Development of an empirical ground-motion model for post-mining induced seismicity near Gardanne, France [PDF]

International audienceSince the closure of mining activities in 2003, the coal basin of Gardanne in South-East France has experienced thousands of small-magnitude earthquake events, mostly triggered by the flooding of mine workings.

Rockburst mechanism caused by the mining-induced drainage of confined water in deep extra-thick aquifer

Meitan xuebao
Extra-thick sandstone confined aquifer is widely spread in the overburden strata in Shaanxi and Inner Mongolia provinces. During coal mining, the water inflow in the working face is severe and the confined water level in the roof aquifer decreases ...

The influence of regional geological settings on the seismic hazard level in copper mines in the Legnica-Głogów Copper Belt Area (Poland)

E3S Web of Conferences, 2017
The current level of rockburst hazard in copper mines of the (LGOM) Legnica- Głogów Copper Belt Area is mostly the consequence of mining-induced seismicity, whilst the majority of rockbursting events registered to date were caused by high-energy tremors.

Classification of Mining Induced Seismicity at the Kiirunavaara Mine [Elektronisk resurs]

, 2022
The risk associated with mining induced seismicity and the related rock bursts has become one of the major threats to the safety and sustainability of mining at the Kiirunavaara mine, Sweden.

Self-induced seismicity due to fluid circulation along faults [PDF]

, 2013
International audienceIn this article, we develop a system of equations describing fluid migration, fault rheology, fault thickness evolution and shear rupture during a seismic cycle, triggered either by tectonic loading or by fluid injection.

Multiscale monitoring and analysis of complex rupture and source mechanisms of mining-related seismicity on fault networks

Journal of Rock Mechanics and Geotechnical Engineering
Mining-related seismicity poses significant challenges in underground coal mining due to its complex rupture mechanisms and associated hazards. To bridge gaps in understanding these intricate processes, this study employed a multi-local seismic ...

A comparison of seismic response to conventional and face destress blasting during deep tunnel development

Journal of Rock Mechanics and Geotechnical Engineering, 2019
A novel design of development face destress blasting was implemented during the construction of an experimental tunnel at great depth. A second tunnel was developed nearby using conventional blasting as a control.

Toward performance-driven seismic risk monitoring for geothermal platforms: development of ad hoc fragility curves

Geothermal Energy, 2018
Earthquakes, despite being a mostly natural phenomenon, may also be induced by a wide range of anthropogenic activities such as mining, fluid injection and extraction, hydraulic fracturing and geothermal reservoir processes.

Monitoring of Anthropogenic Seismicity in Italy: State of the Art

, 2018
In Italy the discussion about anthropogenic seismicity started after the deadly M6 Emilia earthquakes in 2012. Occurring these events in an area of gas and oil production, the question raised, whether exploitation induced crustal stress variations that ...
