井巷掘进过程中,爆破效果的好坏直接影响整个施工的速度、质量、费用等。传统的评价爆破效果的方法仅局限于对单一方面(如炮眼利用率、爆堆形状、超欠挖程度、大块率等)进行定性描述。作者运用模糊数学的基本原理,在对现场试验数据进行收集整理的基础上,提出了一种定量、综合评价爆破效果的方法——模糊综合评判。评价爆破效 During tunneling, the blasting effect has a direct impact on the speed, quality and cost of the whole construction. The traditional method to evaluate the blasting effect is limited to the qualitative description of a single aspect (such as the blasthole utilization, the shape of the blasting pile, the degree of over-under-excavation, the bulk rate, etc.). Based on the basic principles of fuzzy mathematics, the author put forward a method of quantitative and comprehensive evaluation of blasting effect - fuzzy comprehensive evaluation based on the collection and collation of field test data.
