摘要
主溜井是金属矿山最重要的采矿工程之一,是矿山集贮与转运矿岩的咽喉工程,主溜井稳定与否对矿山生产影响极大,一旦破坏不但影响生产,修复难度极大,而且威胁整个溜破系统的安全。以甲玛铜多金属矿一期工程为背景,分析了2号主溜井发生垮塌的原因,介绍了2号主溜井修复与支护技术方案,提出了防止主溜井垮塌的应对措施。
Main draw shafts are one of the most important parts in mining engineering, it controls the storing and transferring of ores whose stability is so important that once failed, not only production is delayed, but also restoration project is hard to carry out, making the safety of the entire system endangered. The paper takes Jiama copper and polymetallic mine first-stage project for engineering background, analyzes the cause of No. 2 main draw shaft failure, introduces the restoration and supporting plan and in the end comes up with the prevention measures against the main draw shaft failures.
