Understanding mining subsidence under high-intensity mining can provide a basis for mining-induced damage assessment, land remediation in a subsidence area, and ecological reconstruction in vulnerable ecological regions in Western China. In this study, the mining subsidence status of Shendong Coalfield was investigated and analyzed using two-pass differential interferometric synthetic aperture radar (DInSAR) technology based on high-resolution synthetic aperture radar data (RADARSAT-2 precise orbit, multilook fine, 5 m) collected from 20 January 2012 to June 2013. Surface damages in Shendong Coalfield over a period of 504 days under open-pit mining and underground mining were observed. Ground deformation of the high-intensity mining working faces 22201-1\/2 in Bu\u2019ertai Mine, Shendong Coalfield was monitored using small baseline subset (SBAS) InSAR technology. (1) DInSAR detected and located 85 ground deformation areas (including ground deformations associated with past-mining activity). The extent of subsidence in Shendong Coalfield presented a progressive increase at an average monthly rate of 13.09 km2 from the initial 54.98 km2 to 225.20 km2, approximately, which accounted for 7% of the total area of Shendong Coalfield; (2) SBAS-InSAR reported that the maximum cumulative subsidence area reached 5.58 km2 above the working faces 22201-1\/2. The advance speed of ground destruction (7.9 m\/day) was nearly equal to that of underground mining (8.1 m\/day).<\/jats:p>","DOI":"10.3390\/rs8110951","type":"journal-article","created":{"date-parts":[[2016,11,16]],"date-time":"2016-11-16T16:23:04Z","timestamp":1479313384000},"page":"951","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Investigation on Mining Subsidence Based on Multi-Temporal InSAR and Time-Series Analysis of the Small Baseline Subset\u2014Case Study of Working Faces 22201-1\/2 in Bu\u2019ertai Mine, Shendong Coalfield, China"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3325-7318","authenticated-orcid":false,"given":"Chao","family":"Ma","sequence":"first","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"Key Laboratory of Mine Spatial Information Technologies of SBSM, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Xiaoqian","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Henan Polytechnic University, Jiaozuo 454000, China"},{"name":"Key Laboratory of Mine Spatial Information Technologies of SBSM, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Yali","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing Science and Technology, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Xiaoke","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Public Administration, Hohai University, Nanjing 210098, China"}]},{"given":"Zengzhang","family":"Guo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mine Spatial Information Technologies of SBSM, Henan Polytechnic University, Jiaozuo 454000, China"}]},{"given":"Youfeng","family":"Zou","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mine Spatial Information Technologies of SBSM, Henan Polytechnic University, Jiaozuo 454000, China"}]}],"member":"1968","published-online":{"date-parts":[[2016,11,16]]},"reference":[{"key":"ref_1","first-page":"59","article-title":"Application of PS-InSAR technique in the deformation monitoring in mining collapse areas in Beijing","volume":"21","author":"Chen","year":"2010","journal-title":"Chin.
