10/1/2011 - Technology NewsThis 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.
-
9/1/2011 - Technology NewsPossible 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.
-
1/1/2010 - Conference papersThis paper describes two algorithms that can provide greater accuracy for underground miner tracking systems.
-
1/1/2010 - Conference papersThis paper introduces algorithms to locate miners with no need for external reference sensors. There are definitions of useful mathematical operations that can be performed on the node coordinates and includes a description of the algorithms.
-
1/1/2009 - Conference papersThis paper introduces two position adjustment methods for mine tracking systems which use a coplanar node-path network mine model as the foundation for their development.

7/1/1985 - Open File ReportsEfforts to produce electromagnetic systems for the location of trapped miners underground and to communicate with them were surveyed, from the 1920s to 1981. Theoretical studies of through-the-earth electromagnetic transmissions are described as well as...
-
1/1/1984 - Reports of InvestigationsA short-range locator system capable of locating trapped miners has been devised. The system consists of a light-weight, low-power radio transmitter incorporated into a miners cap lamp battery and a directional receiver carried by rescuers.
-
1/1/1983 - Reports of InvestigationsAn essential element of the USBM electromagnetic location and communication system for trapped miners is knowledge of the surface and above-surface electromagnetic fields created by an underground transmitter.
-
1/1/1976 - Reports of InvestigationsThe 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. S...
