Zhangjiashan iron deposit is located in the Liaodong Peninsula of Shandong churchyard, ore with a total length of 450 meters, 1 ~ 3 m thick multilayer clamping stone, average true thickness of 619 metres, orebody occurrence highest elevation 295 m inferred the minimum height of the orebody occurrence 195 meters. Ore bearing rock is migmatitic granite, rock type is magnetite quartzite was grey, dark grey, fine-grained structure, banded, massive structure, the main ore mineral is magnetite and the gangue minerals quartz. Ore body has a certain size and industrial value. This design is used in shaft, cage shaft and the air shaft are located in the footwall. The ore body by the central diagonal ventilation, cage well as downcast, another set of two shaft, as the return air shaft. According to the geological conditions, ore geological conditions, the sublevel caving mining method in the design. Ore, waste rock by the scraper out of the stope, the cage is transported to the ground. This is divided into 2 interrupt, the retreating mining.在设计说明书中，阐述了本次设计的开拓方案、采矿方法、运输设备的选择以及通风系统和排水系统，对不同的方案作了技术经济比较，各项技术决策均有可行的依据，并且附有数据和资料，在老师的指导下，并运用课堂上积累的知识，查找有关资料和文献，力求设计出一个合理可行的矿山设计。 In the design specification, this paper expounds the development scheme of the design, mining method, transport equipment and ventilation system and drainage system, the different schemes for the technical
