###### Abstract
The local instability problem caused by anchor fracture failure in deep roadways under impact dynamic loads is revealed, and the reinforcement support technology to reduce anchor fracture and improve the stability of roadway support body is explored [22]. Combining anchor support with grouting technology, an effective solution for deep soft rock and broken roadway surrounding rock control is provided [23; 24]. An intelligent real-time detection and positioning method for coal mine roadway support steel belt anchor hole based on deep learning model and depth camera is proposed, and the feasibility of this method in the unstructured environment of coal mine underground is verified [25]. Based on structural mechanics theory, the constraint stress in the plastic extrusion deformation zone of the anchor is regarded as a rectangular distribution mode, and the rationality of the model is verified by comparing the model calculation results with experimental data [26]. Taking the roadway of 10,607 gas extraction as the research object, the large deformation and damage phenomenon of roadways under dynamic pressure is studied, active and passive support technologies are proposed, the engineering application is carried out, and a good control effect of roadway surrounding rock is obtained [27]. The results of the tensile and shear tests of anchor cables are discussed. By establishing a mechanical model of the interaction between anchor cables and jointed rock mass, the failure mechanism of anchored jointed rock mass under tension and shear was revealed, providing a practical and convenient method for improving the shear strength of the anchor beam anchor cable system and enhancing the stability of the roadway [28]. The changing trends of the physical and mechanical properties of coal rock mass in the strong wind oxidation zone are revealed, the deformation and failure mechanism are analyzed, and a coupling support scheme of 'pre-grouting + anchor mesh shotcrete + inverted arch structure + U-shaped steel + high and low pressure, deep and shallow hole reinforcement grouting' based on the deformation and failure characteristics of the wind-oxidized surrounding rock roadway is proposed [29]. The failure mode of a steel tube-concrete structure is studied, and the elastic center method to obtain the internal force of the steel tube-concrete structure with cable is used. The results show that the cable can ensure that it has a high bearing capacity [30]. In view of the harsh environment of deep mechanized mining face and the seriously unbalanced distribution of driving, supporting, and anchoring time, a new type of highly adaptable advanced support of the mechanized mining roadway with strong adaptability, a large support strength, and a large working space is designed [31]. The problem of stability control of surrounding rock in deep soft rock roadways is explored, the mineral composition and microstructure of the surrounding rock is analyzed, the microscopic mechanism of roadway damage and the deformation and damage mechanism of soft rock cross-cutting roadways are obtained, and a high prestressed compensating support countermeasure based on constant resistance large deformation anchor bolts is proposed [32]. The problems of poor support effect and serious deformation and damage of surrounding rock in mining roadways under deep-mining stress are analyzed. Taking the upper roadway 2424 of Sun-cun Coal Mine as the background, the stress, deformation, and damage laws of surrounding rock in mining roadways under single support and multi-level support were compared and analyzed. It was found that multi-level support technology has obvious advantages. The key parameters of multi-level support were determined, and field industrial tests were carried out. The results show that the overall deformation of surrounding rock is significantly reduced after multi-level support [33].
