Taking a copper mine as the engineering background, optimization research on the parameters of stope mining drifts was carried out to realize the safe and efficient mining of horizontal pillars in underground mines and ensure the stability of stopes. Based on the structural mechanical model of simply supported beam, the law of tensile stress of drift roof varying with drift width was analyzed, and the drift width and reserved roof thickness were initially determined. Further, FLAC3D numerical simulation was used to compare the influence of drift width on the overall stability of stope under different reserved roof thicknesses. The results show that based on the structural mechanical model of simply supported beam, the optimized structural parameters of the drift are a reserved roof thickness of 2 m and a drift width of 4 m. Taking Scheme 3 (drift width of 3.5 m, drift height of 4 m) as an example, theoretical calculation shows that the maximum tensile stress of its roof is 0.37 MPa, and the safety coefficient reaches 1.86.In the numerical simulation, the maximum tensile stress is 0.49 MPa, the stope roof displacement is small, the roof basically does not undergo plastic failure, and the structure remains stable. The method combining the simply supported beam theory and numerical simulation can accurately predict the load changes and stress distribution in the mining of horizontal pillars, and provide a basis for the optimization of structural parameters of mining drift for similar mine projects.

为安全高效地回采地下矿山水平矿柱并确保采场稳定，以某铜矿为工程背景，进行采场回采进路参数优化研究。基于简支梁结构力学模型，分析进路顶板拉应力随进路宽度变化的规律，初步确定进路宽度与预留顶板厚度；进一步采用FLAC3D数值模拟，对比不同预留顶板厚度下进路宽度对采场整体稳定性的影响。结果表明：基于简支梁结构力学模型，优选进路结构参数为预留顶板厚度2 m、进路宽度4 m；以方案3（进路宽度3.5 m，进路高度4 m）为例，理论计算显示其顶板最大拉应力为0.37 MPa，安全系数为1.86，数值模拟中最大拉应力为0.49 MPa，采场顶板位移较小且顶板基本未发生塑性破坏，结构保持稳定。采用简支梁理论与数值模拟相结合的方法，能够准确预测水平矿柱回采中的荷载变化与应力分布，为类似矿山工程的回采进路结构参数优选提供依据。
