Grouting technology is crucial for controlling rock deformation and ensuring stability in underground engineering. In this study, the grouting simulation experiments were implemented using superfine cement (SC) a water-soluble modified resin (MR) as slurries to evaluate anti-seepage effect of broken coal. The nuclear magnetic resonance (NMR) conducted analyze pore structures various grouted specimens. accordance with NMR results, multifractal characteristics types within specimens identified geometric fractal method. results showed that dimension Ds, based on seepage pore, ranged between 2 3, accompanied by high R2 values, effectively reflecting structure distribution characteristics. Specifically, Ds values MR specimen are closer porosity SC 2.12 times greater than specimens, indicating superior efficacy material. Moreover, uniaxial compressive demonstrate mechanical strength strain capacity exceed those This finding implies lower denser contribute enhanced homogeneity coal, thereby bolstering overall structural integrity. Therefore, NMR-based method can be regarded scientific feasible approach evaluating coal actual

Published: July 31, 2024

In the hot press process of high-performance bamboo-based fiber composites, there is a highly nonlinear relationship between production parameters and quality finished boards. Consequently, it challenging to accurately predict boards based on given parameters, equally difficult preset achieve desired board quality. The current approach relies manual experience, which may result in subpar material waste. To address these issues, this paper proposes bi-directional prediction model cHGWO-SCA-SVR, using collaboration-based hybrid GWO-SCA optimizer optimize relevant SVR, then predicting both directions. Finally cHGWO-SCA-SVR achieves an average R2 0.9591 for forward lower MAE MSE values compared other models; reverse model, attains 0.9553 models. results demonstrate superiority comparison with existing models, proving its significance guiding composites by compression.
