Degradation of Confined Compressibility in Weakly Cemented Coal Gangue Backfill Exposed to High Humidity

Ruofan Wang, Yujie Zhu, Lang Liu, Junjun Yang et autres

Coal gangue (CG) backfill, utilizing magnesium slag as a cost-effective alternative to ordinary Portland cement, represents a critical technology for underground waste management in China. Crucially, the confined compressibility of this matrix governs its long-term deformation resistance. However, since CG is enriched …

Optimization of alcohol varnish coating processes for violin soundboards based on acoustic properties: combining the entropy method and Box-Behnken design response surface method

Jing Zhou, Lan He, Ruofan Wang, Siyuan Wang et autres

The surface coating of a violin is a complex, multi-layer varnishing process comprising dozens of layers. While providing aesthetics and protection, varnish coatings alter the wood's material properties and thus affect acoustic properties, with layer count being a key factor. However, the …

Exploration of integrated “excavation-backfill-retention” technical path and evolution law of mining-induced stress

Lang LIU, Wei HE, Shuangming WANG, Huisheng Qu et autres

Pillarless mining is a key research direction that has been continuously tackled in China’s coal mining field. Innovative achievements represented by gob-side entry retaining, “110/N00” mining methods, and backfill gob-side entry retaining (“111” mining method) have significantly promoted the development of this …

Neutrophil-associated plasma proteomics identifies HDAC1 as a baseline biomarker of immune tolerance during immunosuppressant withdrawal after pediatric liver transplantation: a single-center cohort study

Ruofan Wang, Tianran Chen, Guang Li, Weiping Zheng et autres

Background: In pediatric liver transplantation (pLT), long-term immunosuppression (IS) contributes to infection risk and chronic toxicity, yet IS minimization or withdrawal requires balancing rejection risk. Practical biomarkers for baseline risk stratification at the start of planned withdrawal remain scarce. This study investigated …

Assessing ground stability of a vertical backfilled stope considering creep behaviors of surrounding rocks

Ruofan Wang, Lang Liu, Mengbo Zhu, Huafu Qiu et autres

Backfill is often employed in mining operations for ground support, with its positive impact on ground stability acknowledged in many underground mines. However, existing studies have predominantly focused only on the stress development within the backfill material, leaving the influence of stope …
