富水炮孔爆破施工技术研究

Study on the Construction Technology of Water-rich Blasthole

在露天爆破施工中,由于地下水及雨季,往往会形成炮孔富水,富水炮孔在装药施工过程中存在较多的问题,同时,由于炮孔富水改变了炮孔原有的装药设计,对爆破效果及爆破质量容易产生较大的影响,本文根据爆破工程实践,详细论述了富水炮孔爆破施工中存在的问题,提出了使用现场混装乳化炸药解决富水炮孔爆破质量的经验。

Because of the groundwater and the rainy season, in the open blasting construction will often form water-rich blasthole. There are a lot of problems in the process of charge loading in water-rich blasthole, and due to the water-rich blasthole changes the original charge design of the blasthole, the blasting effect and blasting quality are easy to make a big difference.Based on the practice of blasting engineering, this paper discusses the problems existing in the construction of water-rich blasthole in detail, and puts forward the experience of solving the blasting quality of water-rich blasthole with mixed loading.emulsion explosive in the field.
