摘要
介绍了某铀矿的回风井在采用普通吊罐法施工,受设备限制不能满足设计通风井规格要求的情况下,尝试先对回风井采用吊罐法贯通,再对井筒采用浅孔分段爆破技术进行扩井的方案设计和施工。实施后通风效果好,达到了预期要求,可为相关工程提供有益的参考。
The ordinary bucket method is employed for the return air shaft construction in a uranium deposit.Because of equipment constraints,ventilation cant meet the design requirements.For solving this problem,firstly,ordinary bucket method is used to cut-through return air shaft by the uranium mine;then,shallow hole segmented blasting technology is employed for extension well diameter in order to meet the requirement of the ventilation.The design scheme and construction of extension well by shallow hole blasting technology to enlarge well are introduced in detail.The technique has reached the expected requirement.The practice experience can provides the beneficial reference for related projects.
