This article focuses on the study of heat and mass transfer (HMT) fluid flow over an exponentially accelerated vertical plate, which is subjected to an applied magnetic field and viscous dissipation. The research has applications in various manufacturing processes such as wire/fiber drawing, hot rolling, continuous casting, and hot extrusion, where heat transfer to the ambient medium and the hot moving material are of utmost importance. The findings could also be relevant to aerospace engineering applications. The study investigates the time‐fractional natural convection phenomenon and utilizes conservation laws to derive the flow guiding equations, which are then made nondimensional. Finite difference discretization is utilized to solve the dimensionless equations implicitly. Then the flow simulation results such as concentration, temperature, and velocity profiles are discussed based on the variation in parameters such as Prandtl number (), thermal/mass Grashof number (), Eckert number (), magnetic parameter (), time‐fractional order (), and Schmidt number . Also, the HMT rate is depicted using the Nusselt number and skin friction plots. It is noted that HMT increases when increases and decreases. The change in time‐fractional order affects the velocity profiles adjacent to the wall and is more significant in the case of lower values of the Prandtl number.

The safety of mines is a top priority in the mining industry, and a precise assessment of aquifer water levels is crucial for conducting a risk analysis of water-related disasters. Among them, the GIS-based water abundance index method is widely used in water-richness evaluation. However, the existing research lacks sufficient determination of evaluation indicator weights, specifically in the following aspects: (1) failure to consider the information differences between indicators and (2) inadequate differentiation of the relative importance of each indicator and their importance to the evaluation target. Taking the No.3 coal roof of Dananhu No.7 coal mine as the research object, six factors are selected as the main indexes for evaluating water richness. The weights were calculated using an improved entropy method and the scatter degree method, with the principle of information entropy used to reconcile the competitive and consistent relationship between the two evaluation methods. This approach resulted in the determination of combination weights for each influencing factor, highlighting the information differences between indicators and the importance of each indicator. Finally, the evaluation of aquifer water richness is partitioned by combining the GIS analysis function. The findings suggest that the Ⅰ division has low water richness, while the Ⅱ division is primarily medium-to-high water rich. The accuracy of the evaluation results exceeds 80%, providing valuable insights for hydrophobic programs for other coal-seam roofs.
