• Two-Way, Through-the-Earth Emergency Communication System for Trapped Miners and the Surface
  9/18/2012 - Contracts and cooperative agreements
  A contract to design a prototype two-way, through-the-earth (TTE) emergency communication system, fabricate the hardware, and test the system at an underground coal mine.
• Performance and Safety Investigation of Emergency Backup Batteries and Battery Charging Systems for Underground Mining Applications
  9/18/2012 - Contracts and cooperative agreements
  A contract to address issues associated with battery selection, use, and charging for the underground coal mining environment, specifically with respect to MINER Act requirements for mine communications and personnel tracking technology.
• Passive Fiber Optic System for Locating, Tracking, and Communicating with Personnel in Coal Mines
  9/17/2012 - Contracts and cooperative agreements
  A contract to develop and demonstrate a modified, fiber optic-based perimeter security system to track personnel in an underground coal mine.
• Technology News 547 - Cost-Effective, Off-the-Shelf Wireless Links for Surface Integrated Mine Emergency Communications
  12/1/2011 - Technology News
  A surface network system using off-the-shelf components successfully established strategic communications links in a limited mine-simulated environment. The system could be expanded to link other communication devices and a command center.
• Training for Safety in Emergencies Inoculating for Underground Coal Mine Emergencies
  11/1/2011 - Peer reviewed journal articles
  Emergency training for miners can use inoculation theory, which explains how people can resist persuasion attempts by preparing counterarguments in advance. The theory may be used to prepare workers to react quickly by preparing responses in advance.
• Nonverbal Communication for Mine Emergencies
  11/1/2011 - Reports of Investigations, Training materials
  Nonverbal Communication for Mine Emergencies is a training program that teaches miners a series of nonverbal hand signals to use in the event of an emergency. These hand signals can be used by miners if they are unable to communicate verbally.
• Technology News 543 - Reverse Implementation of Radio Frequency Identification (RFID) Technology for Personnel Tracking in Underground Mines
  9/1/2011 - Technology News
  Possible benefits of the use of reverse RFID for personnel tracking are: improvements in accuracy, the ability to interface to a variety of mine communications infrastructures, better system survivability, and easier installation and maintenance.
• Radio 101: Operating Two-Way Radios Every Day and in Emergencies
  8/1/2011 - Reports of Investigations, Training materials
  Radio 101 is a program to train miners in the use of two-way radio communication in the mines.
• MultiFit4: An Improved System for Insert-Type
  9/1/2010 - Peer reviewed journal articles
  This paper describes the results of initial testing of the NIOSH Multifit4 system that was designed to be used as a tool by qualified researchers to evaluate hearing protector training and fit interventions at worksites.
• Acoustic Assessment of Pneumatic and Electric Jackleg Drills used in the Mining Industry
  4/1/2010 - Conference papers
  This paper presents an acoustic assessment of pneumatic and electric jackleg drills involving Noise Source Identification (NSID), penetration rate measurements, operator’s cumulative noise dose measurements, and determination of sound power levels.
