Seismicity and Rock Burst Hazard Assessment in Fault Zones: a Case Study

The coal exploitation in the Upper Silesia region (along Vistula River) triggers strata seismic activity, characterized by very high energy, which can create mining damage of surface objects, without any noticeable damages underground structures. It is assumed that appearance energy events result faults’ activation vicinity excavation. This paper presents analysis a case study one mine, where during longwall panel no. 729, occurred faulty neighborhood. authors had analyzed cause presented events, described methods decreasing and applied prevention selected region. concluded 729 was rapid displacements on fault surface. fault’s movements arose overburden, about 250 m above excavated panel, they were strictly connected to cracking thick sandstone layer.
