EXPERIMENTAL OBSERVATION ON ROCK DAMAGE UNDER MICROWAVE THERMAL SHOCK

ABSTRACT
Microwave thermal shock is an optimized means of crushing rocks in engineering, in order to investigate the effect of microwave thermal shock on granite, this paper adopts microwave irradiation and SEM experiments to investigate the mechanical behavior and microstructural evolution law of granite, and the main conclusions are: With the increase of the duration of thermal shock, granite exhibits the law of linear increase, and the peak strength and elastic modulus show the trend of rising first and then decreasing; After thermal shock the acoustic emission signal of granite is linearly rising, while the internal shear cracks expand to form larger transgranular cracks, the results of the study have great significance for the future development of traditional mining technology.
