To address the problems of flow velocity runaway and wear risk caused by high potential energy in slurry filling pipelines of ultra-deep mines, the ANSYS numerical simulation method was employed to systematically reveal the influence mechanisms of coarse aggregate type, mass concentration, flow velocity, and pipeline geometric parameters on pipeline wear. An innovative two-stage pressure regulation and wear reduction technology was proposed. The results indicate that the coarse aggregate type has a limited effect on the pipeline wear rate, with the water-quenched slag-based slurry exhibiting the lowest wear rate. The slurry mass concentration is significantly negatively correlated with the pipeline wear rate, whereas the slurry flow velocity is linearly positively correlated with the pipeline wear rate. Among the pipeline geometric parameters, the bending angle and inclination angle exert significant effects on pipeline wear, with the most severe wear occurring at the bend sections. In response, horizontal turn-back loop pipes and electric pressure regulating valves are installed at the middle and lower sections of the pipeline to regulate the slurry flow velocity in stages within the range of 0.8-3.1 m/s. Supplemented by a T-shaped buffer structure to optimize the flow pattern, this technology substantially reduces pipeline wear and system pressure fluctuations. It can reduce the wear rate of critical 90° bends by 82% compared to the pre-modification level, reduce the system pressure fluctuation amplitude by approximately 40%, decrease the incidence of slurry leakage accidents by 30%, and enhance the system operational efficiency by 25%. The research results can provide key technical support for deep mineral resource development.

针对超深井料浆充填管道高势能引发的流速失控与磨损风险问题，采用ANSYS数值模拟方法，系统揭示了料浆粗骨料类型、质量浓度、流速及管道几何参数对管道磨损的影响机制，创新性地提出了两级调压减磨技术。结果表明：粗骨料类型对管道磨损率影响有限，水淬渣基料浆磨损率最低；料浆质量浓度与管道磨损率呈显著负相关，料浆流速与管道磨损率呈线性正相关；管道几何参数中弯曲角度、倾斜角度对管道磨损影响显著，弯管处的磨损最为严重。对此，在管道中下部增设水平折返环管与电动调压阀，分阶段将料浆流速调控至0.8~3.1 m/s范围内，辅以丁字形缓冲结构优化流态，大幅降低管道磨损与系统压力波动，可使关键90°弯管磨损速率较改造前降低82%，系统压力波动幅度降低约40%，漏浆事故发生率下降30%，系统运行效率提升25%。研究结果可为深部矿产资源开发提供关键技术支撑。
