2007年,我公司计划对1330m平台实施最后一次降段爆破,但爆区东侧临空面距2号窑生产现场非常近,最近距离不到15m,因此,对爆破作业的安全性提出了非常高的要求,既要保证爆破效果,又要为后续清挖作业创造条件,同时还要保证控制好爆破后碎石的飞行距离。此次爆破,我们首次采用了间断不耦 In 2007, our company plans to implement the last descending blast on the 1330m platform. However, the blasting area east of the blast surface is very close to the production site of No. 2 kiln and the distance is less than 15m recently. Therefore, the safety of blasting operation is very high High requirements, it is necessary to ensure the blasting effect, but also to create conditions for follow-up excavation operations, but also to ensure that the blast control of the flying distance after the gravel. The blasting, we first used a discontinuous coupling
