rockburst. One is rockburst control technology based on stress release. The core idea is to weaken the mechanical properties of the rock itself, change the integrity of the local rock mass, and weaken the effect of the initial stress on the surrounding rock, so that the rock mass does not have the conditions for rockburst or weaken the strength of rockburst, such as drilling blasting boreholes and microwave fracturing, destress blasting, large-scale panel destressing, hydraulic fracturing in roof techniques to absorb energy and vibration waves [5; 6; 7; 8; 9; 10]. The other is the rockburst control technology based on energy absorption. The core idea is to curb the large deformation of the surrounding rock of the tunnel by means of support or filling, and to control the stability of the surrounding rock through the absorption and dissipation of energy. In the control of rockburst through the support system, [PERSON] et al. [11] considered the anchor rod as the main component--the main role was to reinforce the surrounding rock and the suspension, and emphasize the strength of the anchor rod to control the rockburst, including the supporting role of the net, belt and other auxiliary components. Since then, the bolt with energy absorption characteristics gradually appeared. As proposed by [PERSON] [12], a support system for rockburst control comprises surface-retaining devices and yield rockbolts as well as yield cable bolts when needed. [PERSON] et al. [13] explored the control mechanism of the constant-resistance energy-absorbing (CREA) bolt to rockburst. [PERSON] et al. [14] proposed the concept of NPR support for the first time and developed a constant resistance and large deformation bolt/cable with the above excellent properties based on the excellent properties of negative Poisson's ratio materials or structures in terms of impact resistance, shear resistance and energy absorption. In addition, [PERSON] and [PERSON] [15] made a quantitative estimation of rockburst based on the number of supporting devices such as energy-absorbing bolts required for scientific and sufficient support of pillars. In addition to the energy-absorbing anchor, [PERSON] et al. [16] developed a flexible protection network system suitable for tunnel rockburst disaster protection. [PERSON] et al. [17] proposed a metal retractable bracket and a flexible energy-absorbing cushion, which could also play a role in controlling rockburst disasters. In controlling rockburst by filling method, feasible mining techniques under rockburst conditions were put forward, that is, the stoping and filling method [18]. According to the characteristics and uses of stale waste filling materials, [PERSON] et al. [19] proposed two processes of volume filling and strength filling, and designed the key technology of stale garbage filling to control rockburst. However, rockburst control technologies represented by stress release had weakened the high-stress state of the surrounding rock to a certain extent, but they could not completely eliminate the stress at its root. It is necessary to resist the occurrence of rockburst after the redistribution of stress through the application of the support system. By applying the method of supporting or filling to increase the energy storage limit, the construction process would be increased, the progress of the project would be affected, and the overall cost of the project would be increased. The construction side of the project adopted the method of drilling pressure relief, but rockburst disasters still occurred from time to time, which could not solve the problem of rockbursts in tunnel construction. AE (acoustic emission) can be more effectively applied to warn of rockburst danger [20; 21; 22]. In the aspect of acoustic emission analysis, the existing research focuses on the time domain and frequency domain of acoustic emission, and then analyzes and understands rockburst [23]. However, the conclusions are mainly based on the characteristics of acoustic emission parameters of a certain experiment [24; 25; 26].
