斜沟煤矿选煤厂集控操作系统的应用研究

为提高选煤厂生产的自动化程度,加强对选煤过程的控制,促进选煤厂安全高效生产,保证产品指标的合格稳定。根据斜沟煤矿选煤厂原煤处理量大、介质系统多、设备台数多,不同原煤性质差异大的特点,引进了选煤厂集控操作系统。从集控系统的配置与设置、集控功能的实现和集控在生产过程中的调节3方面进行了论述。2014年上半年销售精煤合格率100%,混煤合格率100%,介耗1.41 kg/t、电耗6.51 k Wh/t。指标证明了该操作法完全适应本厂工艺、煤质特点。 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 preparation,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 k Wh 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
