In order to understand the research progress of rockburst risk prevention technology in deep hard rock mines

the relevant literature was summarized. Firstly

a general idea of rockburst risk prevention was proposed from three perspectives: avoiding rockburst before the occurrence

reducing the hazard of rockburst during the incident

and evading the damage of rockburst afterwards. Then

the types of rockburst prevention technology were summarized based on this idea. Additionally

the connotation of each technology and its prevention mechanism were analyzed in detail. Finally

the future development direction of rockburst risk prevention technology was prospected. The results show that the rockburst risk prevention technologies for deep hard rock mines can be summarized into five aspects: mining design

stress relief technology

alteration of rock formation properties

rock mass support and personnel exposure. Among them

the mining design includes mining methods

stope parameters

pillar retention

mining sequence

recovery rate

and goaf treatment. Stress relief technology includes distress blasting

stress relief slots

stress relief tunnels

stress relief holes and stress relief fissures. Alteration of rock formation properties includes hydraulic fracturing

confined blasting and water injection softening. Rock mass support includes surface support

internal support and combined support. Personnel exposure includes re-entry protocol

remote equipment and personnel protection. In the future

the prevention guidelines of rockburst risk in deep hard rock mines can be established from the construction of prevention systems for different types and risk levels of rockburst

research of new technologies

and evaluation of prevention time and effect.
