Insights from mining-induced seismic occurrence and migration signals based on surface subsidence and overburden movement

International Journal of Coal Science & Technology
In recent years, there has been an increasing incidence of overburden movements, resulting in surface subsidence, triggered by deep coal mining operations.

Simulation of Strata Failure and Settlement in the Mining Process Using Numerical and Physical Methods

Applied Sciences
Coal mining can cause the rupture of the overlying strata, and the energy released by large-scale fractures can therefore induce earthquake disasters, which in turn can cause more secondary disasters.

An evaluation of processing InSAR Sentinel-1A/B data for correlation of mining subsidence with mining induced tremors in the Upper Silesian Coal Basin (Poland)

E3S Web of Conferences, 2018
The Satellite Radar Interferometry is one of the common methods that allow to measure the land subsidence caused by the underground black coal excavation.

Dynamic prediction of coal and gas outburst risk based on quantitative analysis of stress–energy evolution and adaptive correction

Deep Underground Science and Engineering, EarlyView.
This study quantitatively analyzed the spatiotemporal evolution of stress redistribution ahead of the working face by integrating coal seam distribution, tectonic stress anomalies, gas pressure, and mining‐induced disturbances. An R‐value criterion for coal and gas outburst (CGO) risk assessment was established based on energy principles.

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Seismic mechanism induced by coordinated fracturing of sub-key strata under repeated mining and seismic mitigation effect of goafs

Meitan kexue jishu
Mining-induced seismicity, a type of non-natural seismic event triggered by mining activities, poses a major threat to the safety of coal mine production due to the rapid release of elastic energy and the potential damage to underground structures and ...

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

Geological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Statistical properties of seismic foreshocks and aftershocks associated with longwall mining: Implications from the Epidemic Type Aftershock Sequence model

Journal of Rock Mechanics and Geotechnical Engineering
The control and management of mining-induced seismic hazards have attracted ever-rising attention, especially in underground longwall coal mines, where continuous mining activities dynamically alter the stress states and induce seismic events.
