摘要
陡倾角、大直径、长斜井开挖施工难度大、危险程度高。为保证施工顺利进行,且提高安全性,对正反导井及扩挖系统进行了多项技术改进,提高了安全系数。在实际施工中各项系统运行良好,为进一步完善系统提供了依据。
The excavation of long shaft under high dip angle and large diameter has a big difficulty and a high risk. The some techniques of guide shaft and expansion excavation are improved for assure the successful construction and raise the safety coefficient. The operation of various systems is good in the construction for provide the basis to perfecting the system.
