dc.description.abstract | Seismic and geodetic studies were carried out before, during, and after underground exploitation of
a coal bed in Katowice – Kleofas Coal Mine, located in the Upper Silesia Coal Basin, Poland. Development
of a subsidence trough was completed approximately 3 months after passage of a longwall exploitation
in the coal seam. This was the time required for the subsidence trough to appear on the surface, which
was confirmed by levelling measurements. Sharp changes in the elastic parameters were observed on
each profile during subsidence trough development. This observation can result from changing tension
and compression forces caused by increase and/or decrease of the elastic parameters of the rock mass.
After completion of subsidence trough development, the rock mass appeared to return to its isotropic state
and the observed changes ceased. Some minor fluctuations were noted, but they probably resulted from
changes in groundwater levels, which might have affected the measured parameters. | pl_PL |
