对应分析是一种多元分析方法。本文在简要地阐明其基本原理的基础上,通过对陕西省黄(陵)～陇(县)煤田中段——彬(县)～长(武)矿区延安组8号煤层七个控制因素进行对应分析,确定了主要控煤因素及其与8号煤发育程度的关系。虽然将对应分析用于控煤因素研究只是一次初步的尝试,但事实证明,与常规方法相比,这种方法既可提取综合的隐藏信息,从定量分析中得出较为切合实际的结论;又可大大提高工作效率,节省时间和经费。因此,这是一种判别准确,效率较高的分析方法。 Correspondence analysis is a multivariate analysis. Based on a brief description of its basic principle, the paper compares seven control factors of Yan’an Formation No. 8 coal seam in the middle section of Huangling (Lingling) ~ Longxian (Shaanxi) ~ Bin (Xian) ~ Changwu Analysis, to determine the main coal control factors and their relationship with the development of No. 8 coal. Although it is only a preliminary attempt to analyze the factors of coal control, it is proved that compared with the conventional method, this method can extract comprehensive hidden information and draw more realistic conclusions from the quantitative analysis. Can greatly improve work efficiency, save time and money. Therefore, this is an accurate and efficient analytical method.
