The intensity of seismic waves’ vibrations is proportional to the weight of the applied explosive. If the vibrations are sufficientin energy, surrounding buildings can be damaged or destroyed. Evaluating the negative effects of the blasting operations and quantification of the seismic safety is nowadays very actual and a challenging problem. The article presents the results of the analysis as well as an evaluation on seismic safety of the objects during blasting in the quarry Kučín. The results the evaluation seismic effects blasting verified in a Kučín quarry are the methodological base for evaluating the seismic effects of blasting in all quarries in Slovakia.

Blasting has positive effects and negative impacts causing damage to surrounding civil objects. The intensity of seismic waves’ vibrations is proportional to the weight of the applied explosive. If the vibrations are suffcient in energy, surrounding buildings can be damaged or destroyed. Evaluating the negative effects of the blasting operations and quantifcation of the seismic safety is nowadays very actual and a challenging problem. The article presents the results of the analysis as well as an evaluation method of seismic safety of the objects during blasting work held by the seismic waves’ attenuation law in Dubina quarry. The results of the evaluation of seismic effects of blasting verifed in a Dubina quarry are the methodological base for evaluation of the effects of seismic blasting in all quarries in Slovakia.

The impact of blasting operations is accompanied by positive and also negative after-effects. Vibrations, activated by explosion, help to disturb the rocks what represents a positive effect on one hand and endanger surrounding buildings and other properties on the other hand as a negative effect. If the vibrations are large enough, than the ambient objects could be damaged or destroyed. Negative effects depend on their range and strength. Vibration intensity of seismic waves is proportional to weight of the explosive used. Recently, negative effects of the blasting operations and quantification of the seismic safety is highly actual and challenging problem. The article represents results of the blasting operation monitoring in Maglovec quarry.

Obserwacja propagacji energii sprężystej w masywie skalnym zapewnia wiarygodną informację na temat stanu naruszenia masywu. W aspekcie oceny operacyjnej naruszenia masywu skalnego wskutek użycia materiałów wybuchowych występuje potrzeba rozwinięcia dynamicznych metod impulsowych. Zastosowanie technik komputerowych do obróbki sygnału sejsmicznego umożliwia rozwinięcie impulsowych metod dynamicznych w odniesieniu do badań masywu skalnego dla celów oceny geotechnicznej. Jedną z takich metod jest tomografia komputerowa z wykorzystaniem danych pomiarowych. Jednym z podstawowych składników takiej tomografii jest analiza przestrzenna, stosowana do przedstawiania i wizualizacji położenia miejsc nieciągłości, przydatna w planowaniu przedsięwzięć przemysłowych i naukowych. W artykule przedstawiono pomiary laboratoryjne i analizę przestrzenną pomierzonych danych dla przypadku lokalizacji nieciągłości i tworzenia przestrzennego modelu masywu skalnego.

Observation of elastic energy propagation in rock massif provides credible information of complex rock massif violating. In aspect of operative judging of massif violating by using explosive, is necessary advancement for creation in using impulse dynamic method. Application of computer technologies to seismic signal operation is a viable way of increment a possibilities of impulse dynamic methods in rock massif for geotechnical judging. One of usable way is a computer tomography using for measured data manipulation. One of elemental component of computer tomography is a spatial analysis, which is used to presentation and visualization of current location of discontinuities in case of planned industrial and scientific activities. In this paper laboratory measurements and spatial analysis of measured data are presented in case of discontinuities location and rock massif spatial model creation.
