多井提升平行作业在井巷工程施工中的应用

为了进一步扩大矿山生产能力，自2008 年起，三山岛金矿开始实施8 000 t/d 改扩建项目，采用多井提升平行作业方式，即将原副井和改绞后的新主混合井同时应用于新立矿区主混合井溜破和粉尘回收系统施工中，重新分配原有矿山副井提升时间，优化矿车结构，不断提高主混合井的提升重车率。同时，通过加强改绞后矿井的提升管理及改造固定式矿车等措施，提高矿井提升能力，加快工程进度，矿山经济效益显著提高。该技术对加快矿山基建开拓进度具有较好的指导意义，值得类似矿山借鉴。

The Application of Multi-well Enhance Parallel Operation in Roadway Construction

In order to further expand the production capacity of the mine,since 2008,Sanshandao gold mine began to implement the expansion project of 8 000 t/d,and used the way of multi-well enhance parallel operation,that was the original auxiliary shaft and the new primary mixed well after change twist were used at the same time in the construction of slide broken and dust recovery system of the main mixed well in Xinli mining area.We redistribute the upgrade time of the auxiliary shaft in original mine,and optimize the tub structure,continuously improve the heavy vehicles rate of the main mixed well.At the same time,by enhancing management of the mine after change twist and the transforming the fixed tub and other measures,we improve the capability of the mine,speed up the progress of the project and improve the economic benefits of the mine significantly.The technology can be a good guide for accelerating progress in developing infrastructure,it is worth learning for similar mine.
