Frontiers Surface Environmental Evolution Monitoring in Coal Mining
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. Therefore, it is particularly important to effectively monitor surface environmental problems in the mining subsidence area caused by the exploitation of mineral resources. Addressing the problem that traditional methods cannot reliably monitor surface subsidence in coal mining, a novel method has been developed for monitoring subsidence in mining areas using time series unmanned aerial vehicle (UAV) photogrammetry in combination with LiDAR.

New approach for the digital reconstruction of complex mine
Visualization of complex geological structures can technically support the accurate prediction and prevention of coal mine disasters. This study proposed a new digital reconstruction method to visualize geological structures based on establishing a virtual model in the digital twin system. This methodology for the digital reconstruction of The accuracy rate of identified coal fire areas at night time reaches as high as 92.78%, which is higher than that of daytime on 2nd October, 2016 and 5th October, 2016. In this research, the application of UAV-borne thermal imaging demonstrates a great potential to precisely and rapidly describe features of coal fires.Using high-resolution UAV-borne thermal infrared imagery to detect coal

MFPA-Net: An efficient deep learning network for automatic
1. Introduction. High-intensity underground coal mining activities cause surface movement and deformation, which can result in subsidence and fracture of the overlying rock layer, and eventually lead to surface collapse and formation of ground fissures (Hu and Wang, 2014).Those ground fissures can function as gas channels, transferring Surface subsidence caused by coal mining has become an important factor that affects and restricts the sustainable development of mining districts. It is necessary to use appropriate methods for effective subsidence monitoring.

The official photogrammetry definition is “the use of photography in surveying and mapping to ascertain measurements between objects”. Put simply, it’s the science of obtaining measurements from photographs.
