基于ISABO-SVM的冲击地压危险等级预测
Prediction of rock burst risk level based on ISABO-SVM
摘要
Abstract
This paper intends to improve the prediction accuracy of rock burst risk level by establis-hing an improved subtraction average algorithm to optimize the support vector machine prediction model.By extracting five time-domain characteristic parameters including rising time and absolute energy of a-coustic emission signals,and combined with the compressive strength of coal and rock mass,the study is performed by constructing the characteristic parameter database of rock burst prediction;calculating the comprehensive risk index of each sample according to the characteristic parameter database,and dividing the risk of rock burst into four grades;taking the characteristic parameter database and the risk level as the model input and output;and predicting the kernel parameters and penalty factors in the process of the risk level of rock burst by optimizing SVM with ISABO.The results show that compared with the tradi-tional SVM model and the SVM model optimized by the subtraction average algorithm,the prediction ac-curacy of the established ISABO-SVM model is improved to 98%.关键词
