dc.description.abstract | Underground mining of coal seams in the Upper Silesian Coal Basin
in Poland is accompanied by seismic activity of varying magnitude.
The investigations which have been performed for several years distinguished
high energy mine tremors connected directly with mining or
coupled with geological structures, such as large faults. In mined seams,
local fault zones occur. Faults in these zones are usually small, with
throws comparable with coal seams thicknesses. Local fault zone may be
responsible for the occurrence of high energy tremors as well as large
faults, as presented in this article. An analysis of source mechanism of
high energy tremors generated during longwall mining of the coal seam
No. 510, with presence of a local fault zone, in one of the Polish hard
coal mines in the Upper Silesian Coal Basin was performed. For this
purpose, the seismic moment tensor inversion method was used. In most
of foci, the process of shear predominated. Determined nodal plane parameters
were correlated with parameters of faults forming the local fault
zone. High energy tremors were generated mostly by dislocations on
faults of the local fault zone. Weakening of roof rocks in the neighborhood
of local fault zone takes an important role too, and was responsible
for share of implosion in the focal mechanism. | pl_PL |
