Research on the structure of shaft lining with asphalt block and steel-reinforced concrete at deep shaft ingate and its application
摘要
Abstract
As the ingate and lower section of the auxiliary shaft in western district of Huainan Xinji No.1 coal mine are in strongly expansive mudstone strata, it is of significance to optimize the design of shaft lining structure at this ingate through adopting a new shaft-lining structure with asphalt block and steel-reinforced concrete. The new shaft lining is composed of asphalt block buffer layer, intensive U-steel shaft frame and the reinforced concrete. Finite-element numerical simulation was conducted to investigate the mechanical-property differences between the steel-reinforced concrete shaft lining and the traditional reinforced concrete shaft lining. Results show that: compared with the reinforced concrete shaft lining, the ultimate bearing capacity of steel-reinforced concrete shaft lining increases by 22％. Meanwhile, Field monitoring on the internal forces of steel-reinforced concrete shaft lining shows that:the asphalt block layer has excellent effect of buffering and pressure adjustment. And the new shaft lin-ing has reasonable mechanical behavior and higher safety reserve. Therefore, the rationality and relia-bility of this shaft lining optimization design are verified.关键词
