Aiming at problem of low efficacy of early warning of rock burst in coal mine, a multisystem and multiparameter integrated early warning method based on genetic algorithm (GA) is proposed.
In this method, firstly, the temporal-spatial-intensity information of energy incubation process of rock burst is deeply mined, and the multidimensional precursory characteristic parameter system of rock burst is constructed.
Secondly, the genetic algorithm is used to train the historical monitoring data to obtain the optimal critical value and fitness value of each precursory characteristic parameter, and then the early warning index WC of each monitoring system is calculated.
Finally, the integrated rock burst early warning index IC is obtained by synthesizing the early warning index WC of each system.
The value of IC corresponds to the specific rock burst risk level of the mine.
This method is applied to Wudong coal mine in Xinjiang, China.
Based on the actual situation of the mine, a multidimensional precursory characteristic parameter system of rock burst is constructed, which includes energy deviation (DE), frequency ratio (Fr), frequency deviation (DF), degree of dispersion (DS), and total high value of energy deviation (DH).
After analyzing the rock burst danger status and risk level in the monitoring area, the early warning capability of this method is found to reach 0.896.
Combining with the specific prevention and control measures corresponding to different rock burst risk levels, it can provide effective guidance for the field work.
