Monitoring Longwall Mine Subsidence and Far-field Displacements Using Multi-wavelength Radar Interferometry
This study uses the spaceborne radar interferometry technique to monitor ground subsidence and far-field displacement due to underground longwall mining in the Southern Coalfields of New South Wales, Australia. The radar images acquired by the European ENVISAT/ASAR and the Japanese ALOS/PALSAR sensors were used to compute the terrain deformation. ASAR and PALSAR sensors use microwave signals in...
متن کاملApplication of Repeat-pass DInSAR and GIS for Underground Mine Subsidence Monitoring
This research used both ERS and JERS-1 images to investigate the feasibility of differential radar interferometry (DInSAR) for mine subsidence monitoring in the state of New South Wales, Australia. DInSAR results are analysed and validated with the aid of Geographic Information System (GIS) tools. The drawbacks of using interferometric measurements for mine subsidence monitoring are discussed. ...
متن کاملQuantitative Subsidence Monitoring: The Integrated InSAR, GPS and GIS Approach
Errors in radar satellite orbit determination are common problems in radar interferometry (InSAR). For example, when trying to locate a radar test site with known geographic coordinates using the geocoding information in SAR image (the latitude and longitude of the four image corners), the location may be well away from the true position. Another example is when there is indeed a significant si...
متن کاملA Study of Mine-Related Seismicity in a Deep Longwall Coal Mine
This study involves seismic monitoring of a deep coal mine. The purpose is to examine the processes responsible for induced seismicity. A seismic network consisting of five threecomponent short-period seismometers located above the mine recorded the seismic data. The events discussed here occurred from March 1, 2009 until April 7, 2011 during the mining of three longwall panels and the data was...
متن کاملField study of longwall coal mine ventilation and bleeder performance
Longwall coal mine operators in the U.S. are required to ventilate multipanel longwall districts, but may have little or no knowledge about what happens to the ventilation air between the inlet evaluation points (IEPs), bleeder evaluation points (BEPs) and bleeder fans. The effectiveness of bleeder performance can directly influence the ability of a ventilation system to remove and dilute coal ...
