膏体充填料浆管道自流输送分析及管线布置

自流充填具有充填效率高、工艺流程简单等优势,但膏体充填料浆由于浓度高,管道输送阻力大,易发生堵管等输送风险,因此,膏体充填料浆自流充填难度大。为了使膏体充填料浆实现安全可靠的自流充填,简化充填工艺流程,节约充填成本,本文以探究膏体料浆自流充填的可行性、确定膏体充填料浆自流充填条件为研究目标,通过试验确定合理的充填工艺参数,从而制备了均质性较好的膏体充填料浆,计算了膏体充填料浆在管道输送中的阻力,论证了膏体充填料浆自流输送的可行性,确定了膏体自流充填最大允许倍线。并根据膏体充填料浆的基本参数,结合膏体料浆管道输送的特性及井下实际生产情况,优化了充填管道布置。经生产实践验证,膏体充填料浆的自流充填能力由原先的50m~3/h提高到了110m~3/h,且生产运行过程中,膏体充填料浆管道输送系统稳定可靠,料浆管道输送流畅,能够满足膏体充填料浆自流输送需求,极大提高了充填效率,简化了充填工艺流程。

Analysis of paste filling slurry pipeline gravity transportation and pipeline layout

In this paper, the suitable filling process parameters are determined and the homogeneous paste filling slurry is prepared. According to the basic parameters of paste filling slurry and the characteristics of paste slurry pipeline transportation, the resistance of paste filling slurry in pipeline transportation is analyzed and calculated; the maximum allowable line of self flow transmission of paste filling slurry pipeline is determined. Finally, according to the actual situation of mine production, the filling pipeline is arranged. After the production verification, the conveying system is stable and reliable, which can meet the needs of the paste filling slurry self flow transportation.
