A Decision Tree for Rockburst Conditions Prediction

Abstract

This paper presents an alternative approach to predict rockburst using Machine Learning (ML) algorithms. The study used the Decision Tree (DT) algorithm and implemented two approaches: (1) using DT model for each rock type (DT-RT), and (2) developing a single DT model (Unique-DT) for all rock types. A dataset containing 210 records was collected. Training and testing were performed on this dataset with 5 input variables, which are: Rock Type, Depth, Brittle Index (BI), Stress Index (SI), and Elastic Energy Index (EEI). Other ML algorithms, such as Random Forest (RF), Support Vector Machine (SVM), Artificial Neural Network (ANN), K-Nearest Neighbor (KNN), and Gradient-Boosting (AdaboostM1), were implemented as a form of comparison to the DT models developed. The evaluation metrics and relative importance were utilized to examine some characteristics of the DT methods. The Unique-DT model showed a promising result of the two DT models, giving an average of (F1 = 0.65) in rockburst condition prediction. Although RF and AdaboostM1 (F1 = 0.66) performed slightly better, Unique-DT is recommended for predicting rockburst conditions because it is easier, more effective, and more accurate.

Distriformer: Research on a Distributed Training Rockburst Prediction Method

“…Hence, researchers endeavor to integrate artificial intelligence techniques into rockburst prediction endeavors [8]. Traditional machine learning algorithms such as support vector machine [9,10], decision tree [11], and random forest [12,13] have also been employed to address the nonlinear challenges inherent in rockburst prediction. Furthermore, deep learning methods have garnered attention due to their enhanced nonlinear processing capabilities.…”
