Selected geological factors impacting effects of induced seismicity on surface in conditions of Ostrava-Karvina coalfield in the Czech Republic

Popis výsledku v původním jazyce

Underground exploitation of hard coal deposit in Ostrava-Karvina Coalfield which is the Czech part of Upper Silesian Coal Basin is accompanied by induced seismicity. This seismicity can be manifested negatively by rock bursts occurrence in underground workings and/or by vibration on the surface. The magnitude of surface vibration can be influenced by several factors. The basic factors are geological properties of rock mass - the thickness and the quality of overburden of Carboniferous strata and the level of underground water. In the paper authors analyse possible impact of these factors on surface vibration in conditions of Ostrava-Karvina Coalfield. The influence of rock burst and seismicity on surface is being observed by a network of standard underground and surface seismic stations and interpreted since late 1990?s. In previous few years the particle velocity was measured by mobile seismic stations on Earth's surface in selected localities.
