Macroscopic and microscopic mechanical behavior and seepage characteristics of coal under hydro-mechanical coupling

Journal of Central South University 2024年第8期31卷 2765-2779页

作者： gao, Ming-zhong gao, zheng Yang, Ben-gao Xie, Jing Wang, Ming-yao Hao, Hai-chun Wu, Yan Zhou, Lang Wang, Jing-yu State Key Laboratory of Intelligent Construction and Healthy Operation and Maintenance of Deep Underground Engineering College of Civil and Transportation Engineering Shenzhen University Shenzhen China State Key Laboratory of Intelligent Construction and Healthy Operation and Maintenance of Deep Underground Engineering College of Water Resource & Hydropower Sichuan University Chengdu China State Key Laboratory of Coal Mining and Clean Utilization Beijing China China Railway Engineering Equipment Group Co. Ltd. Zhengzhou China Northwest Engineering Corporation Limited Xi’an China

Understanding the physical, mechanical behavior, and seepage characteristics of coal under hydro-mechanical coupling holds significant importance for ensuring the stability of surrounding rock formations and preventing gas outbursts. Scanning electron microscopy, uniaxial tests, and triaxial tests were conducted to comprehensively analyze the macroscopic and microscopic physical and mechanical characteristics of coal under different soaking times. Moreover, by restoring the stress path and water injection conditions of the protective layer indoors, we explored the coal mining dynamic behavior and the evolution of permeability. The results show that water causes the micro-surface of coal to peel off and cracks to expand and develop. With the increase of soaking time, the uniaxial and triaxial strengths were gradually decreased with nonlinear trend, and decreased by 63.31% and 30.95% after soaking for 240 h, respectively. Under different water injection pressure conditions, coal permeability undergoes three stages during the mining loading process and ultimately increases to higher values. The peak stress of coal, the deviatoric stress and strain at the permeability surge point all decrease with increasing water injection pressure. The results of this research can help improve the understanding of the coal mechanical properties and seepage evolution law under hydro-mechanical coupling.

Background:Ischemia-reperfusion injury(IRI)poses a significant challenge to liver transplantation(LT).The underlying mechanism primarily involves overactivation of the immune *** shock protein 110(HSP110)functions as a molecular chaperone that helps stabilize protein ***:An IRI model was established by performing LT on Sprague-Dawley rats,and HSP110 was silenced using ***-eosin staining,TUNEL,immunohistochemistry,ELISA and liver enzyme analysis were performed to assess IRI following *** blotting and quantitative reverse transcription-polymerase chain reaction were conducted to investigate the pertinent molecular ***:Our findings revealed a significant increase in the expression of HSP110 at both the mRNA and protein levels in the rat liver following LT(P<0.05).However,when rats were injected with siRNAHSP110,IRI subsequent to LT was notably reduced(P<0.05).Additionally,the levels of liver enzymes and inflammatory chemokines in rat serum were significantly reduced(P<0.05).Silencing HSP110 with siRNA resulted in a marked decrease in M1-type polarization of Kupffer cells in the liver and downregulated the NF-κB pathway in the liver(P<0.05).Conclusions:HSP110 in the liver promotes IRI after LT in rats by activating the NF-κB pathway and inducing M1-type polarization of Kupffer *** HSP110 to prevent IRI after LT may represent a promising new approach for the treatment of LT-associated IRI.
