The deformation monitoring and mechanical behavior analysis of the mining area helps reveal the typical mountain deformation and failure mechanism caused by underground mining activities and reduce the risk of mountain collapse in the mining area. In this manuscript, a research method for mountain stability in mining areas is proposed, which combines InSAR deformation monitoring with numerical analysis. Based on the high-precision deformation information obtained by DS-InSAR and the landslide range, a three-dimensional explicit finite difference numerical analysis method was used to reconstruct the landslide model. According to the layout of the coal mining working face, the variation mechanism of overlying stratum stress and the mountain slip in the coal mining process is inverted, and the mechanism of mountain failure and instability in the mining area is analysed. Based on the sentinel data, the experiment performed time series monitoring and inversion analysis of the mountain collapse in Nayong, Guizhou, China. The results show that mining activities a certain distance from the mountain will affect mountain stability, and there are specific mechanisms. From 2015 to 2017, the stress redistribution of overlying strata above the goaf area resulted in dense longitudinal cracks in the landslide body due to coal mining. The mountain is in a continuous damage state, and the supporting force to prevent collapse continues to decrease, resulting in a gradual decrease in landslide stability. Both the time series DS-InSAR monitoring results and numerical simulation results verify the actual occurrence and development of the on-site subsidence.<\/jats:p>","DOI":"10.3390\/s22207811","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T03:43:58Z","timestamp":1665978238000},"page":"7811","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Instability Monitoring and Numerical Analysis of Typical Coal Mines in Southwest China Based on DS-InSAR"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6050-2411","authenticated-orcid":false,"given":"Maoqi","family":"Liu","sequence":"first","affiliation":[{"name":"School of Earth Science and Spatial Information Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"},{"name":"College of Resource Environment and Safety Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sichun","family":"Long","sequence":"additional","affiliation":[{"name":"College of Resource Environment and Safety Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenhao","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Resource Environment and Safety Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Liu","sequence":"additional","affiliation":[{"name":"Guizhou University Mining College, Mining College of Guizhou University, Guiyang 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liya","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Resource Environment and Safety Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuanguang","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Resource Environment and Safety Engineering, Hunan University of Science and Technology, Xiangtan 411201, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,14]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Research on surface deformation of ordos coal mining area by integrating multitemporal D-InSAR and offset tracking technology","volume":"4","author":"Yao","year":"2021","journal-title":"Sens.
