为了对台阶爆破效果进行评估,从爆破安全、爆破质量和爆破技术经济三个方面出发,选取了爆破飞石、大块率和爆破效率等12 个影响因素作为评估指标,并利用遗传层次分析法确定了评估指标的权重, 建立了基于AG-AHP和云物元模型的台阶爆破效果评估模型. 将所建立的模型应用于某露天铁矿4个采场爆破评估中,采用Matlab软件编程计算了爆破效果的关联度和综合关联度,研究结果表明:评估效果与实际相吻合.

In order to evaluate the bench blasting effect, considering the blasting safety, quality, technology and economy, this study chooses 12 factors to act as the evaluation indexes, such as the blasting flying rocks, boulder yield, blasting efficiency, etc. The weights of evaluation index are determined by applying GA-AHP and an evaluation model of the bench blasting effect which is based on the GA-AHP and matter element model is built. Then the established model is applied to the blasting assessment of four stopes in an open pit mine. Besides, the correlation and overall connection degree of blasting effect are calculated by using Matlab software programming. The result shows that the evaluation results are comparatively consistent with the practice.
