The exploitation system of mines has an important impact on infrastructure investment,operational expenses,infrastructure construction cycle and safety production.In order to ensure the normal production and operation of the mine in later stage,the paper put forward three technically feasible schemes of exploitation system taking into consideration the occurrence condition and resources of the deep orebodies in Shanggong Gold Mine,and detailedly analyzed the schemes of exploitation system.The results showed that the scheme of combined exploitation system selected,which has taken into full account the current situation of the mine development,to excavate a new blind shaft in the No.38 line and to extend the mining shaft in No.47 line has not only the lowest total investment cost but also the shortest infrastructure construction time.In addition,it meets the demand that production capacity be increased from950 t/d to 1 200 t/d.Thus,the scheme of exploitation system is the optimal choice of the deep exploitation in Shanggong Gold Mine.
