摘　　要：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。The methods of laboratory testing and theoretical analysis were used. With RMT-150B rock mechanics test system and CDAE-1 all-digital acoustic emission detection and analysis systems, the samples were tested for stress-strain-acoustic emission under the loading paths. At the same time, the characteristic of acoustic, emission in the loading process was analyzed. According to the variation of acoustic emission parameters of the loading process, the prediction model of acoustic emission parameters were established with the aid of SAS software.
