<abstract xmlns="http://www.w3.org/1999/xhtml">This paper presents average normalised acceleration response spectra calculated for mining induced seismic events which were recorded by twenty-one stations located in the area of Legnica-Glogow Copper District (LGCD). In this paper, 5.246 ground motion signals with peak ground acceleration (PGA) over 0.03 m/s2 were analysed. The ground motions were caused by 1.886 mining events with <italic>ML</italic> greater than 2 (energy > 105J), which occurred from 2004 to 2015. The design response spectra were estimated based on average normalised acceleration response spectra. Further analysis of results shows that the shape and amplitude of response spectra are strongly dependent on the event magnitude, the epicentral distance and the location of the stations. The obtained response spectra could be used for computing seismic forces which have impact on buildings response to ground motions caused by mining events in LGCD.</abstract>
