The seismic hazard in Polish copper mines has remained continuously at a high level, generating a relatively large number of accidents and negatively affecting the continuity of the exploitation process. To minimize the threat, a number of preventive actions are taken to reduce the ability of the rock mass to accumulate stresses, which should ultimately result in a reduction in the number and energy of seismic phenomena. Unfortunately, as previous experience shows, the effectiveness of preventive measures is sever...

One of the major problems associated with excavation of the copper deposits in underground mines in Poland is the relatively high level of seismic activity. Numerous high-energy tremors can negatively affect the stability of underground workings and can have a destructive impact on the infrastructure located at the surface as well. As predicted, the seismic activity increases along with the depth of mining operations. Therefore, in order to face these threats, a number of organizational and technical prevention me...
