摘要
针对爆破方案选择的复杂性,在灰色关联分析的基础上,利用层次分析法,结合判断矩阵对各指标进行权值分配,将指标的关联系数与其权值相结合,提出了爆破方案综合评价模型,该模型以权重的形式体现各个评价指标对整体的影响程度,利用判断矩阵进行权值分配克服了以往权重赋值主观性较强的局限,最终以关联度为定量指标来对爆破方案进行比较分析,并以回坡底矿爆破方案评价为实例,具体说明了该模型的科学合理性。
In view of the complexity in the choice of blasting scheme,based on gray correlative analysis,by means of analytical hierarchy process,judgement matrix is adopted to determine weight of each evaluating index;a comprehensive evaluation model which combines correlation coefficient with the weight of evaluating index is presented.The model embodies the influence extent of each evaluating index to the whole by weight form;it uses judgement matrix method to determine weight in order to avoid subjective factor and analyze blasting scheme by correlation degree.Evaluation of blasting scheme of Huipodi mine indicates that the comprehensive evaluation model makes results more scientific and rational.
