This paper is devoted to a complex review of various monitoring networks operating in the eastern part of the Ostrava- Karviná Coal Basin. In the first place, there were systems for monitoring seismoacoustic emissions during coal extraction. Later a local seismic network was installed which encompasses partial arrays of seismic stations located in the individual mines underground. In addition, a special regional seismic network was established in order to ensure reasonable recordings of strong seismic events observed in this area. In 2001 an array was constructed with up to five surface seismic stations which monitor manifestations of rockbursts due to imposed dynamic loading on existing buildings at selected sites. Recently, a quite new monitoring system of accelerometers began operating, the purpose of which is to check the effects of rockbursts on surface structures. Using the output data of all monitoring systems, different graphs were constructed, which can faciliate geophysical interpretation of geodynamic processes in mines.
