• 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 544 - New Measurement Tool to Validate Wireless Communications and Tracking Radio Signal Coverage in Mines
  10/1/2011 - Technology News
  This technology is used to map communications and tracking coverage in underground mines. It is important to know coverage of these systems during a mine emergency.
• 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.
