中文摘要:吴集铁矿岩石属于很硬岩,在井巷掘进过程中,钻孔眼爆破均比较困难。为改善凿岩技术,提高生产效率,引进使用全液压凿岩台车作业;。同时对凿岩爆破参数进行设计优化,通过经分析计算,选用五空孔直孔眼掏槽和光面爆破技术;,最后根据岩石性质,合理布置装药参数和装药结构,并对警戒范围进行理论推算,确保施工安全。方案实施后,施工效率以及安全性等方面得以改善,同时通过成本分析明确未来成作业成本管控方向,根据岩石性质,合理布置装药参数和装药结构,并对警戒范围进行理论推算,确保施工安全。最后对施工质量控制以及台车使用效果和成本进行分析,为类似矿山提供借鉴经验。

Application of Rock Drill Jambo in Roadway Excavation of Hard Rock Mines
Abstract:The rock of Wuji Iron Mine belongs to very hard rock. Drilling and blasting are difficult in the process of roadway excavation. In order to improve rock drilling technology and production efficiency, full hydraulic rock drill jambo was introduced. At the same time, the parameters of rock drilling and blasting are designed and optimized. Through analysis and calculation, five-hole cutting and smooth blasting technology are selected. Finally,according to rock properties, explosive filling parameters and structure are reasonably arranged. Blasting warning range is calculated theoretically to ensure construction safety. After the implementation of the scheme, construction efficiency and safety have been greatly improved, and the future direction of cost control has been clarified. These provide experience for similar mines.
