新城金矿盲竖井矿石溜井塌方段快速修复施工技术与实践

摘要

新城金矿盲竖井矿石溜井在生产过程中-830 m 水平至-930 m 水平井壁多次塌方，大块毛石堵塞下部振动放矿机，造成盲竖井矿石提升系统瘫痪。矿石溜井修复期间，结合现场施工条件，采取简单实用的施工设备，严格按设计要求施工，圆满地完成了该工程，并介绍了该段矿石溜井快速修复的成功经验。%For the ore chute in Xincheng Gold Mine,the ore lifting system broke down in the blind shaft as a result of several collapses of the horizontal well walls ranging from -830m to -930m in production process and subsequent blocking of large bubbles in the lower vibrating ore - drawing machine. In order to repair the failing ore chute,simple and practical construction equipment are used and construction as set out in the design by taking into account field construction conditions are carried out. At the end,the project achieves complete success at a high rate of speed. The article mainly provides successful ways of quick repairing the section of the ore chute.
