摘要: 目的 为了解决巷道围岩严重变形问题,基于组合赋权法和响应面法对巷道围岩钻孔卸压参数进行优化研究。 方法 针对李村煤矿巷道两帮围岩钻孔卸压参数优选问题,结合现场实际工程地质条件,采用Box-Behnken方法设计25组试验方案。应用FLAC3D进行数值模拟分析,获得不同参数条件下的力学响应特征,结合技术经济要求,选取施工成本、两帮移近量、顶底板移近量、最大垂直应力、塑性区面积、施工效率等6个指标,利用层次分析法和主成分分析法组合赋权各评价指标。 结果 提出巷道围岩钻孔卸压参数综合评价模型,克服评价指标单一、主观因素干扰等缺陷,形成系统、准确的评价方法。以规范化综合评分为响应指标、钻孔卸压参数为变量,构建多元二阶回归预测方程。巷道围岩钻孔卸压优化参数为:孔径0.1 m,孔深4 m,间排距1 m×1 m,此时综合效益最佳。 结论 提出的回归预测模型选取的钻孔卸压参数合理可行,降低围岩变形量的同时保证了经济效益,可为相关巷道围岩控制方案设计提供借鉴。

Abstract: Objectives With increasing mining depth, deformation of tunnel surrounding rock due to high stress has become increasingly serious. This study aims to optimize borehole stress relief parameters for the sidewalls of the Licun Coal Mine roadway. Methods Based on actual engineering geological conditions, 25 experimental schemes were designed using the Box-Behnken method. Numerical simulations using FLAC3D were performed to analyze the mechanical responses under different parameter combinations. Six evaluation indicators were selected based on technical and economic considerations:  construction cost, convergence of the sidewalls, roof-to-floor convergence, maximum vertical stress, plastic zone area, and construction efficiency. The analytic hierarchy process (AHP) and principal component analysis (PCA) were employed to determine the weights of each evaluation indicator. Results A comprehensive evaluation model for borehole stress relief parameters was established, overcoming limitations of single evaluation criteria and subjective bias, providing a systematic and accurate evaluation methodology. A multivariate second-order regression equation was developed, using normalized comprehensive scores as the response variable and borehole stress relief parameters as independent variables. The optimized borehole stress relief parameters were found to be: borehole diameter 0.1 m, depth 4 m, and spacing 1 m×1 m, achieving the greatest overall benefit. Conclusions The proposed model provides reasonable and feasible borehole stress relief para-meters, effectively controlling surrounding rock deformation while ensuring economic efficiency, and can serve as a reference for roadway surrounding rock control design.
