巴鲁巴铜矿基于加权聚类分析的岩体可爆性分级

采用加权聚类分析方法对巴鲁巴铜矿矿岩进行可爆性分级。基于岩体的密度、抗拉强度、抗压强度、岩体完整性系数这四个指标对岩体进行可爆性分级。经计算得巴鲁巴矿岩的可爆性分级为:泥质板岩、泥质石英岩为难爆岩体;白云质片岩、砾岩可爆性为中等可爆岩体;过渡带片岩为易爆岩体。岩体的可爆性分级结果,对于优化爆破参数、改善爆破效果有重要意义。

Rock-mass Blastability Classification of Baluba Copper Mine Based on Weighted Clustering Analysis

In this research, weighted clustering analysis was used for rock - mass blastability classification of Baluba Copper Mine. In order to classify the blastability, the property of rock - mass including volume - weight, tensile strength, compressive strength, fissure coefficient were took into consideration. The results show that the argillite and argillaceous quartzite are hard - to - blast, the dolomitic argillite and conglomerate are medium - to - blast, the transitional schist is easy - to - blast. The results of classifi- cation are significantfor the optimization of blasting parameters and the improvement of blasting.
