## 1 Introduction
presented a control system that combined grouting cable anchor reinforcement, bolt reinforcement, and roof cutting and pressure release. The number of coal pillars needed was decreased as a result of this combination strategy's successful management of the rock surrounding the roadway's displacement and deformation [14]. [PERSON] et al. used RocLab software (version 1.0) to determine the most effective roof cutting solution and then successfully applied it to Gaohe Coal Mine; peak roof settlement was considerably reduced [15]. A Mohr circle analysis model was created by [PERSON] et al. to investigate the stress evolution process. By examining stress evolution, they unveiled the fundamental causes of roadway deformation and subsequently suggested pertinent control strategies [16]. In accordance with key block theory, a mechanical model of the basic roof's fracture structure was made by [PERSON] et al., who also investigated the goat side's roof fracture process in situations including roof cutting and pressure release techniques [17]. [PERSON] et al. believed that the stress on the deep surrounding rock and the blasting effect are crucial factors contributing to rock bursts in deep mining areas; these factors are more important for controlling a hard roof [18]. [PERSON] et al. investigated the temporal system of roof-induced caving during continuous mining operations beneath a complex filling structure. In accordance with similarity theory, the data system was used to automatically collect and analyze stress and displacement changes with mining progress [19]. [PERSON] et al. proposed an induced roof caving method, in which a certain grasp of the space-time position of the induced roof caving was obtained. A variety of influencing factors of induced roof caving in goat were studied using catastrophe theory [20]. [PERSON] et al. developed a mechanical model to elucidate the relationship between bolt tensioning and the anchoring interface, established the axial force equation of the bolt drawing and anchoring interface, determined the shear stress distribution and load decreasing the law governing the transfer of force within the bolt anchoring section, and achieved successful management of the nearby rock in the hard roof area [21]. [PERSON] et al. studied and calculated the roof cutting parameters and seam connectivity rate of inclined coal seams; they advanced research on -roof cutting and pressure relief technology by introducing the idea and design process of the roof cutting connectivity rate [22]. After conducting a comprehensive analysis that took into account the economic feasibility and safety concerns related to the roof and floor of the roadway, the deep-hole pre-splitting blasting method was adopted to perform hard roof cutting and implement pressure-relief measures, ensuring efficient and safe mining operations in the hard roof area of the fully mechanized 1127 (1) working face at Guqiao Coal Mine. The following results were achieved: the tendency of the hard roof to cave was enhanced, enabling timely roof fall. This reduction in roof pressure mitigated its impact on the working face support, thereby ensuring roadway stability and facilitating smooth mining operations.
