###### Abstract
In terms of controlling the stability of the roof in deep mine roadways, [PERSON] et al. [15] transferred the mining stress of roadway roofs through roof-cutting and pressure-relief technology and derived a formula for calculating the height of the \"key layer\" for pressure relief. They also obtained the roof-cutting height, angle, and spacing between boreholes for cutting the \"key layer\". [PERSON] et al. [16] focused on supporting severely deformed soft rock roadways in deep mines. They proposed an NPR coupling support method suitable for roadways in the Mesozoic extremely soft rock coal-bearing strata of Xin'an Mine, which involves a coupling support design consisting of NPR anchor rods, steel strips, and bottom-angle grouting anchor rods. [PERSON] et al. [17] proposed the concept of high-pressure anchor injection grouting collaborative control for soft coal seams in kilometer-deep mine roadways, aiming to solve the problem of large deformation in these soft coal seams, and formed a collaborative control technology that combines high-prestressed anchor rods, anchor cable supports, high-pressure splitting grouting, and surface grouting modifications. [PERSON] et al. [18] used the Kouzidong mine goat roadway at the deep mine entrance as the engineering background and surmised that the mechanism of large deformation in the roadway is due to the significant rheological and strong expansion deformation of the surrounding rock after the plastic zone deteriorates under high-stress driving, which accelerates the deformation and instability of the roadway. They proposed a goat roadway support technology with \"high pre-stressed main support, grouting modified reinforcement, and strong roof support\" as the core. [PERSON] et al. [19] revealed the mechanism of top cutting and pressure relief in high-stress tunnels in deep mines. Taking the 121,302 working faces of Kouzidong Coal Mine as the engineering background, hydraulic fracturing top-cutting parameters were designed, and the effectiveness of top cutting and pressure relief was verified. [PERSON] et al. [20] conducted in-depth research on the pressure relief effect, surrounding rock stress evolution law, and control technology for deep goat cutting roadways to solve the problems of significant dynamic pressure and difficult support in deep goat retaining roadways. They constructed a collaborative control system for the surrounding rock of deep goat cutting roadways, which includes \"advanced roof cutting, constant resistance active pressure control of the roof, flexible and shrinkable displacement resistance to lateral pressure, high resistance temporary support resistance to dynamic pressure, and increased support length to protect the coal wall\". [PERSON] et al. [21] used the 3\({}^{-1}\)101 (3\({}^{-1}\) represents the coal seam number) working face of Hongqinghe Coal Mine as the engineering background to analyze the deformation mechanism of the surrounding rock of the high-stress roadways in deep mines. They proposed a directional tension blasting roof-cutting and pressure-relief technology for surrounding rock control in deep tunnels, and practical experience proved the scientific rationality of this technology. [PERSON] et al. [22] obtained a criterion for interlayer displacement based on the deformation characteristics of the top plate in deep well roof-cutting and retaining roadways, with the shear failure of the anchor rod as the critical indicator. In engineering practice, it is proposed that in order to improve the stability of the roadway roof during the retention period and control the deformation of the roof sinking, methods such as increasing the number of temporary support bodies in the roadway, improving the support stiffness, reducing the spacing between anchor rod supports, and increasing the pre-tightening force of anchor rods can be employed. In summary, GERRC is one of the technologies used to achieve safe and efficient mining in deep mines.
