南非深竖井施工关键技术研究

Research on the key technology of deep shaft sinking in South African

随着井筒深度的增加,深竖井施工遇到了诸多困难和问题,以提升吊挂技术制约井筒向纵深延伸最为显著。基于研究中国传统竖井施工工艺和配套技术,分析制约国内深竖井施工工艺中悬吊设备设施、安全保障、水害防治等关键技术难点,对标研究南非解决深竖井施工技术难点的关键技术。本文研究内容可为升级国内深竖井施工工艺及配套技术提供重要依据,对储备2000m以浅深竖井施工关键技术具有重要借鉴意义。

With the increasing of shaft depth,deep shaft sinking has encountered many difficulties and problems. The most significant difficulty is the hoisting and hanging technology which restricts shaft sinking to more depth. Based on the study of Chinese traditional shaft sinking technology and relative technology, the key technical difficulties restricting the suspension equipment and facilities, safety and water control during shaft sinking were analysed. To solve the problems,corresponding shaft sinking technologies in South Africa were researched. This can provide important basis for upgrading Chinese shaft sinking and relative technology of deep shaft. It has great significance for researching deep shaft sinking technology of shallower shaft than 2 000 m.
