大涌水高温条件下千米深井的施工实践

Construction of a 1000m Plus Deep Shaft in a High Temperature and Heavy Water Flow Environment

冬瓜山主井是一条深达 112 0m的竖井 ,穿过多个含水层 ,井筒涌水量大 ,随着井筒深度的增加 ,地温也随之升高。文章在介绍井筒地质概况的基础上 ,阐述了解决井筒掘砌施工、治水、通风、降温等技术问题的作法。

A 1120m deep main shaft is constructed in Dongguanshan Copper Mine. The shaft penetrated several aquifer rock formations and heavy water flow rushes into the shaft. As it goes deeper, the temperature becomes higher. This paper presents the geological conditions of areas surrounding the shaft and how such technical problems are solved as lining of the shaft, water control, ventilation, cooling, etc.
