The copper ore deposit in Poland is mined by three underground mines using mainly group blasting technology, which serves as the active rock-burst prevention, aiming at distressing rock mass by means of vibration provoked with blasting. The mines belong to KGHM Polish Copper Joint Stock Company (KGHM). The paper objective was to determine the influence of the length of after-group blasting waiting time on provoked seismic energy in one of the KGHMпїЅs copper ore mine. It was necessary to investigate, evaluate and ...
