An electromagnetic system for detecting and locating trapped miners
Filetype[PDF-651.57 KB]


Details:
  • Description:
    "The theory of electromagnetic fields indicates such fields could be used to detect and locate trapped miners. To be useful, the hardware of the system must meet a number of requirements, including small size, intrinsic safety, and rugged construction. Such hardware has been built, and the system has been tested by the Bureau of Mines and its contractors. These tests indicate that the electromagnetic method provides a practical means to locate miners in emergencies." - NIOSHTIC-2
