In order to study the competition mechanism of particle migration and settlement behavior in the process of pipeline transportation of unclassified tailings paste slurry, Electrical Resistance Tomography (ERT) was used to carry out pipeline transportation tests on paste slurry with mass concentration of 60% and coarse particle content of 0, 5%, 10% and 15%, respectively. Based on the Maxwell equation, the conductivity-mass concentration mapping model was established. The plunger flow structure was reconstructed by the conductivity distribution, and the regression equation of the mass concentration and the coarse particle content in the plunger area was established. The results show that the conductivity and slurry mass concentration in the central area of the pipeline are higher than those in the side wall area, and the particle migration behavior forms a typical plunger flow structure. With the increase of coarse particle content, there are "optimal point" (4.3%) and "equilibrium point" (9.6%) of coarse particle content. When the content of coarse particles is 4.3%, the particle migration effect is the best, forming a stable particle structure flow of "fine particles carrying coarse particles". When the content of coarse particles exceeds 9.6%, the settlement effect begins to dominate, and the accumulation of particles at the bottom of the pipeline increases significantly. The ERT technology has successfully realized the dynamic visualization of the concentration field of paste pipeline transportation, revealed the dynamic balance law of particle migration-settlement, improved the stability of "plunger structure" and reduced the risk of plugging, which has a reference value for the safe transportation of paste filling.

为研究全尾砂膏体料浆管道输送过程中颗粒迁移规律与沉降行为的竞争机制,采用电阻层析成像技术(ERT),对质量浓度为60%、粗颗粒掺量分别为0、5%、10%、15%的膏体料浆开展管道输送试验。基于麦克斯韦方程建立电导率-质量浓度映射模型,通过电导率分布重构柱塞流结构,建立柱塞区质量浓度与粗颗粒掺量的回归方程。结果表明:管道中心区域的电导率与料浆质量浓度均高于边壁区域,颗粒迁移行为形成典型柱塞流结构,且随着粗颗粒掺量的增加,存在粗颗粒掺量“最优点”(4.3%)和“平衡点”(9.6%)。当粗颗粒掺量为4.3%时,颗粒迁移效果最优,形成“细颗粒承载、粗颗粒被载”的稳定颗粒结构流;当粗颗粒掺量超过9.6%后,沉降作用开始占据主导,管道底部颗粒堆积显著增加。ERT技术成功实现了膏体管输浓度场动态可视化,揭示了颗粒迁移-沉降的动态平衡规律,提升了“柱塞结构”稳定性并降低了堵管风险,对膏体充填安全输送具有参考价值。

为研究全尾砂膏体料浆管道输送过程中颗粒迁移规律与沉降行为的竞争机制,采用电阻层析成像技术(ERT),对质量浓度为60%、粗颗粒掺量分别为0、5%、10%、15%的膏体料浆开展管道输送试验。基于麦克斯韦方程建立电导率-质量浓度映射模型,通过电导率分布重构柱塞流结构,建立柱塞区质量浓度与粗颗粒掺量的回归方程。结果表明:管道中心区域的电导率与料浆质量浓度均高于边壁区域,颗粒迁移行为形成典型柱塞流结构,且随着粗颗粒掺量的增加,存在粗颗粒掺量“最优点”(4.3%)和“平衡点”(9.6%)。当粗颗粒掺量为4.3%时,颗粒迁移效果最优,形成“细颗粒承载、粗颗粒被载”的稳定颗粒结构流;当粗颗粒掺量超过9.6%后,沉降作用开始占据主导,管道底部颗粒堆积显著增加。ERT技术成功实现了膏体管输浓度场动态可视化,揭示了颗粒迁移-沉降的动态平衡规律,提升了“柱塞结构”稳定性并降低了堵管风险,对膏体充填安全输送具有参考价值。

In order to study the competition mechanism of particle migration and settlement behavior in the process of pipeline transportation of unclassified tailings paste slurry, Electrical Resistance Tomography (ERT) was used to carry out pipeline transportation tests on paste slurry with mass concentration of 60% and coarse particle content of 0, 5%, 10% and 15%, respectively. Based on the Maxwell equation, the conductivity-mass concentration mapping model was established. The plunger flow structure was reconstructed by the conductivity distribution, and the regression equation of the mass concentration and the coarse particle content in the plunger area was established. The results show that the conductivity and slurry mass concentration in the central area of the pipeline are higher than those in the side wall area, and the particle migration behavior forms a typical plunger flow structure. With the increase of coarse particle content, there are "optimal point" (4.3%) and "equilibrium point" (9.6%) of coarse particle content. When the content of coarse particles is 4.3%, the particle migration effect is the best, forming a stable particle structure flow of "fine particles carrying coarse particles". When the content of coarse particles exceeds 9.6%, the settlement effect begins to dominate, and the accumulation of particles at the bottom of the pipeline increases significantly. The ERT technology has successfully realized the dynamic visualization of the concentration field of paste pipeline transportation, revealed the dynamic balance law of particle migration-settlement, improved the stability of "plunger structure" and reduced the risk of plugging, which has a reference value for the safe transportation of paste filling.
