摘　　要：为了尽量减少主观偏差对爆破效果评价模型权重分配的影响,使用AHP-Fuzzy复合方法,立足爆破质量、经济技术效益和安全风险及环境影响这3个主要方面,量化并计算爆破筑堆形状、块度分布、炸药单耗、炮孔利用率、对周边巷道围岩及对地表建筑物的影响这6个具体评价指标,提出了硬岩铀矿深孔压渣爆破综合评价模型。通过对南方某铀矿井下采场深孔爆破落矿效果的应用评价实例的验证计算,取得了符合现场实际情况的较好评价效果,对于未来进一步的研究具有积极意义。In order to minimize the influence of subjective bias on blasting effect evaluation model weights allocation,AHP-Fuzzy complex methods were used,3main aspects of the blasting quality,economic and technical benefits and safety risks and environmental impact were considered.6specific evaluation indexes were quantified and calculated,which include blasted ore pile shape,blasting fragmentation distribution,explosive unit consumption,blast hole utilizing ratio,the impact on surrounding tunnel,and the impact on surface buildings.By the study,a hard-rock uranium mine deep hole blasting comprehensive evaluation model based on AHP-Fuzzy method of was proposed.The model was applied in an evaluation of deep-hole blasting in a uranium mine in southern China.And calculation proved that the blasting effect is good,which is in line with the actual situation at the scene.This study has a positive meaning for the further research.
