7/1/2008 - Conference papersThis paper describes a case study where a surface-based microseismic system, using triaxial geophones in boreholes drilled from the surface, was deployed at a large limestone mine.
6/1/2008 - Peer reviewed journal articlesThis paper describes the 3D velocity tomograms that were generated to image the stress redistribution around an underground coal longwall panel to produce a better understanding of the mechanisms that lead to ground failure, especially rockbursts.
1/1/1997 - Peer reviewed journal articlesIn an effort aimed at monitoring mining-induced stress changes that may influence ground failure, the U.S. Bureau of Mines conducted a series of active 3-D seismic tomographic surveys at the Homestake (Lead, South Dakota) and Lucky Friday (Mullen, Idaho...
1/1/1976 - Reports of InvestigationsA seismic system which utilizes in-mine geophones to detect trapped miners has been developed. Tests at the Bureau of Mines safety research mine at Bruceton, Pennsylvania, and at two operating mines indicate such a system has a maximum detection range i...
