Thinking.In recent years, Some Domestic scholar had carried out the bastard coal interface identification method research based on tail boom vibration signal, achieved very
Effective achievement, by signal processing and feature extraction, can accurately identify bastard coal interface in the lab, but from
Practical engineering application also has very big gap, and recognition methods is also and not perfect.Simultaneously as the missing of correlation theory, serious to make
The practical application of the theoretical developments and coal rock detection technology of top coal caving coal rock detection is about carried out based on data analysis.To be clear
The essential reason and true propagation rule that signal generates under various field conditions are understood clearly, it is in the course of the research, it is necessary to right
Rock carries out quantitative analysis with vibration performance during coal impact tail boom, but lacks rational experimental provision at this stage, to test
Card and support study dies.
