摘要:
为解决排土场-尾矿库联建系统稳定性问题，采用定性风险分析和数值模拟方法，以内蒙古某钼矿排土场-尾矿库联建工程为研究对象，研究联建系统整体稳定性及主要影响因素的影响。研究结果表明：尾矿库与排土场联建的主要风险因素为排土场堆高、渗流耦合和地震动力；通过Midas GTS NX软件构建数值模型计算分析发现，联建系统的最小主应力为8.89 MPa，最大主应力为9.41 MPa，模型应力分布较规律；联建系统整体安全系数1.54高于单独尾矿库和单独排土场安全系数，表明联建系统在提高工程稳定性方面具有一定优势；基于风险因素模拟分析，排土场堆高和地震载荷对联建系统安全影响较小，尾矿库渗流对排土场尾矿库联建系统的稳定性影响较大，当干滩长度d<50 m时，安全系数降至1.25，需加强管理。研究结果可为排土场-尾矿库联建系统的风险稳定性分析提供理论参考。
Abstract:
In order to address the stability problem of combined waste dump-tailings dam systems,qualitative risk analysis and numerical simulation methods are adopted,taking a combined waste dump-tailings dam project of a molybdenum mine in Inner Mongolia as the research object to investigate the overall stability of the combined system and the influence of the main controlling factors.The results show that the main risk factors of the combined tailings dam and waste dump system are waste dump stacking height,seepage coupling,and seismic loading.Numerical modeling and analysis using Midas GTS NX indicate that the minimum principal stress of the combined system is 8.89 MPa and the maximum principal stress is 9.41 MPa,with a relatively regular stress distribution in the model.The overall safety factor of the combined system is 1.54,which is higher than that of the stand-alone tailings dam and the stand-alone waste dump,indicating that the combined system has a certain advantage in improving engineering stability.Based on simulation analysis of the risk factors,the effects of waste dump stacking height and seismic loading on the safety of the combined system are relatively small; however,seepage in the tailings dam has a pronounced impact on the stability of the waste dump-tailings dam combined system.When the dry beach length d<50 m,the safety factor decreases to 1.25,and enhanced management is required.The research results can provide a theoretical reference for risk and stability analysis of combined waste dump-tailings dam systems.
