煤矿长斜井双模式盾构施工风险及技术对策

Construction Risk and Technical Countermeasure of Double-mode Shield in Long Coal Mine Inclined Shaft

以双模式盾构施工煤矿斜井工程为例,从双模式盾构选型与配置、斜向始发及连续下坡掘进、原位无扩大硐室拆解等关键问题对潜在的施工风险进行了深入分析,并提出了相应对策,可供后续工程施工借鉴和参考。

This article took the coal mine inclined shaft constructed by shield method as an example, conducted an in-depth analysis of the potential construction risks in terms of the selection and configuration of dual-mode shield, diagonal originating and continuous downhill excavation, in-situ non-expanding chamber dismantling and other key issues, and put forward the corresponding countermeasures, which could provide application references for future similar engineering.
