摘要(Abstract):

提出了延时爆破工程中起爆延期等时线的概念,阐述了等时线的生成及其计算机辅助制图原理,并以典型工程方案为例,对等时线在爆破工程中的应用效果进行了检验。结果表明,等时线分析技术在预测爆破、方案优化设计?判断爆破瞬间自由面生成形态与爆破体抛掷主导方向以及爆破效果等方面,具有便捷直观?可靠有效等优点。
The conception of isochrones of initiation delay for millisecond blasting engineering was provided.Computer aided drawing based on isochrones generating algorithm was explained.The application effect of isochrones analysis in blasting engineering was checked up with typical engineering project examples.The results showed that isochrones analysis was convenient,reliable and effective,which had advantage in predicting blasting effect,optimizing blasting scheme,and judging instantaneous morphology of free face and the main thrown direction.
