气体间隔器在广西大新锰矿爆破工艺中的应用

摘要

为优化露天中深孔松动爆破方法，广西大新锰矿引进了爆破气体间隔器，对爆破工艺进行分段装药，使炸药的爆破能量得到有效利用，降低爆破大块率，减少爆破根底，直接降低爆破工艺成本及间接降低采装成本，起到了良好的爆破效果。%For optimization of open-air in deep holes in loose blasting method,Daxin Mn mine has introduced a blasting gas interval device by blasting process for segment loaded drug to make explosives of blasting energy effected.It reduced blasting chunks rate and blasting foundation,and it also directly reduced blasting process cost and indirectly reduced mining loaded cost in a good blast effect.
