古城煤矿副立井井筒掘砌施工技术

摘要

In order to speed up the construction of secondary shaft excavation in the Gucheng Coal Mine, optimize the on-site construction equipment and technology, we scientifically organize and rationally layout, use the rapid construction mechanization line construction in the excavation process, and continuously carry out technical innovation to overcome the difficulties in the construction process. The comprehensive water prevention technology for mine shaft is applied mainly using grouting supplemented by measures such as "cutting, guiding, blocking, and discharging". It has greatly shortened the construction cycle of the mine joint project and created good conditions for shaft equipment.%为加快古城煤矿副立井井筒掘砌施工,对现场施工装备和工艺进行优化,科学组织,合理布局,在掘砌过程中采用快速施工机械化作业线施工,不断进行技术革新攻克施工过程中的难点.在井筒防治水方面采用注浆为主、"截、导、堵、排"等措施为辅的综合防治水技术.大大的缩短了矿井一期工程的建设周期,为井筒装备创造了良好的条件.
