Study on the application of a rule-based fuzzy evaluation in predicting the rock burst

For the problem of rock burst, which seriously influences the security of mines at present, the text concludes the predicting researches and summarizes the representative characteristic parameters of acoustic emission and the characteristic parameters of attribute rock. On such a base these parameters are adopted to establish the predicted model for rock burst which is based on the fuzzy logic ore. With the gathered data from Sanhejian coal mine and the information about rock burst which is applied to the model, the result has proved to be satisfied. Thus, it helps to build the foundation that the fuzzy logic is practically applied to forecasting rock burst.
