煤炭资源优质等级评价方法研究

Study on High Quality Grade Evaluation Method of Coal Resources

煤炭资源优质等级评价为合理开发利用煤炭资源及制定煤炭工业规划提供依据。基于煤炭地质勘查获得的煤质资料,在前人研究成果的基础上,依据新的标准和规范,针对山西省炼焦煤、动力煤及化工无烟煤,确定了煤炭优质评价指标体系和评价指标划分方案,利用离差最大化和专家打分相结合的方法确定各指标权重,建立了基于灰色关联分析的煤炭资源优质等级评价模型。以此为依据,对山西省三个勘查区的煤炭资源进行了优质等级评价。

According to current standards and specifications, and based on the coal quality data obtained by the coal geological exploration and the predecessor＇s research achievements of coal quality evaluation, the index system and the index weighting scheme were established for the high quality grade evaluation of coal resources. Taking the coking coal, steam coal and chemical anthracite in Shanxi as samples, the combined method of maximum deviation and the expert marking was applied to determine the weight of each index. The dynamic mathematical models of the coal resources quality grade evaluation were established, based on the grey correlation analysis. Applying these models, the high quality grade evaluation of coal resources in three exploration areas in Shanxi was carried out.
