Investigating mining-induced disasters using earth observation time series data in the coal mines of Talcher region, Odisha

Abstract

Abstract The coal mining industry plays a pivotal role in powering the global energy demand, but it is not without environmental consequences. One of the significant environmental challenges associated with coal mining is mining-induced subsidence, which can result in ground deformation, land surface displacement, and infrastructure damage. This study focuses on investigating mining-induced subsidence in the Talcher region of Odisha, India, a prominent coal mining area, using earth observation time series data. The research leverages state-of-the-art satellite imagery and remote sensing techniques to monitor and analyze the subsidence patterns and trends in the Talcher coal mines. Over time, mining activities in the region have led to ground deformation and surface displacement, impacting the local environment and communities. This study utilizes a comprehensive time series of satellite data, including synthetic aperture radar (SAR) and optical imagery, to track subsidence and land surface changes. The objectives of this investigation include identifying areas susceptible to subsidence, quantifying the magnitude and rate of ground movement, and assessing the potential impact on local infrastructure and ecosystems. By utilizing earth observation data, it becomes possible to gain a deeper understanding of the dynamics of subsidence in the coal mining areas. The findings of this study are valuable not only for understanding the environmental repercussions of mining in the Talcher region but also for developing mitigation strategies and land-use planning to minimize the impact on local communities and the environment. This research contributes to the growing body of knowledge on mining-induced subsidence and provides insights into how earth observation data can be used to monitor and manage the consequences of coal mining in similar regions. Ultimately, the results of this study may inform policy decisions and sustainable mining practices to strike a balance between energy production and environmental conservation.
