The coal exploitation in the Upper Silesia region (along the Vistula River) triggers the strata seismic

activity, characterized by very high energy, which can create mining damage of the surface objects, without

any noticeable damages in the underground mining structures. It is assumed that the appearance of the

high energy seismic events is the result of faults’ activation in the vicinity of the mining excavation. This

paper presents the analysis of a case study of one coal mine, where during exploitation of the longwall

panel no. 729, the high energy seismic events occurred in the faulty neighborhood. The authors had analyzed

the cause of the presented seismic events, described the methods of energy decreasing and applied

methods of prevention in the selected mining region. The analysis concluded that the cause of the high

energy seismic events, during the exploitation of the longwall panel no. 729 was the rapid displacements

on the fault surface. The fault’s movements arose in the overburden, about 250 m above the excavated

longwall panel, and they were strictly connected to the cracking of the thick sandstone layer.
