Description:
In this paper, the Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) technology
is adopted to monitor the Line of Sight (LOS) displacement of Fushun West Opencast Coal
Mine (FWOCM) and its surrounding areas in northeast China using Sentinel-1 Synthetic
Aperture Radar (SAR) images acquired from 2018 to 2022. The spatial-temporal evolution of
urban subsidence and the south-slope landslide are both analyzed in detail. Comparison with
ground measurements and cross-correlation analysis via cross wavelet transform with monthly
precipitation data are also conducted, to analyze the influence factors of displacements in
FWOCM. The monitoring results show that a subsidence basin appeared in the urban area near
the eastern part of the north slope in 2018, with settlement center located at the intersection of
E3000 and fault F1. The Qian Tai Shan (QTS) landslide on the south slope, which experienced
rapid sliding during 2014 to 2016, presents seasonal deceleration and acceleration with
precipitation, with the maximum displacement in vicinity of the Liushan paleochannel. The
results of this paper have fully taken in account for the complications of large topographic
relief, geological conditions, spatial distribution and temporal evolution characteristics of
surface displacements in opencast mining area. The wide range and long time series dynamic
monitoring of opencast mine are of great significance to ensure mine safety production and
geological disaster prevention in the investigated mining area.
