Abstract

The problem of mining-induced seismicity in hard rock mines has become more recurrent and significant in underground mines since mining is reaching greater depths as a consequence of the depletion of shallow reserves. This has been a cause of concern for the Cuiabá Mine, where seismicity has increased with the advancement of the mine depth and more cases of fall of grounds have been reported. Thus, in order to avoid production losses, damage and to ensure the safety of workers of this mine, seismic hazard assessment is necessary to the mine project management. For this purpose, this paper focuses on: (i) identifying and understanding of the dominant rock mass failure mechanisms in critical areas of the Cuiabá mine and (ii) developing a preliminary quantitative methodology for assessing the seismic hazard of this mine. Hence, areas with high potential for seismic risk can be identified during mine excavation.
