Study on the Surface Subsidence Trend of Fill Mining in Underground Mines With Different Mining Depths

Advances in Civil Engineering
The extraction of underground mineral deposits can cause surface subsidence, which will bring danger to surface buildings or structures. In this paper, the Panlong lead–zinc mine in Guangxi, China, was taken as an example to analyze the correlation ...

Monitoring of Surface Subsidence of the Mining Area Based on SBAS [PDF]

Journal of Computers, 2014
This paper has collected 7 scenes of L band PALSAR sensor radar data of a mine in FengCheng city, jiangxi province, using the Small-baseline Subset (SBAS) method to invert the surface subsidence of the mine. Baselines of interference less than 800m has been chosen to constitute short baseline differential interference atlas, using pixels whose average ...

Complex Surface Deformation of the Coalfield in the Northwest Suburbs of Xuzhou from 2015 to 2020 Revealed by Time Series InSAR

Canadian Journal of Remote Sensing, 2021
The coalfield in the northwest suburbs of Xuzhou has suffered from extensive land subsidence; however, the temporal nonlinearity and corresponding spatial variation of its surface deformation has not been adequately explored.

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.

SURFACE SUBSIDENCE MONITORING AND ANALYZING IN BEIJING BASED ON INTERFEROMETRIC POINT TARGET ANALYSIS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Temporal and geometrical decorrelation often prevents SAR interferometry from being an operational tool for surface deformation monitoring. Moreover, atmospheric disturbances can strongly compromise the accuracy of the results.

Estimation of surface subsidence during tunneling

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The limitations of the traditional methods of assessing the surface subsidence and the state of structures and natural objects in mining operations are shown. An innovative approach to predicting the surface subsidence during tunneling is proposed.
