摘　　要：为研究超深井长距离膏体充填管道自流输送问题,根据云南某矿山实际充填管路采用Gambit建立三维数值模型,用ANSYS FLUENT软件进行数值模拟计算,以水平管道和弯管为例研究了不同配比、浓度和流量下的管道压力、流速变化规律和管道阻力损失之间的关系。通过井下工业环管的压力监测系统,统计分析矿山井下实际管道压力监测值,井下实际监测结果和采用ANSYS FLUENT软件三维数值模拟研究结果较为接近,表明ANSYS FLUENT软件模拟超深井长距离膏体充填管道输送是可行的,研究结果可为矿山实现超深井、长距离、大倍线条件下膏体充填管道输送提供技术支持。To study the problem of artesian transportation of long distance paste filling pipeline in ultra deep well,according to the actual filling pipeline in a mine in Yunnan Province,a three-dimensional numerical model was established by gambit,and the numerical simulation was carried out by ANSYS FLUENT software.Taking horizontal pipeline and elbow as examples,the relationships between the change rule of pipeline pressure and velocity and the loss of pipeline resistance under different proportion,concentration and flow rate were studied.Through the pressure monitoring system of the underground industrial ring network,the monitoring value of the actual underground pipeline pressure in the mine was statistically analyzed.The results of the actual underground monitoring were close to the three-dimensional numerical simulation results by using ANSYS FLUENT software,which shows that it is feasible to simulate the long-distance paste filling pipeline transportation in the ultra deep well by using ANSYS FLUENT software,and the research results can provide technical support for paste filling pipeline transportation to realize the ultra deep well,long-distance and large fold line for the mine.
