摘要: 为预防采场安全事故,选取地下采场地质构造、埋深、围岩强度等10个因素作为采场稳定性预测指标,从收集到的实际采场稳定性数据中选取25组作为训练样本,建立采场稳定性预测的随机森林(RF)模型,通过8组测试数据预测采场稳定性;将该模型预测结果与支持向量机(SVM)模型及人工神经网络(ANN)模型的预测结果进行对比。研究表明:采用RF模型采场稳定性等级预测准确率最高,而使用SVM模型次之,ANN模型的准确率较差;用RF模型能够相对有效地判定采场稳定性。

Abstract: In order to prevent stope safety accidents, 10 factors including underground stope's geological structure, burial depth, surrounding rock strength and rock mass quality indexes are selected as the prediction indexes of stope stability, twenty-five groups are selected as training samples from the collected data on actual stope stability to build a random forest model of stope stability prediction and eight sets of test data are used to predict stope stability. A prediction result comparison is made between the model, SVM model and ANN model. The results show that the random forest model has the highest accuracy of the stope stability ratings in the examples, and the second is the SVM model, the ANN model is less accurate, and that by using the random forest model, the stope stability can be determined more effectively.

Key words: random forest(RF) model, stope stability, support vector machine(SVM), predictive accuracy, artificial neural network(ANN)
