大井径原井位延伸凿井设备的布设与应用

Layout and Application of Shaft Sinking Equipment for Extension of Large-diameter Original Shaft Position

结合金属矿山盲竖井项目设计经验,以某大型铁矿二期扩建工程主副井延伸为例,对原有传统施工技术进行优化,在确保符合施工标准的前提下,减少竖井施工难度,降低成本,保证施工安全可靠。

With the experience in design of interior shaft project of metal mine and taking the main and auxiliary shaft extension of the second phase expansion project of a large iron mine as an example,the original traditional construction technology was optimized to reduce the difficulty of shaft construction,reduce the cost and ensure the safety and reliability of construction under the premise of meeting the construction standards.
