蒙库铁矿井下矿挂帮矿主溜井及硐室施工技术探讨

摘要

蒙库铁矿井下矿一期工程建设任务紧，地质围岩条件复杂。盲溜井及大硐室是矿建的重要单体工程，工程建设过程中施工工期长、工艺复杂、危险性高。文章介绍了为保证安全高效的施工，挂帮矿体主溜井及溜井下部硐室采用反井钻机打导孔、吊罐钻爆法刷大井筒等技术，取得了较好的施工效果。%Because the phase I project of underground mine in Mengku iron mine is urgent, the condition of surrounding rock is complicated, and blind chute&chamber are important single projects in mine construction which are featured of long duration, complex technology and high risk. The article introduces how to effectively and safely build the main chute of hanging wall ore and chute lower chamber by perforation with raise boring machine and brushing well bore with drilling and exploding method ,that have obtained good results.
