摘要
根据不同地域矿区30多个煤层中所选出10个样本煤层,提出综合反映煤层自燃分级的自燃倾向性、煤层厚度、煤层倾角和硫含量4个指标参数,运用模糊聚类分析法进行煤层自燃分级探讨。该法所需指标参数均可在井田地质勘探时期得到,分级简便实用。
According to ten typical coals selected from more than thirty coals in different mine fields,the paper proposes four parameters,which are inclination of spontameous combustion of coal,thickness of coal,inclination of coal and sulpher content,describing the classification of coal comprehensively.It will be usefull to some extent in mine.
