Conducting mining operations in fault zones is a very challenging task, both from a technological perspective and also due to the safety of the miners. Therefore, it is essential to determine the impact of mining parameters on the possibility of fault activation, which in many cases leads to high seismic activity. The article presents the results of numerical analyses of the impact of longwall mining in the vicinity of tectonic faults on the state of stress in the rock masses. The authors demonstrated the influence of the advancement of the longwall face and its direction on the risk of rock burst, both for mining conducted in the footwall and hanging wall.
