露天矿中深孔爆破V_1型起爆法的应用探讨

Discusson of Application of V_1-model Igniting Method about Medium-length-hole Blasting in Open-pit Mine

为了进一步改善排间微差起爆的起爆效果,建议采用斜向排间微差起爆法(V1型起爆法)。实际效果证实,在同等条件下V1型起爆法可明显改善爆破效果。浅析了V1型起爆法爆破作用原理,给出了工程应用中应注意的事项。

To improve the blasting effect of medium-length-hole blasting, the inclined millisecond delay blasting method in rows（ V1-model igniting method） is suggested. Blasting results show that V1-model igniting method can improve the blasting effect obviously. The author analyses the action principle of V1 -model igniting method and gives some effective measures in engineering application.
