ajst-20824	Zhang, Yuke	Numerical Simulation Study on The Ultimate Water Head of Artificial Dam in Coal Mine Underground Reservoir	2024	4	.pdf	application/pdf	2416	96	56	In order to solve the problem of the stability of the artificial dam of the underground reservoir, this paper takes the underground reservoir of the 51103 working face of Guojiawan Coal Mine as the engineering background, and uses the FLAC3D numerical simulation software to establish the artificial dam model, and the experimental results show that when the head height is 26m, the maximum tensile stress inside the dam is 1.264MPa, which is still lower than the limit of the tensile strength of the concrete, until the water pressure increases to 27m, the maximum tensile stress inside the dam is 1.290MPa, which is greater than the limit of the tensile strength of the concrete, so the ultimate head height of the artificial dam is 26m. Keywords: Underground reservoirs; artificial dams; numerical simulation. After reviewing the relevant literature, it is found that there are few studies on the stability of artificial dams in underground reservoirs, and the stability of concrete structures is mostly focused on the stability analysis of surface reservoir dams	cache/ajst-20824.pdf	txt/ajst-20824.txt
