Optimization of scheme for extension of auxiliary shaft and south return air shaft in Changyu Iron Mine

根据常峪铁矿特点和开拓布置,提出将副井延深60m,达到能够承担粉矿清理及以上各水平提升的目的,取消了粉矿清理电梯井,南回风井延深后,尽早施工采切工程,达到了缩短建设工期的目的,简化了施工组织,取得了较好的经济效益。

On the base of the features and development arrange- ment of Changyu Iron Mine , the auxiliary shaft was deepened by 60 m to clean up pulverized ore and to lift at the various levels and elevator shaft for pulverized ore clean-up was eliminated with the good economic benefits obtained and the construction organizing simplified. After the south return air shaft was deepened, the cutting engineering works was duly carried out, achieving the purposes of shortening the construction period.
