Abstract: Abstract: Along with the exploitation of deep mineral resources and the subsequent high concentration of ground stress, the frequent rock bursts occurrence increases consequently, which strongly hinder the safe and economic recovery of deep-seated mineral resources. Due to this greater mining depth followed by the occurrence of rockbursts problem, the application of destress blasting is recently growing as a deep mine safety tool. Destress blasting is one of the essential techniques to control the rockburst hazards in deep mines through the principle of stress transfer. As the main objectives, this paper reviews and discusses the meaning, brief history, and the application, classification, mechanism, influencing factors and Suitable areas for the application of destress blasting, and the possible challenges which may arise during its field application. As the application of destress blasting involves the use of explosives to fracture rocks as a kind of functional blasting, therefore, the destress blasting mechanism, was objectively discussed in this paper, and a certain understanding and ideas for further improvement of the field application of destress blasting technique was gained from this review. It is concluded that, the high stresses concentration in surrounding rock mass of the underground mining working face are decreased after the application of destress blasting.
