摘　　要：为了较好地预测冲击地压,实现冲击地压发展、发生过程的动态监测,针对冲击地压发展、发生过程中应力脉冲信号幅值的变化情况,研制了冲击地压信号监测记录分机,并开发了相应的预测预报软件.监测记录分机配4组传感装置,可同时记录来自4个不同方位的应力信号,利用红外通讯适配器将记录的应力信号传输给软件分析系统来预测冲击地压.工程实践表明,预测预报系统能较好地对冲击地压的发展、发生过程进行跟踪和预测,具有较高的工程应用价值.In order to predict rock burst accurately and to monitor its development and occurrence process dynamically, we worked out a recording branch device for monitoring and measuring pressure signals and developed a prediction software relating to the device. Having four groups of sensors, the branch device can record stress signals from four different directions. Through an infrared communication adapter the recorded stress signal is transmitted to the analysis system for rock burst forecasting. Practices shows that the forecast system can track and predict the development and occurrence process of rock burst. Therefore, it is of good application value in engineering.
