矿区形变区及中心形变速率研究
Study on subsidence area and its centre change rate
摘要
Abstract
The second mine, third mine, fifth mine and sixed mine in HEBI city in Henan Province are test study areas. According to the technical principles of the permanent-scatterer differential interferometry ( PS-In- SAR) , we use 12 scenes of ENVISAT ASAR data timing SAR images from 2008 to 2010, and the data is pro- cessed in the IPTA module in GAMMA software. The experimental results shows that there are 6 areas that have large surface deformation and coincide with the actual mining area location. The cumulated displacement of those points is up to 60 mm in the period of 2008--2010, and the largest deformation rate is 25 mm/a. Other deformation rate is between 16 -20 mm/a.关键词
