Liquid nitrogen has shown excellent performances as a good fracturing medium in the extraction of unconventional natural gas,and its application in coalbed methane extraction is currently a research *** study focuses on the acoustic emission properties of coal specimens treated utilizing liquid nitrogen with varying initial temperatures in a three-point bending *** examination of the load-displacement curves of the considered coal samples,their mechanical properties are also revealed for different initial temperatures and cycling *** findings demonstrate a gradual decline in the maximum load capacity of coal rock as the temperature ***,when subjected to the same temperature,an escalation in the cycling frequency leads to a reduction in the peak load of coal *** suggests that both temperature and cycling frequency exert a notable impact on the fracturing efficacy of liquid ***-thaw cycling treatments and exposure to high-temperature conditions can activate preexisting damage in the coal rock,and,accordingly,influence its mechanical *** particular,throughout the progressive loading of coal rock samples,the failure mechanisms are predominantly characterized by the occurrence of tensile cracks,succeeded by the development,spread,and fracture of shear fissures.
