Analysis and research on key coal quality characteristics and coal utilization ways of major coalfields in Xinjiang
The characteristics of key coal qualities in major coalfields in Xinjiang and their adaptation to coal utilization ways were analyzed,and some suggestions for the development and utilization of coal resources in Xinjiang were put forward.The results have shown that the coal qualities in Xinjiang are diverse,causing deviations in the determination of coal types for some Xinjiang coal;the fluctuations of composition,fusibility tempreture and viscosity tempreture of coal ash are significantly influenced by the content and occurrence of minerals in coal,which has a negative impact on coal processing and utilization.The mining areas in eastern Xinjiang mainly rely on coal transportation to other regions,while the Zhunnan coalfield and the coalfields in southern Xinjiang mainly meet the local demand.Zhundong coalfield,Yili coalfield and Zhunbei coalfield were suitable for constructing large-scale coal-fired power and coal chemical industry bases.During the coal utilization process,the control technology of commercial coal quality and coal ash chemical content should be established,and the data tracking and correction mechanism between coal for coal chemical projects and the geological coal quality should be established to ensure the stability of coal quality.
