###### Abstract  
The effectiveness of grouting management is closely linked to the safety of mining operations, making the scientific and accurate evaluation of mine water hazard grouting management a critical issue that demands immediate attention. Current evaluation technologies for grouting effectiveness are limited by singularity in indicator assignment, reliance on isolated indicators, and the generalization of weak metrics. Using the top and bottom grouting project of the 110504 working face at the Banji coal mine in Anhui Province as a case study, both theoretical and practical insights were integrated. Drilling fluid consumption, final grouting pressure, water permeability, and dry material per unit length were selected as key indicators to establish a comprehensive grouting effect evaluation index system. To address the limitations of previous assignment methods, this study proposes a novel approach that combines the Precedence Chart (PC) with the Criteria Importance Through Intercriteria Correlation (CRITC) method. This integrated approach resolves the issues of singularity and subjectivity in prior assignment techniques. The evaluation system was constructed based on a single indicator framework, incorporating a comprehensive evaluation model that uses the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for ranking and the Rank Sum Ratio (RSR) for classification support. The model demonstrates a high goodness-of-fit, with a value of 0.938, indicating strong performance. The model's results were visualized in the form of a grouting effect zoning map, further validated through comparisons with actual on-site water discharge data and exploration borehole water inflow measurements. A maximum recorded influx of 70 m\({}^{3}\)/h, aligning with the relatively weak grouting zones identified in the evaluation. The findings demonstrate that the proposed model exhibits a high degree of reliability and scientific rigor, providing valuable theoretical guidance for enhancing coal body stability and minimizing coal loss. p 2024 1 10228. 10.3390/2024 10228. 10.  
efficacy and mine safety, it is imperative to develop a scientific and precise method for evaluating the effectiveness of grouting in managing mine water hazards. Establishing a comprehensive and systematic evaluation framework enables the objective assessment of post-grouting conditions, providing critical scientific insights for subsequent water hazard management decisions. This approach enhances the relevance and efficiency of mine water management strategies, reduces the risks associated with water ingress, and ensures the ongoing safety of coal mining operations. Furthermore, a thorough evaluation of grouting performance can help identify existing issues and shortcomings in current grouting practices, guiding future improvements and innovations in the technology. By comparing different grouting methods, the optimal approach can be identified, fostering continuous advancement in grouting techniques. Effective grouting management of mine water hazards can significantly reduce water inflow, lower drainage costs, improve coal resource recovery rates, and thereby enhance the economic performance of mining enterprises. Additionally, successful water damage control safeguards miners' safety and mitigates environmental pollution, yielding substantial social benefits. Mine water management is not only a significant concern in local contexts but also holds great importance on an international scale. Across the globe, many countries are grappling with the challenges posed by mine water. In some regions, extensive mining activities have led to complex issues related to mine water management. For instance, in countries with a long history of mining, such as Australia and Canada, efforts have been made to develop advanced technologies and strategies to address the problem of mine water contamination and ensure sustainable mining practices.
