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．
Hurst (R / S) statistical analysis of coal and rock deformation and broken electromagnetic radiation (EME) signals was carried out. The results show that the electromagnetic radiation signal complies with Hurst’s law of statistics, indicating that the electromagnetic radiation signal basically shows a gradual increase in the deformation and rupture of the loaded coal, which is of great significance for predicting the dynamic phenomenon of coal and rock disasters.
