Prediction method of rock burst proneness based on rough set and genetic algorithm

A new method based on rough set theory and genetic algorithm was proposed to predict the rock burst proneness. Nine influencing factors were first selected, and then, the decision table was set up. Attributes were reduced by genetic algorithm. Rough set was used to extract the simplified decision rules of rock burst proneness. Taking the practical engineering for example, the rock burst proneness was evaluated and predicted by decision rules. Comparing the prediction results with the actual results, it shows that the proposed method is feasible and effective.
