Summary: Mine landslides are geological disasters that occur frequently and cause significant harm globally. Understanding their formation mechanisms and kinematic processes is crucial for preventing and controlling mine geological disasters and ensuring mine production safety. This study investigated the 7.26 landslide in the Fushun West Open-pit Mine in China, using detailed investigations, InSAR monitoring, and numerical simulations. The study identified the mechanism of landslide formation, inverted its kinematic process, and summarized its disaster evolution process.

Summary: This study reports on a rain-induced landslide that occurred in the Fushun west open pit in China in 2016. The failure characteristics and formation mechanism of the landslide were explored through field investigations, laboratory tests, and numerical analyses. The study revealed that heavy rainfall triggered the landslide and the process of landslide formation can be divided into several stages. The findings contribute to the understanding of landslide mechanisms and can be applied for evaluating slope stability and early identification of open-pit mines, both active and inactive.

Summary: This paper adopts Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) technology 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. The study analyzes the spatial-temporal evolution of urban subsidence and the south-slope landslide. Comparison with ground measurements and cross-correlation analysis with monthly precipitation data is conducted to analyze the influence factors of displacements in FWOCM. The results are important for ensuring mine safety production and geological disaster prevention in the investigated mining area.

Summary: Reservoir landslides pose a significant threat to reservoir safety. Understanding the deformation characteristics and mechanisms of these landslides is crucial for assessing their stability and preventing secondary disasters. In this study, the authors analyzed the deformation characteristics and reactivation mechanism of the Wangjiashan ancient landslide during the initial impoundment of the Baihetan Reservoir region. They found that the landslide slowly deformed before impoundment, but impoundment itself drove further deformation. The rise in reservoir water level resulted in bank collapse at the landslide toe, followed by creep deformation and overall sliding. Moreover, the study revealed that the WJS landslide is a buoyancy weight-reducing landslide, where the reservoir water buoyancy acts on the resisting section and reduces its resisting force, leading to rapid sliding.

Summary: In this study, SAR technology and topographic information were used to analyze landslide deformation near the reservoir of the Gushui Hydropower Station. A new method was proposed to extract effective deformation information, which significantly improved landslide identification and analysis in complex terrain. The results showed the dominant role of cumulative rainfall in causing landslide deformation, with deformation acceleration occurring about 12 days after peak precipitation.

Summary: This study presents a detailed case analysis of the Dagushan Iron Mine and investigates the fracturing mechanism through numerical modeling. The excavation of a certain bench led to fault activation, shear band formation, and severe damage to the roadway and rock slope. Control measures involving slope cutting are proposed and validated using the numerical model, demonstrating their feasibility and practicality.

Summary: On February 26, 2021, the ancient Moli landslide in Guoye town, Zhouqu County, Gansu Province, China, was reactivated. The reactivated landslide had a volume of approximately 2120 x 10(4) m(3) and was classified as a remote accumulation layer landslide in a deep superlarge fault fracture zone. Through systematic field investigations and engineering mapping, the deformation characteristics and failure mechanisms of the landslide were studied. The complex geological structure and landform of Zhouqu County, along with multiple secondary landslides, contributed to the particularly complex failure mechanism of the landslide. Strengthened monitoring and comprehensive control measures are needed for this type of landslide.

Summary: Since the impoundment in 2003, variations in reservoir water level and seasonal precipitation have reactivated or accelerated many landslides in the Three Gorges Reservoir area. A study on the Baijiabao landslide reveals a step-like pattern of annual movement, influenced by the daily variation of reservoir water level and cumulative rainfall in the previous week. The movement of the landslide is closely associated with hydraulic factors including rainfall and changes in reservoir water level.

Summary: This paper describes the reactivation of an old landslide in Wushan County, Chongqing, China, which was caused by engineering disturbance and heavy rainfall. Field investigations and monitoring revealed that tectonic effects and stratigraphic lithology were the main reasons for the formation of the old landslide. The cutting of the slope and the damage to the anti-sliding piles at the toe of the landslide led to its reactivation, while continuous intense rainfall accelerated the deformation rate.

Summary: Landslides are highly frequent and devastating geological disasters worldwide, and early monitoring and warning are crucial. This study used InSAR technology to analyze Sentinel-1A SAR data and monitor the long-term surface deformation of the Cheyiping landslide in western Yunnan Province, China. The results showed a strong correlation between landslide movement and seasonal rainfall, with seasonal accelerated deformation. This case study contributes to the understanding of the slow deformation mechanism and early hazard warning of the Cheyiping landslide.
