地下矿山工程井巷掘进爆破技术及实施要点分析

Blasting technology and key points for implementation of underground mine tunneling

在我国社会经济快速发展的影响下,与铁矿工程相关的施工技术得到了快速发展,有效提升了地下矿山工程的掘进速度。但是由于不同爆破技术在安全上的要求也各有不同,所以对爆破效果进行改善,实现成本的降低也就成了至关重要的环节。结合笔者多年从事地下矿山工程的工作经验,对井巷掘进爆破的技术特点、井巷掘进爆破的相关参数等方面的内容进行深入分析。

Under the influence of the rapid development of China＇s social economy, the construction technology related to iron ore project has been developed rapidly, which has effectively improved the driving speed of underground mine works. However, due to different requirements on safety of different blasting techniques, the effect of blasting is improved and the reduction of cost is a crucial link. Based on the author＇s working experience in underground mine engineering for many years, this paper makes an in-depth analysis of the technical characteristics of the excavation blasting and the related parameters of excavation blasting.
