摘要
回顾了我国立井井筒直径及深度及其相应的施工技术装备发展历程;并从井筒直径和深度需求的角度,分析了其发展趋势,阐述了与井筒大小及深度相适应的技术装备匹配关系。指出了净直径超过10m、深度超过1 200m的超大直径深立井施工技术难题,即提升及悬吊安全恶化、提升能力骤降制约建井速度、井壁厚度及安全制约施工、井筒施工环境恶化等;提出了解决超大直径深立井施工技术难题的思路是:井架受力合理化,提升钢丝绳高强化,提升机性能高强及稳控智能化,悬吊稳控智能化,吊盘及模板迈步轻质化,抓岩清底少人化,砌壁浇注自动化,井壁安全信息化,降温通风智能化。
The paper had an review on the developing course of the mine shaft diameter and depth and the relevant construction technology and equipment in China. And from a view of the mine shaft diameter and depth requirements, the paper analyzed the development tendency and stated the technology and equipment matching relationship related to the mine shaft size and depth. The paper pointed out the construction technology difficulties of the super large and deep depth mine shaft with a net diameter over 10 m and a depth over 1 200 m. Thus the safety of the hoisting and suspension would be worse,the high reduction of the hoisting capacity would restrict the mine construction speed, the thickness and safety of the mine shaft liner would restrict the construction and ronment in the mine shaft would he worse and others. The paper provided the struction technology difficulties of the super large diameter and deep depth mine of the mine shaft headframe would be rational, the hoisting steel rope would be h the construction enviidea to solve the conshaft. Thus the stress igh strength, the hoist would be high strength performances and stable control intelligent, the suspension would be stable control intelligent, the sinking stage and formwork movement would be light, the rock loading and shaft bottom cleaning would have less labor, the concrete pouring of the mine shaft liner would be automatic,the safety of the mine shaft liner would be informationalized and the air cooling and ventilation would he intelligent.
