• Optimizing Secondary Roof Support with the NIOSH Support Technology Optimization Program (STOP)
  8/1/2000 - Conference papers
  The 1990s saw an unprecedented increase in technologies for more effective, easier to install roof support in underground mines. To facilitate application and improve mine safety, NIOSH developed the Support Technology Optimization Program (STOP).
• Economics of Safety at Surface Mine Spoil Piles
  7/1/2000 - Reports of Investigations
  Short-dumping rather than edge-dumping might reduce dumping-related accidents, but many operators believe it is less cost effective. To evaluate this perception, NIOSH reviewed the costs of various dumping methods at waste and spoil piles.
• Ignition of Methane-Air Mixtures by Laser Heated Small Particles
  5/1/2000 - Peer reviewed journal articles
  Optical technologies have progressed rapidly in the past 15 years. NIOSH is conducting a study to help provide a scientific basis for developing appropriate safety guidelines for optical equipment in underground coal mines.
• Application of the Coal Mine Roof Rating (CMRR) to Extended Cuts
  4/1/1999 - Peer reviewed journal articles
  The Coal Mine Roof Rating (CMRR) has been widely accepted as a tool for geologic characterization and mine planning. The application of the CMRR to extended cuts (cuts greater that 6 m (20 ft) in length) is discussed.
• Laser Ignition of Flammable Gas
  3/1/1999 - Conference papers
  Emerging laser technologies are quickly gaining acceptance in the industrial workplace. This NIOSH research provides a scientific basis for developing safety guidelines for optical equipment in the presence of flammable methane gas and coal dust.
• Technology News 455 - Roof Hazard Alert Modules
  5/1/1997 - Technology News
  The new permissible-type, intrinsically safe design modules described here represent an engineering intervention strategy toward improving miners' ability to recognize and avoid the hazardous zone of unsupported mine roof.
• Coal Dust Explosibility
  1/1/1996 - Peer reviewed journal articles
  This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal.
• Methods to Mitigate Fire and Explosion Hazards of Lithium-ion Batteries
  12/29/2023 - Research projects
  A pilot project to address unresolved questions in the mining industry about the potential for pressurized explosions within explosion-proof enclosures containing lithium-ion batteries.
• Characterizing the Generation and Mitigation of Hazardous Gases during Lithium-ion Battery Failure Events
  11/21/2023 - Research projects
  A project to characterize gas generation from lithium-ion batteries used in battery electric vehicles during a battery failure event and identify mitigation strategies that can reduce gas hazards and protect U.S. mineworkers.
• Managing Ground Support for Long-Term Stability in Underground Mines
  5/2/2023 - Research projects
  A project to elucidate effective ground control management strategies and develop tools that help to forecast time-dependent processes in relation to rate or possible outcome.
