Mining-induced seismicity in the Nottinghamshire Coalfield
Quarterly Journal of Engineering Geology, 1993Abstract Between July 1989 and August 1990 over 130 earth tremors were felt and reported by people living in the Edwinstowe district of Nottinghamshire. In order to determine whether the tremors were caused by mining activity, a small aperture array of eight temporary surface seismometer stations was established around the area of coal ...

A WADATI FILTER FOR MINE-INDUCED SEISMICITY
South African Journal of Geology, 2009We introduce a procedure based on Wadati diagrams to assess and improve the consistency of P- and S-wave travel-time picks with the assumption of propagation at constant wave-speed. Wadati diagrams are plots of S-P vs P-wave travel-times and they are expected to lie along a straight line for a medium of constant velocity.

Seismological Research Letters, 2013
Online Material: Additional synthetic test results, plots, and tables. The automated location of seismic events is an important and challenging task in microseismic monitoring applications (e.g., to analyze induced seismicity following oil/geothermal field exploitation and mining operations), where we deal with a large number of seismic events and ...

Mining-induced seismicity: Seismic measurement using multiplet approach and numerical modeling
International Journal of Coal Geology, 2006The volume of influence of mining works is essentially determined from in situ observations, field measurements (particularly surface subsidence measurements) as well as from numerical investigations. Seismic monitoring is the primary requirement for mining in rock-burst environment.

Seismicity in mines, in general, depends on depth, production rate, mining geometry and geological discontinuities such as dykes, faults etc. and on ambient tectonic stress field. One or combination of the above factors may contribute significantly to mining seismcity in any specific case (Gibowicz and Kijko, 1994; Mendecki, 1997; Holub, 1997; Holub et.

Mining-Induced Seismicity in the Saarland, Germany
Pure and Applied Geophysics, 2009Coal mining in the Saar mine, Germany, is accompanied by mining-induced seismic events. Strong events occur only in certain areas of the mine, other areas exhibit almost no seismicity. Shear events occur simultaneously to non-shear events. The shear events occur in different depths but their epicenters do concentrate in bands.

Space-time Interaction Amongst Clusters of Mining Induced Seismicity
pure and applied geophysics, 1996Elementary cluster analysis of induced seismicity in a South African gold mine has shown that there is a clear interaction amongst the clusters: and that the level of the interaction is a function of the distance. The clustering algorithm used is an adaptation of the single-link cluster analysis which considers both three-dimensional space and time.

Mining induced seismicity in the North Staffordshire Coalfield, England
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980Abstract Mining induced seismicity associated with long-wall coal extraction in North Staffordshire, England, has been investigated in order to establish the cause and mechanism of the seismicity. The study shows that seismicity is directly caused by active mining with earth tremor hypocentres moving in unison and in advance of the face.

Passive seismic tomography using recorded microseismicity: Application to mining-induced seismicity
Geophysics, 2018ABSTRACT Microseismicity is recorded during an underground mine development by a network of seven boreholes. After an initial preprocessing, 488 events are identified with a minimum of 12 P-wave arrival-time picks per event. We have developed a three-step approach for P-wave passive seismic tomography: (1) a probabilistic grid search ...
