摘要:
矿井灌浆管路系统是一个相对封闭的空间,浆液在流动过程中对管道的压力分布情况却难以掌握。因此,首先建立了一种浆液管道流动的数值计算模型,对其进行网格划分、边界条件设定和数值模拟计算流程,并对所建立的模型进行数值计算,得到浆液在管道中的变化特性; 其次,针对静压灌浆和动压灌浆2种不同的方式对管道造成的影响程度,利用ANSYS FLUENT12.1分别对这2种不同方式时的压力场进行模拟,对比静压与动压灌浆时的管道压力分布特点和分析浆液在管道中流动过程的压力损失等情况,该模型可以较好的预测静压灌浆和动压灌浆时的管路中的压力分布状态,有助于分析管路输送过程中不同管路位置的压力变化及分布规律,模拟结果显示利用动压进行灌浆作业,可以起到显著的增压效果; 最后,通过对比数值模拟计算和工业现场试验监测得到的数据,分析得出两者数据基本吻合。对比结果分析表明:该数值模型建立合理,对矿井远距离灌浆工作具有一定的指导价值。
Abstract:
Mine grouting pipeline system is a relatively closed space,slurry pipeline flow process pressure distribution is difficult to grasp.So,in the first,established a numerical model of the flow in the slurry pipeline,then to mesh,boundary conditions and numerical simulation process.The established model is numerically calculated to obtain a slurry characteristic changes in the pipeline; Secondly,according to the influence of the static pressure and dynamic pressure grouting,using the software of ANSYS FLUENT12.1,simulation of the pressure field,comparison of the pipe pressure distributionwith static and dynamic pressure and pressure loss characteristics analysis are carried out.The model can predict the pipe pressure distribution state when static and dynamic pressure grouting,which can help to analyze transport conduit pressure changes and distribution of the different positions of the pipeline,the simulation results show that:use of the dynamic pressure grouting operations can play a significant booster effect; Finally,a comparison of the data of numerical simulation and industrial field tests shows the both data are consistent.Comparative analysis of the results showed that:the numerical model is reasonable with a guiding value for the remote mine grouting work.
