跨越矿井井口的多绳提升井塔,是沟通地面与地下运输的咽喉建筑,设计时必须保证井塔结构的安全和提升系统持续的正常运转。基础结构是井塔的关键部位,与井塔的安危有直接影响,并影响井塔的建设费用,它的造价约占整个井塔工程造价的20～40％。由于地基条件和井塔结构特征的不同,也就出现了技术经济效果不同的基础型式。 我国不少矿井位于厚度大于80米的第四纪沉积层地区,立井井筒多采用冻结法施工,
The multi-rope hoist tower across the wellhead of a mine is a throat building that communicates ground and underground transportation. During the design, it is imperative to ensure the safety of the tower structure and to ensure the continuous normal operation of the system. The foundation structure is the key part of the well tower, which has a direct impact on the safety of the well tower and affects the construction cost of the well tower. Its cost accounts for 20-40% of the cost of the entire well tower project. Due to the different foundation conditions and the structural characteristics of the tower, there are also different types of technical and economic foundation. Many mines in China are located in the Quaternary sediments where the thickness is more than 80 meters. Most of the vertical shafts are constructed by freezing method.
