Geostress field inversion and stress characterization of the Pan 'er Coal Mine in Huainan, China

To thoroughly elucidate the distribution patterns of in-situ stress within the Pan 'er Coal Mine in Huainan, China, this study systematically compiles and extensively analyzes existing test data. Utilizing advanced modeling and numerical simulation techniques via SolidWorks, ANSYS, SPSS, and FLAC3D, a precise three-dimensional spatial representation of the deep in-situ stress distribution within the mine is constructed. This comprehensive analysis unveils the intricate stress distribution characteristics of the in-situ stress field at the Pan 'er Coal Mine, thereby providing a robust scientific foundation for enhancing the safety and efficiency of coal resource extraction methodologies.
