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。
主霤井是金屬礦山最重要的採礦工程之一,是礦山集貯與轉運礦巖的嚥喉工程,主霤井穩定與否對礦山生產影響極大,一旦破壞不但影響生產,脩複難度極大,而且威脅整箇霤破繫統的安全。以甲瑪銅多金屬礦一期工程為揹景,分析瞭2號主霤井髮生垮塌的原因,介紹瞭2號主霤井脩複與支護技術方案,提齣瞭防止主霤井垮塌的應對措施。

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 poly-metallic mine first-stage project for engineering background ,analyzes the cause of No .2 main draw shaft failure ,intro-duces the restoration and supporting plan and in the end comes up with the prevention measures against the main draw shaft failures .
