张马屯铁矿Ⅱ号矿体开拓工程设计和施工优化

Design and construction optimization ofⅡore body development project in Zhangmatun iron mine

针对张马屯铁矿Ⅱ号矿体开拓工程设计存在问题,用溜井放矿代替轨道上山的矿岩串车提升,进一步优化设计和施工,将原设计中不利于生产使用的开拓工程进行改进,使工程更合理,更利于生产使用。优化溜井布置,增加措施工程,提前施工中间阶段水平工程;排碴工艺的改进降低了轨道上山施工难度,加快了进度。

Aiming at the problems existing in the development engineering design ofⅡore body of Zhangmatun iron mine,ore pass drawing is used to replace the lifting of ore and rock in rail climbing,further optimize the design and construction,improve the development project which is not conducive to production and use in the original design,so as to make the project more reasonable and more conducive to production and use.Optimization of chute layout,increase of measure engineering,advance construction of intermediate stage of horizontal engineering;improvement of ballast discharge technology reduces the difficulty of rail uphill construction and speeds up the progress.
