Application of Fuzzy Grey Incidence Pattern Recognition Method in Rockburst Prediction

将模式识别方法用于岩爆预测研究,选取岩石弹性能量指数、脆性系数和围岩最大切向应力与岩石单轴抗压强度的比值作为岩爆灾害预测的主要影响因子,运用灰色系统理论和模糊数学原理提出了基于模糊灰关联模式识别的岩爆预测方法。利用所提出的方法对冬瓜山铜矿床岩爆倾向与烈度进行了预测研究,研究结果表明,该方法具有较高的预测精度,具有良好的应用前景。

Pattern recognition method is used to predict rockburst. The rock elastic energy index, rock brittleness coefficient and the ratio of the maximum tangential stress of surrounding rock to the rock uniaxial compressive strength are chosen as the main influencing factors for predicting rockburst. By using grey system and fuzzy mathematics theory, a new rockburst prediction method based on fuzzy grey incidence pattern recognition method is proposed and applied in the prediction research of the rockburst trend and intensity of Dongguashan Copper Mine. The prediction results indicate that the method proposed has a high predication accuracy and a good application prospect.
