Environmental Impact Assessment of Mining Subsidence by Using Spaceborne Radar Interferometry [PDF]

, 2004
For underground mining, the extraction of coal or minerals can lead to the disturbance of the surface of the land. Surface structures may be damaged by tilting or lowering of the land surface as a result of ground subsidence.

Surface Subsidence Prediction Method for Coal Mines with Ultrathick and Hard Stratum

Advances in Civil Engineering, 2019
Overburden conditions consisting of ultrathick and hard stratum (UTHS) are widespread in China and other countries, but existing surface subsidence prediction methods ignore the strong impact of UTHS on surface subsidence.

Study on the destruction law of physical and shear properties of soil in mining disturbance

Scientific Reports, 2023
Underground mining activities can easily trigger surface subsidence and cause damage to surface soil. However, there is still a lack of studies on damaged soil, restricting ecological remediation in mining-induced subsidence regions to a certain degree ...

Monitoring of surface subsidence disasters and evolution laws caused by multiple mining activities in coal mines based on SBAS-InSAR

Geohazard Mechanics
In underground coal mining, surface subsidence disasters are likely to be induced. Especially, under the condition of multi-seam mining, the movement characteristics of the overlying strata are more complex.
