灰色聚类分析在煤炭资源有效保障能力评价中的应用

Application of grey clustering analysis in evaluation of effective supply capacity of coal resources

摘要: 在灰色系统理论与煤炭资源评价实践有机结合的基础上,讨论了煤炭资源评价单元的灰色特征,分析了灰色聚类分析应用于煤炭资源评价的原理,给出了煤炭资源评价中的灰色聚类分析的计算方法。以贵州省9个煤炭资源评价单元为例,参考18个评价指标,按照既定的优、良、可、差等级划分标准,计算出其综合优度值,得到评价结果为4良、4可、1差,并给出开发的先后顺序。结果表明,该方法具有较大的实用性。

Abstract: On the basis of the grey system theory with the evaluation of coal resources,the paper discusses the grey characteristics of evaluation unit of coal resources,analyses the basic principles of evaluation of coal resources with grey cluster,and gives the calculating method in the evaluation of coal resources.Taking 9 evaluation units of coal resources as an example,the comprehensive subjection value was calculated based on 18 evaluation indexes and rating standard(excellent,good,acceptable,poor).The assessment results are obtained as 4 good,4 acceptable,1 poor and the sequence of exploitation is given at last.The results demonstrate that this method is reliable.
