Environmental Impact Evaluation of Underground Mining Activities Using InSAR Technique

摘要

This papers deals with the study of environmental impact assessment of underground coal mining activities. InSAR technique was utilized in this paper to monitor the mine subsidence caused by underground mine extractions. The study area is in Chongqing municipality in west of China, and the studied coal mine has been founded for more than 80 years. Two ALOS PALSAR images were used in this study; the time interval of two image acquisition time is approximately two years and one month. The underground mining-induced subsidence could be easily identified from the unwrapped interferogram, and the maximum subsidence value was around 32.8 centimeters.
