定权灰色聚类分析在采煤方法评价中的应用

考虑灰色聚类指标的重要程度不同,通过引入指标的权重对灰色聚类分析进行了改进,给出了定权灰色聚类分析方法。采用该分析方法,依某煤矿为实例,选取单产量、回采工效、设备投资以及回采成本这4种聚类指标,对该煤矿综采、高普、普采及炮采这4种聚类对象的综合技术经济效果进行了好、中、差的聚类评价,获得了比较满意的评价结果。

Evaluation of coal-mining methods with weighted gray clustering analysis

Thought the different importance of the gray clustering index, the gray clustering analysis is improved by weighted. Regarded unit capacity, working efficiency, equipment investment and working cost as four kinds of gray full mechanized mining, top end conventional machine mining, conventional machine mining and longhole mining as four kinds of gray clustering objects, weighted gray clustering analysis is used to evaluate comprehensive effect of the four kinds of coal mining methods, according to good, medical and bad classification.
