新城金矿新主井井筒净直径为φ6.7m,井口标高+32.9m(地表+32.7m),井底标高-1488.1m,井筒深度为1521m。该项目采用立井机械化配套设备施工,掘进爆破应用了中深孔光面爆破技术。同时在采取设备和施工过程中,利用了最先进的技术,与此同时为了施工现场的安全做足了充分的准备、在质量问题上也狠抓管理,达到了快速施工的工作效率,本文根据此例,介绍一下在施工现场管理中井筒的做法和施工效果。
The new main shaft of Xincheng Gold Mine has a net diameter of φ6.7m and a wellhead elevation of +32.9m (surface + 32.7m) with a bottom elevation of -1488.1m and a well depth of 1521m. The project uses shaft mechanization equipment construction, blasting application of medium-deep hole smooth blasting technology. At the same time in the equipment and construction process, the use of the most advanced technology, at the same time in order to make full preparation for the safety of the construction site, the quality of the problem also pay close attention to management, to achieve rapid construction efficiency, this article based on In this case, we will introduce the practices and construction effects of the wellbore management at the construction site.
