摘要
本文对影响矿井通风可靠性的影响指标进行了分析,从详细精度和节点错误两个方面验证了决策树模型适合本课题的研究,建立了基于决策树的矿井通风可靠性预测模型,准确率比较高,说明决策树模型对矿井通风可靠性预测是可行的。
In this paper, the influence index of mine ventilation reliability is analyzed, and the decision tree model is validated from the aspects of detailed precision and node error. The mine ventilation reliability prediction model based on decision tree is established. 100%, indicating that the decision tree model is feasible for mine ventilation reliability prediction.
