News
  The Mine Safety and Health Administration (MSHA) has requested new safeguards and design criteria for hoists and ore passes. However, equipment suppliers and mining companies cannot justify the costs nor interrupt production to develop and test safer te...
