Abstract
In Bobrek hard coal mine located in the area of Upper Silesia Coal Basin, two types of tremors can be distinguished. The first type is seismic shocks occurring in the vicinity of longwall mining fronts, which are the result of mining works. The second type of tremors is related to the location of renewed seismogenic structures. The article presents a collection of tremors recorded during the exploitation of the longwall 3 in a seam No. 503 from April 2009 to July 2010. An attempt was made to relocate tremors to separate clusters that could correspond to microtectonic structures. In order to group events into more spatially ordered structures, the collapsing method was used. The results of relocation after the collapsing procedure were shown on the whole data set. The linear structures responsible for the generation of shocks related to the progress of the mining front together with those indicating tectonic microstructures activated as a result of mining operations were presented. © EAGE Publications BV 2021.
