###### Abstract
A comprehensive surrounding-rock management method of anchor-grit-cable-grouting coupled support to address the difficulties in supporting deep-well high-stress broken soft rock roadways is proposed, and the interaction mechanism between coupled support and surrounding rock is analyzed [6]. The composite support mode of'shotcrete + grouting bolt + anchor bolt + grouting cable + anchor cable' is put forward, and the rationality of the co-reinforcement technology of layer and double arch is verified [7]. Based on the instability mechanism of roadway, the control technology of high preload bolt + deep and shallow-hole crack filling is put forward, and this technology ensures the stability of the roadway surrounding rock by inhibiting the expansion of deep and shallow cracks and reinforcing the surrounding rock [8]. The composite failure mechanism of the surrounding rock of coal roadway based on the stress difference between deep and shallow anchor cables is revealed, and an anchoring and unloading coupled control technology is put forward [9]. Based on the aging characteristics of plastic zone expansion and the control effect of bolt support on plastic zone of surrounding rock, the control technology of surrounding rock stability is put forward [10]. A mechanical model of the lateral roof structure of the gob-side roadway is established, the mechanical state of the roadway support body at different mining stages is analyzed, and the dynamic instability mechanism of the support body caused by the fracture and sinking of the lateral basic roof is revealed [11]. The impact-damage mechanism of roadways in extra-thick coal seams is studied, the main influencing factors of top coal damage are revealed, and the anti-impact support technology of roadways in extra-thick coal seams is determined [12]. Taking the common problems of surrounding rock strength deterioration, stress environment deterioration, and structural instability and large deformation of surrounding rock in deep roadways as the starting point, the response mechanism of the crack evolution scale in the macroscopic surrounding rock damage process is discussed [13; 14]. The key concerns of experts and scholars on the butterfly failure theory are carried out in research, and the applicability of butterfly failure theory under different roadway cross-sectional shapes and layered surrounding rock conditions is analyzed [15]. The deformation and failure characteristics of the surrounding rock of rock-burst roadways and the main influencing factors are analyzed, and the selection principle of the support form of rock-burst roadways is proposed [16]. A mechanical model of full-length anchor bolt is established, and the stability of the mechanical bearing structure of the surrounding rock of high-stress soft rock roadways after full-length anchor bolts were anchored is studied [17]. The differential spatiotemporal evolution law of the number of cracks and development inflection points at different depths in the surrounding rocks of the two roadways is clarified, and the differential deformation mechanism of the surrounding rocks of the two roadways caused by the differences in stress state and crack development is revealed [18]. Uniaxial compression and true triaxial tests to address the problem of surrounding rock stability are conducted, the method of energy characterization and significance of rocks under uniaxial compression conditions is studied, and the temperature effect of granite cavern rock burst under true triaxial test conditions is explored [19; 20]. A new type of large deformation resistance-enhancing anchor cable is developed, and the developed new anchor cable to the actual roadway is applied successfully [21]. The maximum convergence deformation of the two sides is about 300 mm, and a good support effect is achieved.
