毫秒爆破在采掘工程上,具有缩短放炮时间,改善工人劳动条件,提高爆破效果,加快掘进速度,促进工程质量,有利于安全生产等优点。在我国各煤矿得到了广泛的应用。近四年来,在七个矿务局,一百多次的毫秒爆破后,瞬时瓦斯浓度测定和近四千万发毫秒雷管的实际使用,证明 Millisecond blasting mining engineering, with shortening blasting time, improve working conditions of workers, improve the blasting effect, speeding up the tunneling speed, promote the quality of the project, is conducive to the advantages of safety in production. In our coal mines have been widely used. In the past four years, after more than one hundred milliseconds of blasting at seven mining bureaus, the instantaneous gas concentration measurement and the actual use of nearly 40 million millisecond detonators proved that
