摘要
Abstract
Engineering blasting experiments were carried out by using the electronic detonator and detonator with shock -conducting tube in Zijinshan gold copper mine. The contrast analysis of large boulder rate, shovel efficiency and the number of bottom proved that in the surface mining the application of electronic detonator could reduce the rate of large boulder, increase the shovel efficiency and improve the blasting effect. Via monitoring the electronic detonator blasting vibration , the effect of delay time was analyzed. The delay time was found out not only to affect peak speed of the blasting vibration , but also determine the size of the blasting vibration frequency and frequency distribution. And the optimal blasting parameters of delay time between holes 20 ms and between rows 73 ms were also given in the experimental condition.关键词
