煤岩变形及破裂电磁辐射信号的R/S统计规律

R/S Statistic Rule of EME During Deformation and Fracture of Coal and Rock

对煤岩变形及破裂电磁辐射（ＥＭＥ）信号进行了赫斯特（Ｒ／Ｓ）统计分析．研究结果表明，电磁辐射信号符合赫斯特统计规律，说明在受载煤岩的变形及破裂过程中，电磁辐射信号基本呈现逐渐增强的趋势，这对于预测预报煤岩灾害动力现象具有重要意义．

The R/S statistic analysis about electromagnetic emission(EME) during deformation and fracture of coal and rock is made. The results show that EME follows R/S statistic rule, and exhibits a gradually enhanced tendency during the process. The experimental and theoretical study makes it possible to predict the catastrophic dynamic phenomena of coal and rock.
