ajst-28615	Zhou, Yangyang; Wang, Wen	Study on Acoustic Emission Characteristics and Crack Evolution Characteristics of Conglomerate Under Uniaxial Compression	2024	15	.pdf	application/pdf	8226	286	47	zyy1050885023@163.com Abstract: Taking the giant thick conglomerate in Yima mining area as the research background, this paper investigates the acoustic emission characteristics and crack evolution law of conglomerate with different grain sizes under loading conditions through uniaxial compression test and acoustic emission (AE) technology, and discusses the influence of grain size on its damage mechanism and damage evolution. Kang et al[4] conducted high-temperature treatment on granites with different grain sizes, and found that the weakening of the heated granite is more serious with the increase of the grain size; Sabi et al[5] Brazilian splitting experiments, indicating that coarse-grained granite produces more cracks, and with the increase in grain size to induce the production of tensile cracks, the number of shear cracks also increased; Deng et al[6] three-point bending experiments on four different grain sizes of granite, found that with the increase in grain size, the peak load, fracture toughness value, the ratio of yield limit and peak load are reduced, the amount of deformation occurred in the damage increases The non-homogeneity of the specimens is more obvious; Zhao et al[7] investigated the role of particle size in controlling the permeability of sedimentary rocks through core size analysis and extraction of logging geologic parameters, and established a model for calculating the particle size and permeability, which revealed its non- homogeneity characteristics.	cache/ajst-28615.pdf	txt/ajst-28615.txt
