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.
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.
