【摘要】 随着竖井直径的增大、深度的加深,井筒施工难度逐渐加大。结合云南驰宏锌锗股份有限公司会泽矿业3号竖井(井深1 526.5m,净直径6.5m)施工实践,对大直径深竖井的劳动组织、掘砌施工、防治水、岩爆治理以及通风、排水、供电系统等方面做了分析研究,阐述了大直径深竖井施工应注意的问题,对施工关键环节提出了新的方法和思路,对大直径深竖井施工具有借鉴意义。更多还原

【Abstract】 With the increases of diameter and depth of the vertical shaft,the difficulty of shaft construction would increase gradually.In combination with the construction practices on No.3 vertical shaft(the depth of 1 526.5 mand the net diameter of 6.5 m)of Huize Mining Branch,Yunnan Chihong Zn& Ge Co.,Ltd.,the analysis and research were conducted on the labor organization,excavation and lining construction,water prevention and control,rock burst control as well as the ventilation,water drainage,power supply and other systems of the large diameter deep vertical shaft.In the paper,the noted problems in the construction of the large diameter deep vertical shaft were set forth,and a new method and idea were provided to the key links of the shaft construction.It could have the reference significances to the construction of the large diameter deep vertical shaft.更多还原
