Correlation Of Coal Quality Characteristic And Application Study On Santanghu Hanshui Springs, Hami, Xinjiang Coalfield

Coal quality characters is significant piece of coal research.It is important aspect of modern coal chemical and coal chemical technology research.Coal quality characters of deep understanding and awareness is the premise and foundation of coal utilization. It is hard to know more about coal for the complexity and diversity of the composition and structure. the correlative study among the coal quality has the great significance for getting a clear understanding of the coal essential characteristics and guiding of the coal conversion and comprehensive utilization.The systematic investigation, including proximate and ultimate analysis,maceral,processing properties and washability of coals in Santanghu Hanshuiquan coalfield, was done in this paper.Based on the experimental results and theoretical analysis,the theoretical deduction and the linear regression methods were used for fitting the correlative relationships among coal characteristics indexes and the mathematical models were obtained.The well-marked correlations exit between the calorific value and the coal ash content, the calorific value and the coal ash and moisture, the calorific value and the carbon, the calorific value and the carbon and hydrogen. However,no corresponding correlation between the calorific value and the hydrogen was observed. The bad-marked correlations exit between the hydrogen content and the volatile matter. mineral matterThe well-marked correlations exit between the mineral matter and the coal ash content. The correlations exit between the maceral and the volatile matter,the maceral and the Hardgrov grindability index.But The fitting degree is poor and the accuracy of calculation is bad.
