This paper describes experimental measurements of seismic effect originated during demolition of a reinforced-concrete winding tower in the area of former company “Rudné doly” in Zlaté Hory (the Czech Republic). Seismological measurement was performed on the profile of 250 m long for the purpose to obtain the information on the effect of vibration in the near zone. Recorded wave patterns caused by demolition can be divided into three phases - the first phase caused by blasting, the second one caused by settling of a separate part of the tower to its foundations and gradual tilting, and the third phase caused by falling of a separate part of the tower to the ground. Significant harmonic vibration was identified during the second phase of demolition. In order to get more detailed information on the source of recorded harmonic vibration during second phase, analysis of resonance frequency of soil layers along the profile of the length of 210 m was performed. Experimental measurement of seismic noise was carried out at 11 points and resonance frequency was determined using the HVNR method.
