Abstract:In this paper, a series of optimization strategies are proposed to solve the problems of crushing zone treatment technology in underground mine backfill mining. Firstly, the process of backfill mining and the stability problems of the crushing zone frequently encountered in the implementation process were sorted out, and the shortcomings of the current solutions were analyzed. Secondly, based on theoretical analysis, the relevant mathematical model was constructed and the parameters were optimized to evaluate the effect of different treatment schemes. On this basis, combined with specific mine examples, the process and effect of optimization technology in practical application are discussed in detail. Finally, through the study of different filling materials and the discussion of measures to improve the stability of the crushing zone, this paper makes a comprehensive analysis of the technical optimization measures, including cost-effectiveness considerations, to ensure the feasibility and economy of the proposed optimization strategy. This study is of great significance for improving the efficiency and safety of underground mine backfill mining.
