| 摘 要： | 对受载煤体破裂过程中的声发射（ＡＥ）信号进行了测定和分析．研究结果表明，受载煤岩体的变形破裂及声发射信号并不连续，而是阵发性的．声发射信号符合赫斯特（ＲＳ）统计规律．在受载煤岩体的破裂过程中，声发射信号基本呈现逐渐增强趋势，这对于预测预报煤岩灾害动力现象有重要的意义．

| Abstract: | The acoustic emission(AE) during coal or rock fracture is measured and analyzed. The results show that AE follows R S statistic rule, and it basically exhibits gradually enhance tendency during the process.This rule is very important to the prediction of coal or rock catastrophic dynamic phenomena. |

| Keywords: | acoustic emission(AE) coal fracture R/S statistical rule Hurst index |
