Based on the occurrence characteristics of the soft, fractured, and thick large orebodies in a gold mine, the mechanized upward drift filling mining method was recommended. Six sets of stope structural parameters were designed through an orthogonal experiment, and the FLAC3D numerical simulation software was utilized to analyse the stope stability. The simulation results indicate that the compressive and tensile stresses in the stope are mainly concentrated at the top and bottom corners of the sidewalls, and both exhibit a symmetrical distribution. The displacement values of the stope roof, floor, and hanging wall surrounding rock increase with the increase of the drift width and drift height, but the overall displacement values are relatively small. On the premise of ensuring the safety and stability of the stope, larger stope structural parameters are preferentially selected to improve the technical and economic indicators. Therefore, Scheme 3 (with both the drift width and drift height being 5 m) is determined as the optimal stope layout scheme. The field application results indicate that when the mechanized upward drift filling mining method is adopted for extraction, the stope production capacity reaches 220 t/d, and the development and cutting ratio is 24.5 m3/kt. Furthermore, the ore loss rate is 6.2%, and the dilution rate is 8.3%, achieving favourable technical and economic benefits.

针对某金矿软弱破碎厚大矿体的赋存特征,推荐采用机械化上向进路充填采矿法。通过正交试验设置了6组采场结构参数,采用FLAC3D数值模拟软件分析采场稳定性。模拟结果表明,采场所受压应力与拉应力主要集中在采场边帮顶底角位置,且均呈对称分布;采场顶底板和上盘围岩位移值均随进路宽度和进路高度增加而增大,但整体位移值均较小。在确保采场安全稳定的前提下,优先选择较大的回采结构参数,以提高采场技术经济指标,确定方案三(进路宽度、进路高度均为5 m)为最优采场布置方案。现场应用结果表明,采用机械化上向进路充填采矿法进行开采,采场生产能力达220 t/d、采切比为24.5 m3/kt,矿石损失率为6.2%、贫化率为8.3%,取得了良好的技术经济效益。
