10/22/2016 - Research projectsA project to implement in-mine seismic monitoring techniques in coal mines to evaluate and demonstrate potential mine safety benefits of this technology.
-
9/1/2016 - Reports of InvestigationsA Report of Investigations presenting five strategies for detecting and recording seismic activity associated with deep longwall coal mining.
-
8/23/2016 - Contracts and cooperative agreementsA contract to explore early detection of rock movement signaling imminent underground space or pit wall collapse in mines, which has the potential to prevent loss of life and serious injuries from mine disasters.
-
7/18/2016 - Contracts and cooperative agreementsA contract to investigate and report on the state-of-the-art in mine seismic monitoring systems and methodologies as applied to deep coal mining.
-
12/1/2013 - Peer reviewed journal articlesSeismic monitoring provides a useful means for detection and evaluation of events resulting from mining activity.
-
3/1/2012 - Peer reviewed journal articlesThis paper describes the research conducted to quantify a relationship between measured values of radiated seismic energy and peak explosive pressure generated.
-
9/1/2009 - Peer reviewed journal articlesMethods of improving seismic event locations were investigated as part of a research study aimed at reducing ground control safety hazards. Results obtained using different velocity models are compared.
-
7/1/2008 - Conference papersThe objective was to determine whether a qualitative but coherent redistribution of velocity, indicating change in location of induced stress, could be imaged as mining occurred in known locations by using a local earthquake tomography software.
-
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.
