采用实验室测试与理论分析相结合的方法,利用RMT-150B型岩石力学实验系统以及CDAE-1全数字化声发射监测及分析系统,对煤样加载过程中的应力-应变、声发射参数进行测试,并对加载过程中声发射特征进行了分析。根据加载过程中声发射参数的变化规律,借助于SAS软件,采用时间序列预测方法,建立了声发射参数预测模型,并将预测结果与实测结果进行了对比。
Using the combination of laboratory test and theoretical analysis, the stress-strain and acoustic emission parameters during the loading process of coal samples were tested by using RMT-150B rock mechanics experimental system and CDAE-1 digital acoustic emission monitoring and analysis system The acoustic emission characteristics during loading were analyzed. According to the variation rule of acoustic emission parameters during loading, the acoustic emission parameter prediction model was established by using SAS software and time series prediction method, and the prediction results were compared with the measured results.
