QIU Guanglei
Abstract：The Xiegou coal mine preparation plant had the characteristics of large raw coal handing capacity,lots of equipments and major fluctuations of raw coal properties.In order to improve the automation degree of coal preparation plant,strengthen the control over the prepa-ration,promote the safety and efficient,ensure qualified and stable product index,the preparation plant adopted a control operating system. The paper introduced its configuration,functionality realization and adjustment in the production process.The qualification rate of clean coal and mixed coal were 100%,the medium consumption were 1.41 kg,the energy consumption were 6.51 kWh for per ton raw coal in the first half of 2014.The indicators showed that the operation method fully met the requirements of process and it also accommodated to the change of raw coal properties.
