摘　　要：注浆流量监测是覆岩离层注浆巩固地表工程的重要内容之一。利用光栅计量技术实现对液固两相流体浓度的测定,并应用可编程控制器PLC进行编程,控制整个监测过程。光栅测量系统误差估计为-0.083%^+0.248%,降低了注浆流量监测的成本,实现了监测过程的自动化。The flow monitoring is one of the important parts for grouting in bed - separation of overburden. By making use of the optical grating measuring technology, the concentration determination of liquid - solid two - phase flow has been realized. And by programming, Programmable Logic Controller is used to con- trol the whole process of flow monitoring. The estimated error of the grating measuring system is between - 0. 083% ~ ＋ 0. 248 %. The grating measuring system can reduce the cost of flow monitoring and achieve the automation of monitoring process for grouting with fly ash.
