Satellite radar interferometry for mine subsidence monitoring
Australia is one of the world’s leading mineral resource extraction and exporting nations. Underground mining can cause ground surface displacement, which may in turn have serious impacts on the environment or man-built facilities. This paper describes the results of a study into the feasibility of surface subsidence (caused by underground coal mining) monitoring using differential interferomet...
متن کاملDifferential Radar Interferometry for Mine Subsidence Monitoring
The history of mining disasters includes cases of subsidence and collapse into workings, and also a number of inrushes into underground mines, where deficiencies in surveying, or in maintenance and interpretation of plans, were prime factors. The most recent incident in Australia was at the Gretley Colliery in NSW, in 1996. The most recent such incident in the USA was at the Quecreek Mine in So...
متن کاملSurface subsidence induced by the Crandall Canyon Mine (Utah) collapse: InSAR observations and elastoplastic modelling
S U M M A R Y The Crandall Canyon Mine, Utah, collapse in 2007 August resulted in a total of nine fatalities. We processed data from the ALOS satellite acquired before and after the collapse to quantify surface subsidence associated with the collapse to better understand the collapse process. The deformation shows a steep V-shaped pattern of subsidence with slight asymmetry.We compare the fit o...
متن کاملInvestigation on Health Effects of an Abandoned Metal Mine
To investigate potential health risks associated with exposure to metals from an abandoned metal mine, the authors studied people living near an abandoned mine (n=102) and control groups (n=149). Levels of cadmium, copper, arsenic, lead, and zinc were measured in the air, soil, drinking water, and agricultural products. To assess individual exposure, biomarkers of each metal in blood and urine ...
