AI Technical Summary

Technical Problem

In the coal preparation plant, manual control during coal blending and loading is inefficient, and the lack of online monitoring means leads to lagging test indicators, unstable coal quality, and easy occurrence of substandard or excessive coal quality, which affects economic benefits.

Method used

An online coal quality tester and a 3D radar volume monitor, combined with a belt scale, are used to monitor and adjust the coal quality and quantity in the coal bunker in real time. The optimal blending ratio is calculated by exhaustive method to ensure that the coal quality of the loaded train meets the standards.

Benefits of technology

It has enabled automated control and precise coal blending in coal preparation plants, improved coal quality stability, avoided the phenomenon of selling coal at a lower grade and excessively high coal quality, and enhanced economic benefits.
