In order to study the influences of diameter, length and installation position of tapered pipeline on the ratio of full pipe flow in gravity-fed pipeline transport of backfill slurry, a small-scale loop pipe test was carried out by using independently developed tapered pipeline. The hydraulic slope and ratio of full pipe flow were tested for gravity-fed transport of slurry via tapered pipeline, and Pearson correlation analysis was also conducted to explore the influence of various factors on the ratio of full pipe flow. The results show that the ratio of full pipe flow significantly presents a negative correlation to the diameter of tapered pipeline, which increases exponentially with the reduction in the diameter of tapered pipeline. The ratio of full pipe flow increases sharply for a pipe with diameter less than 50 mm. Furthermore, the ratio of full pipe flow presents a positive correlation to the length of tapered pipeline, which increases linearly with the increased length of tapered pipeline. However, the installation position of tapered pipeline in horizontal section of pipe has little effect on the ratio of full pipe flow, which can be negligible.

为研究变径管管径、长度和安装位置对料浆自流输送满管率的影响规律,自主设计研发了一套小型变径环管试验装置,测试不同变径管条件下料浆自流输送的水力坡度及满管率,并利用皮尔森相关分析法探究各因素对满管率的影响程度。结果表明,满管率与变径管管径存在极显著负相关关系,随着管径减小呈指数型增长,管径小于50 mm时满管率急剧增长;满管率与变径管长度存在显著正相关关系,随着长度增加呈线性增长;变径管在水平管段安装位置的变化对满管率影响很小,可忽略。

为研究变径管管径、长度和安装位置对料浆自流输送满管率的影响规律,自主设计研发了一套小型变径环管试验装置,测试不同变径管条件下料浆自流输送的水力坡度及满管率,并利用皮尔森相关分析法探究各因素对满管率的影响程度。结果表明,满管率与变径管管径存在极显著负相关关系,随着管径减小呈指数型增长,管径小于50 mm时满管率急剧增长;满管率与变径管长度存在显著正相关关系,随着长度增加呈线性增长;变径管在水平管段安装位置的变化对满管率影响很小,可忽略。

In order to study the influences of diameter, length and installation position of tapered pipeline on the ratio of full pipe flow in gravity-fed pipeline transport of backfill slurry, a small-scale loop pipe test was carried out by using independently developed tapered pipeline. The hydraulic slope and ratio of full pipe flow were tested for gravity-fed transport of slurry via tapered pipeline, and Pearson correlation analysis was also conducted to explore the influence of various factors on the ratio of full pipe flow. The results show that the ratio of full pipe flow significantly presents a negative correlation to the diameter of tapered pipeline, which increases exponentially with the reduction in the diameter of tapered pipeline. The ratio of full pipe flow increases sharply for a pipe with diameter less than 50 mm. Furthermore, the ratio of full pipe flow presents a positive correlation to the length of tapered pipeline, which increases linearly with the increased length of tapered pipeline. However, the installation position of tapered pipeline in horizontal section of pipe has little effect on the ratio of full pipe flow, which can be negligible.
