In blasting operation, some undesirable impacts, such as fly-rock, fragmentation, and back break, are induced. If the blasting design is not optimized, these mentioned impacts would reduce the blasting efficiency. To improve and optimize the blast design, blasting effect evaluation is essential. Due to the complexity of interactions among blasting parameters, empirical methods may not be appropriate for blast design optimization. A two-level mathematical model based on fuzzy mathematics, is proposed in this work. In total, 11 typical parameters were chosen and classified into three groups. The blasting effect is evaluated from three aspects, and then the comprehensive evaluation is given. A blasting effect evaluation system was developed based on the mentioned method on the platform of VC++. Some other techniques, such as image processing, were integrated into the system, which allowed for obtaining all of the parameters rapidly and conveniently. The system was applied in practical bench blast engineering. The results obtained from the system can provide effective information for the optimization of the next blast design.

露天矿工作台爆破性能综合评价方法

在爆破操作中，会引发一些不良影响，例如飞石，破碎和后折。如果未优化喷砂设计，则上述影响将降低喷砂效率。为了改善和优化爆破设计，爆破效果评估至关重要。由于爆破参数之间相互作用的复杂性，经验方法可能不适用于爆破设计优化。提出了基于模糊数学的两级数学模型。总共选择了11个典型参数并将其分为三组。从三个方面对爆破效果进行了评价，然后进行了综合评价。基于上述方法，在VC ++平台上开发了爆破效果评估系统。其他一些技术，例如图像处理，集成到系统中，可以快速方便地获取所有参数。该系统已应用于实际的台式喷砂工程中。从系统获得的结果可以为优化下一个喷砂设计提供有效的信息。
