摘要
龙首矿新1^(#)粉矿回收井已运行多年,因井下环境潮湿,电梯轿厢及井底设施锈蚀严重,电梯故障较多已不能满足安全生产运行要求;井筒附近的岩体完整性差,地应力大,局部地段错位变形,井筒急需大修,经技术经济论证,决定对电梯井进行优化改造,选用单绳缠绕式罐笼井。本文从改造方案和施工技术方面,重点论述了施工工艺,最大限度地降低了生产和施工之间相互影响,采取切实可靠的安全保障措施,确保了工程顺利完工,既节约成本又省时,为今后废旧矿井改造利用积累了宝贵经验。
The new 1^(#)ore fines recovery shaft of Longshou Mine has been run for many years,the underground environment is damp,the elevator cab and shaft bottom facilities are severely rusty,the elevator cannot meet the requirement on safe production operation due to frequent failures;the rock integrity near the shaft is poor,the geostress is large,some local sections are misplaced and deformed,so an overhaul is badly needed;through tech-economical argumentation,decision is made that the elevator shaft is upgraded and the single rope winding type cage shaft is selected.In this article,emphasis is put on the discussion of construction process in terms of upgrading scheme and construction technology,the mutual impacts between production and construction are minimized.The practical and reliable safety assurance measures are taken to ensure the smooth completion of the project,which are both cost saving and time saving,and have accumulated valuable experience for future upgrading and utilizing waste and old mining shafts.
