摘要
以大红山铜矿主溜井的修复为工程背景,介绍了井壁安全处理的基本思路、施工方法及加固方案和技术,尤其是主溜井井壁凸出岩块和严重垮塌部位的独到的加固工艺。可以为同类矿山溜井井壁安全处理借鉴和参考。
With Dahongshan copper mine as the engineering background,this paper introduces basic ideas of sidewall safety handling, concrete construction plan, reinforcement plan and technology, especially the ones with protru- ding rock mass and the seriously collapsed parts of the wall rock. It proves to be referential to other mines with similar conditions in sidewall safety handling work.
