Power spectra of quarry blasting works measured in different depths
Original language description
Vibrations generated by quarry blasting are the most intensive manifestation of technical seismicity. Comparative measurements of vibrations from blasting generated in open-pit mines were performed in the Jeroným Mine near Čistá (Czech Republic). A detailed evaluation of vibrations on underground spaces is very important here because this mine is a significant heritage site of medieval tin mining. The distance between the nearest feldspathic quarry named Krásno and the Jeroným Mine is 4.7 km east, Vítkov quarries (granite) is located north in the distance of 6.3 km. Maximum values from the nearest quarry Krásno are usually within the range of 10-3 10-2 mm.s-1. Prevailing frequency range of recorded waves is 1 - 6 Hz for both quarries. To qualify seismic loading of mine, one seismic station was located on the surface, the second one in the mine at a depth of about 30 m. Power spectra could be used for distinguishing, but the difference in spectra shapes is rather evident. Especially the difference is most explicit for the frequency range 70 - 100 Hz between power spectra of surface and underground records. Fitted trends were calculated for the mentioned frequency range of power spectra. Spectral time-frequency diagrams were also defined.
