从预测大气模型和测声设备中获得的数据输人到大气折射模型、从而能评价气象对爆炸现场周边区域内的冲击波能级的影响Real-time data from a predictive meteorological model and sounding equipment is input to an atmospheric refraction model that enables the effect of meteorology on airblast levels in the area surrounding the blast site to be evaluated
有人证明使用这种破碎带模型、遇到各种岩石和爆破环境时、能可靠地估算过筛直径为1mm 碎岩的比例The crushed zone model has been shown to provide a realistic estimate of the proportion of fragments passing 1 mm for a wide variety of materials and blasting situations
然而、大规模减少单位炸药消耗量是不可取的、因为这样反倒影响破碎作用和排石量It is not recommended, however, to reduce the powder factor significantly because it will adversely affect the fragmentation and
科学模型、或者说基本模型、试图立足于现实、描述爆破的物理效果和岩石的力学回应Scientific or fundamental models attempt to realistically describe the physical effects of blasting and the mechanical response of the rock
评估是否准确、取决于气象资料和所用的评价模型是否精确The accuracy of the assessment depends on both the accuracy of the meteorological data, and the accuracy of the assessment model used
通常用于爆破设计和破碎模型中的这些参数、都是静态的、而非动态性质、只不过在用于模型时经验因素弥补了这种反常The parameters that are generally used in blast design and fragmentation modeling are the static rather than the dynamic properties, but empirical factors used in the models compensate for this anomaly
