Stability assessment of hard rock pillars using two intelligent classification techniques: A comparative study

One of the most challenging safety problems in underground hard rock mines is pillar stability during mining operation. This paper presents an assessment of J48 and SVC application for pillar stability prediction in underground hard rock mines. Based on a database compiled from various hard rock mines and using these algorithms, two stability graphs are developed. The performance assessment of models indicates that both models can predict pillar stability with acceptable accuracy. In comparison with logistic regression model, the prediction capability of J48 and SVC models is better, but the J48 model shows superiority over two other models.
