摘要
以华亭煤田煤层力学试验数据为依据,运用SPSS软件对冲击能指数、弹性能指数、动态破坏时间、抗压强度以及弹性模量等指标进行了主成分分析,发现5个指标的试验数据存在着高度相关性,并研究冲击倾向性指标间存在的相关性及其内在构成特征。
According to the mechanical test data of coal seam in Huating coalfield, the SPSS software principal component analysis method was adopted to analyze such indexes as impact energy, elastic energy, dynamic failure time, compressive strength and elastic modulus. It has found that there is a high correlation among five indicators test data. The correlation and characteristics of impact tendency indexes were studied.
