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 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 1 ~ 8 Mining method for the shorthole shrinkage method, the digging height is 50 meters, and in 5 phases layout the roadway .The ventilation system adopt the centraldiagonal 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. The drainage system adopt the integrated drainage. In addition, such the size of the shaft section, the size of the road section , the choose of the electric lootive, the choose of the the mine car, the choose of the drawing equipment , the choose of the ventilation equipment, the choose of drain equipment are also related to the design . Keywords: Under footwall of the vertical shafts development。 Centraldiagonal ventilation system。 交通位置 阿右旗鐵礦，位于內(nèi)蒙古阿拉善右旗卡休他他北約 公里，南距蘭新鐵路河西堡車站直距 137 公里，有簡(jiǎn)易公路，行程 171 公里。據(jù)一九六五年至一九六八年阿右旗氣象臺(tái)資料，年平均氣溫 ℃，七月最高氣溫 ℃，元月最低氣溫℃，日溫差一般 18℃ — 19℃。年蒸發(fā)量 4000—— 4500 毫米，濕度系數(shù) —— 。 礦區(qū)南部山區(qū)屬剝蝕殘山低山丘陵，山勢(shì)低緩，分水嶺開(kāi)闊山前洪積，風(fēng)積平原寬約 3— 4 公里，地形平坦，坡降約千分之五。下部為未膠結(jié)的砂礫，一般不含水。其特點(diǎn)是：地層簡(jiǎn)單，構(gòu)造以斷 裂為主。 礦區(qū)地層為一走向近東西，傾向南，傾角 42— 78 度產(chǎn)單斜構(gòu)造，僅局部見(jiàn)
