Abstract:

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.
