During the process of coal mining, there is a violent appearance of mining stress when the initial weighting occurs. To guarantee the safety of the gob-side entry formed automatically by roof-cutting (EFARC) in an inclined coal seam, a study was conducted on the initial weighting mechanism and appearance characteristics through field monitoring and...

... In the mining of steeply dipping coal seams, due to the gravity dip effect, the roof strata not only move in the direction of vertical rock layers (similar to horizontal coal seam mining), but also move in the direction of parallel rock layers, resulting in a "temporal" and "asymmetric" deformation and failure process of the roof (Xie 2023;Xie et al. 2018;Wu 2024;Wang et al. 2015). Numerous scholars have adopted methods such as physical simulation experiments, theoretical analysis, numerical calculations, and on-site measurements to study the asymmetric deformation and failure motion laws of overlying strata with steeply dipping and high mining heights from different perspectives (Tu 2014;Xie et al. 2023a, b, c, d;Chai et al. 2019;Zhen et al. 2023), the distribution characteristics and distribution patterns of surrounding rock stress (Xie 2023;Luo et al. 2022a, b;Pang 2020), and the stability control mechanism of the "support surrounding rock" system (Xie 2021;Yang et al. 2020;Wang 2017;Xie et al. 2023a, b, c, d) Research and exploration have been carried out on the formation mechanism of surrounding rock disasters in working faces such as coal wall fragmentation Yang et al. 2019) and floor sliding , and targeted prevention and control measures have been proposed, which has promoted the continuous progress of theory and technology in mining steeply dipping coal seams and laid the foundation for further research. However, the spatial fracture evolution characteristics and fracture mechanism of overlying strata in steeply dipping and high mining areas are not yet clear. ...
