Research on characteristics, induced disasters, and prevention technology of mining-induced seismicity in China

采矿与岩层控制工程学报
In view of the increasingly prominent risk of mining-induced seismicity during the westward shift of coal mining development in China, this paper systematically analyzes the distribution patterns, typological characteristics, and occurrence mechanisms of

ANALYSIS OF THE GEOMETRY OF SURFACE DEFORMATIONS CAUSED BY INDUCED TREMORS IN THE AREA OF UNDERGROUND COPPER MINING [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Induced seismicity by human operations such as mining is usually unpredictable due to the sudden and unexpected character of this phenomenon. The effects of seismic events on the surface, i.e.

Distribution of Strongest Aftershock Magnitudes in Mining-Induced Seismicity

Frontiers in Earth Science, 2022
The paper considers the distribution of magnitudes of the strongest aftershocks–depending on the time after the main shock–that occur during the extraction of minerals in tectonically loaded rock massifs.

Mechanisms, monitoring, prevention and control of deep coal mining-induced seismicity: Study of typical cases in China

International Journal of Mining Science and Technology
Mining-induced seismicity is a distinct category of anthropogenic earthquakes, with their incidence increasing with mining depth. This study is grounded in mining-induced seismic data and technical solutions from typical mines in China.

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Non-Parametric Characterisation of Mining Induced Seismic Sources [PDF]

Proceedings of the Sixth International Symposium on Rockburst and Seismicity in Mines Proceedings, 2005
Statistical properties of seismicity are expressed by probabilistic distributions of seismic source parameters, out of which the magnitude distribution is the most important in the seismic hazard analysis. Owing to its complexity the magnitude distribution of mining-induced events cannot be accurately represented by any of the known parametric models ...

Probabilistic prediction of rate‐dependent rock strength using natural gradient boosting and Gaussian process regression

Deep Underground Science and Engineering, EarlyView.
Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic
