矿岩可崩性的可拓聚类预测研究

Study on Extension Cluster Prediction for Ore Rock Cavability

将可拓工程方法与聚类分析相结合,以矿岩的可崩性等级和影响因子构造经典域物元和节域物元,应用物元理论和可拓集合中的关联函数,建立了可拓聚类预测的简单物元模型。通过与RQD法,RMR法,MRMR法以及Q系统分级法的矿岩可崩性分级评价结果相比较,可拓聚类预测方法所获得的结果与其他评价方法的结果具有一致性,说明该方法的可行性。可拓聚类预测结果具有不仅反映事物从属级别的绝对性,而且还能反映其相对性的优点。

Combining extension engineering method with cluster analysis,the cavability level of ore rock and its affecting factors are used to construct the classic and limited matter elements.Then,a simple extension cluster prediction model for cavability types of ore rock is set up by applying the correlated functions of matter element and extension sets.According to the comparison result,the evaluation result obtained by extension cluster prediction is consistent with those respectively obtained by RQD method,RMR method,MRMR method and Q-system,which shows that the extension cluster prediction method is feasible.Furthermore,it also shows that the result gained by extension cluster prediction method can not only reflect the absoluteness of matter appurtenant grade,but also the relativity of matter appurtenant grade.
