Research on Filling Effect Determination of Solid Filling Working Face in Coal Mine Based on Multi-Criteria Decision Analysis

The solid backfilling operation in coal mines constitutes a pivotal component of the coal industry, playing a crucial role in ensuring miner safety, enhancing coal extraction efficiency, and preserving ecological integrity. However, the determination of the efficacy of backfilling measures represents a pressing concern in the present context. Multiple Criteria Decision Analysis (MCDA) stands as a quantitative analytical approach tailored to address complex decision problems, capable of synthesizing diverse factors to furnish a scientific basis for decision-making. This paper endeavors to delve into the assessment of solid backfilling effectiveness in coal mine working faces using MCDA, with the aim of providing theoretical insight and practical guidance for pertinent domains.
