• Mine Roof Simulator (MRS) Laboratory
  10/22/2016 - Research projects
  A project to utilize the capabilities of the Mine Roof Simulator (MRS) Laboratory to test underground roof support and ventilation structures and apply these results to engineer safer products and applications.
• Improved Dust Control Methods for Longwall Mining
  10/22/2016 - Research projects
  A project to develop control technologies that will reduce the most common sources of respirable dust on the longwall face, which will in turn protect the health of mine workers on the longwall face.
• Brody Mine Accident Highlights Need for Retreat Mining Safety
  10/22/2016 - News articles
  A short feature story describing NIOSH products on retreat mining.
• Empirical Guidelines for Longwall Ground Control Design
  10/22/2016 - Research projects
  A project to update the database of case histories upon which the Analysis of Longwall Pillar Stability (ALPS) software bases its recommended stability factors.
• Calibration and Verification of Longwall Stress Models
  10/22/2016 - Research projects
  A project to address the paucity of guidance in available literature for assessing the design an underground longwall coal mine for safe ground response to mining with numerical stress analysis tools.
• Modeling Natural Gas Explosions for Coal Mine Safety
  7/19/2016 - Contracts and cooperative agreements
  A contract to simulate the development and evolution of natural gas (NG) explosions in mine tunnels.
• Medium Frequency Radio System Modifications for Refuge Chamber Situational Awareness
  7/19/2016 - Contracts and cooperative agreements
  A contract to modify medium frequency radio systems to improve refuge chamber situational awareness in an underground coal mine.
• Leaky Feeder to Wireless Media Converter Device Technology Development
  7/19/2016 - Contracts and cooperative agreements
  A contract to develop and test a Media Converter Device (MCD) that allows wireless handheld radios to communicate with leaky feeder communication systems. This will greatly improve voice quality and underground communications coverage in cross-cuts.
