Summary: Accurately predicting mining-induced subsidence is essential for sustainable mine management. The subsidence caused by the mining of Northern Upper Panels (NUP) and Southern Lower Panels (SLP) at the Barapukuria longwall coal mine was simulated using the Displacement Discontinuity Method. The effects of various factors, such as the ground surface, mining panels, faults, and the dyke, were considered in the numerical model. The predicted subsidence was compared with the observed subsidence, and the best match in terms of Young's modulus was determined. Future subsidence was also predicted, and vulnerable areas were identified based on tilt angle and extensile strain.

Summary: The exploitation of mineral resources is crucial for cost-effective construction but has also led to severe damage to the ecological environment in mining areas. This study focuses on effectively monitoring surface environmental problems in the Huinong coal mining subsidence area, Shizuishan city, Ningxia, China. Remote sensing techniques and classification methods were used to analyze the changes in the surface environment from 1979 to 2018. The results show significant changes in the coal mining subsidence area over the past 40 years.

Summary: Mining-induced subsidence leads to farmland damage and ponding formation. Traditional mining and reclamation (TMR) has low reclamation rate and long-term farmland abandonment. In this study, two critical width models were proposed to protect farmland and increase the reclamation rate. Concurrent mining and reclamation (CMR) and TMR were simulated, and the advantages of CMR were discussed. The results show that CMR can prolong farmland life, increase reclamation rate and farmland area, and has long-term social and ecological benefits.

Summary: The study demonstrates the use of the PS-InSAR technique for measuring surface subsidence caused by underground coal or mineral extraction. C-band data from Sentinel 1A/B sensors were analyzed to measure the deformation level. The results showed that the PS-InSAR technique is effective in detecting and monitoring subsidence in underground mines.

Summary: Coal mining can cause long-term ground subsidence, leading to environmental damage and other disasters. This study developed a prediction method for dynamic ground subsidence using a time function model and applied it to a specific mine, with good agreement between the simulated results and monitoring data. The dynamic development of the ground subsidence basin can assess underground losses and provide early warning of hazards.

Summary: Environmental monitoring of mining regions is crucial in preventing geohazards and ensuring sustainable exploitation. This study used satellite imagery and persistent scatterer interferometry (PSI) to monitor surface deformation in the Pabdana mining area over three time periods. The results showed a clear relationship between coal extraction progress and subsidence, with the subsidence rate varying temporally and spatially. The approach used in this study can be applied to other similar coal mining zones.

Summary: A modeling analysis of ecological urban landscape pattern evolution based on multisource remote sensing data was proposed to improve the development level of ecocity. Research on an ecotype city found that urbanization led to an increase in building land patches and a reduction in fragmentation, while cultivated land and green space decreased, resulting in a decline in ecological urban landscape diversity.

Summary: This study focuses on the subsidence characteristics and reclamation methods of the second coal mine in Zhaogu mining area caused by underground mining. The boundaries of submerged and damaged zones are identified using UAV monitoring. The subsidence basin shape is influenced by overburden composition, mining method, and mining sequence. The post-mining land is reclaimed for various purposes, including water reservoir, aquaculture, fishing, boating, afforested areas, board and lodging areas, and picking gardens.

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: The research aims to understand the movement laws of overlying strata above a fully mechanized coal mining face backfilled with gangue in order to address the issue of surface subsidence during coal mining. The study conducted at Jiulishan Coal Mine in China analyzed the deformation of backfilled gangue, surrounding rock stability, and key strata behavior. The findings suggest that increasing the strength of backfilled gangue can effectively control movement of overlying strata, leading to stable surface subsidence.
