dc.description.abstract | Underground coal seam mining has been carried
out in the Upper Silesian Coal Basin, Poland, for
many years and with a simultaneous increase in exploitation
depth. Frequently, coal seams are not fully extracted
due to numerous reasons which lead to their
edges and remnants remaining in the rock mass. Even
in the case of the full extraction of a coal seam, mining
usually ends at the border of a protecting pillar to protect
underground or surface objects, sometimes at the border
of themining area, or some distance from the old goaf or
high throw fault. Extraction of subsequent coal seams in
an analogous range results in a cluster of coal seam
edges remaining. In the vicinity of the mentioned remainders,
the disrupted stress distribution is expected.
The infraction of the aforementioned equilibrium repeatedly
results in the occurrence of strong mining
tremors. The observations from the studied coal seam
no. 408’s longwall panel indicated that mining works
are able to disturb the present stress-strain equilibriumin
the area of the edges of other coal seams, even if they are
located at a greater vertical distance away. The seismological
parameters and distributions have been applied
for this purpose. | pl_PL |
