8/1/2005 - Conference papersThe objective of this work was to determine if GPR could be used to help assess the mine roof conditions near the No. 4 Portal area of the NIOSH Lake Lynn Experimental Mine (LLEM).
-
3/1/2005 - Conference papersNIOSH used ground-penetrating radar (GPR) technology to determine if each of three test mine seals were uniformly constructed. The results suggest that GPR could be used as a tool to evaluate mine seal characteristics and construction uniformity.
-
8/1/2004 - Conference papersThe study tested ground penetrating radar's ability to determine the extent of grout penetration into mine roof strata in the NIOSH Safety Research Coal Mine. The study showed that GPR technology can be useful in detecting roof changes due to grout.

9/1/1996 - Conference papersThe U.S. Department of Energy Pittsburgh Research Center, has developed and field tested a spatial, spectral sensor for measuring the thickness of mineral deposits.
-
1/1/1995 - Conference papersIn addition to developing various types of cool-interface detection systems, the US Bureau of Mines is actively involved in developing a coal rib-thickness monitoring system for highwall mining applications. One particular system to detect the coal-air ...
