Numerical modeling of coupled stress-fracture evolution in water-resisting key strata during longwall mining [PDF]
Scientific ReportsDuring underground coal mining, the evolution of stress and fracture development within the overlying water-resisting key strata (WRKS) significantly impacts its water-resisting properties, thereby making it a critical factor controlling the stability of

Failure and development height of overlying rock of a water flowing fracture in goaf under a karst aquifer [PDF]
Scientific ReportsThe factors leading to mine water inrush accidents are mainly sources of water, water channels, and intensity of water inrush. Mine water rush depends mostly on whether damage leads to the overlying strata of the working face penetrating the overlying ...

Adaptive filtering of microseismic data for monitoring a water-conducting fractured zone in a mine
Scientific Reports, 2022 AbstractWater-conducting fractured zones in a rock mass can cause problems in mining. Attempts have been made to monitor their development using microseismic signals. However, due to the lack of prior information, it is difficult to filter out mixed low-frequency interference with traditional denoising methods.
