This tutorial provides an advanced discussion of the available CT technologies, operating characteristics and general system performance considerations with descriptions of specific uses for primary and secondary communications.
2/1/2012 - Technology NewsMedium frequency communications systems do not require a powered underground infrastructure to be installed for operation, and may therefore provide a higher degree of survivability after a mine disaster than other types of systems.
3/1/1975 - Peer reviewed journal articlesThe theoretical study of UHF radio communication in coal mines, with particular reference to the rate of loss of signal strength along a tunnel, and from one tunnel to another around a corner is the concern of this paper. This work was part of an invest...
