ajst-7351	Guo, Xiaohui	Sandstone Impact Damage Study	2023	6	.pdf	application/pdf	2550	104	55	Bearing capacity curve Figure 5 shows the bearing capacity curves of the four ratios under the action of cyclic impact, and it can be seen from the figure that the specimens all went through four stages during the impact: compression-density stage, linear elastic deformation stage, microcrack expansion stage and damage stage. In conclusion, the study of coal seam damage by impact loading is necessary and can provide theoretical support for the study of the damage mechanism of coal seams.	cache/ajst-7351.pdf	txt/ajst-7351.txt
