摘要
随着经济的不断发展,对能源需求的扩大,山西省浑源县煤矿大规模开采对当地环境造成了严重的破坏。基于2007年6月-2013年4月的36景ALOS/PALSAR与2012年1月-2013年4月10景RADARSAT-2影像数据,利用时序InSAR技术获取了浑源县年形变速率与形变时间序列结果,分析了浑源县矿区地表形变与煤矿开采的时空演变关系。研究结果表明,浑源县地表形变可划分为49个形变区域,且7 a间均呈持续沉陷状态,当地房屋出现不同程度损坏,浑源县在东部、北部、西北部形成了三大沉降漏斗群,且形变量级与范围呈加剧趋势。形变结果与煤矿开采治理范围在空间上一致性较高,煤矿开采是造成地表沉陷的主要原因。
As the continuous development of economy requires more energy,the coal is mined in a larger scale in Hunyuan County of Shanxi Province,which causes serious damage to the local environment.Based on 36 ALOS/PALSAR images from June 2007 to April 2013 and 10 RA-DARSAT-2 images from January 2012 to April 2013,we used the time-series InSAR technology to obtain the sequential results of deformation rate and time-series in Hunyuan County,and analyzed the spatio-temporal evolution relation of surface deformation and coal mining in this region.The findings suggest that the surface deformation in Hunyuan County can be divided into 49 areas and its continuous subsidence has been ob-served for seven years.As a consequence,the local houses have been damaged in varying degrees.Three major subsidence funnel groups formed in the east,north and northwest of Hunyuan County.Their deformation magnitude and range show an increasing trend.The deformation results are highly consistent with the treatment scope of coal mining in space,which means that coal mining is the main reason for surface subsidence.
