The output of designed is annual 100,000 tons,and its life is service for 27 years. The design include some contents as follow：Comparing the choice to the program of development，designing the HYPERLINK dict://key.0895DFE8DB67F9409DB285590D870EDD/methods%20of%20extraction \o 查找: methods of extraction methods of extraction,designing ventilation systems and designing the hoisting and the transportion system and so on .In this mine,the development is the under footwall of the vertical shafts, and design the mine between the exploration line of 47 ~ 55. Mining method for the short-hole shrinkage method, the digging height is 50 meters, and in 5 phases layout the roadway .The ventilation system adopt the HYPERLINK /dict_result.aspx?searchword=%e4%b8%ad%e5%a4%ae%e5%af%b9%e8%a7%92%e5%bc%8ftjType=sentencestyle=t=central-diagonal+arrangement central-diagonal ventilation system, the main shaft use the single cage to hoist, and the two ventilation shafts layout in the two wings of the collapse area of the ore body as a safety exit.
