On 19 March 2013, a tremor shook the surface of Polkowice town where the Rudna Mine is located. This event, of ML = 4.2, was the third most powerful seismic event recorded in the Legnica Głogów Copper District (LGCD). Inhabitants of the area reported that the felt tremor was bigger and lasted longer than any other ones felt in the last couple of years. …

Mining-induced seismicity (MIS) is unpredictable and has the potential to be damaging; therefore, it is important to study it to gain insight into how rock damage develops in a mine. A dataset of 1906 mining-induced events was recorded at the Trail Mountain Mine (TMM). These events cluster on Panel 13, the active panel during data collection. In this thesis, …

Coal mining in thick-hard roof areas leads to frequent high-energy seismicity and may even induce coal–rock dynamic disasters such as rockburst. It is important to explore the focal mechanism of mining-induced seismicity to understand the failure behaviour of the coal–rock mass and the characteristics of the stress field. It is …

Considering two typical mining-induced strong tremors as examples, the interaction mechanisms between mining-induced tremors and rockbursts were analysed. The results demonstrated that the inversion method is reliable and can be used as a useful supplement for the analysis of mining-induced tremors in coal mines.
