Its about 10.27 km on the strike and 3.29 km on the dip,with the 32.04 km2 total horizontal area. The minable coal seam of this mine is only 7# with an average thickness of 5.0 m and an average dip of 18. The proved reserves of this coal mine are 224.678 Mt and the minable reserves are 153.331 Mt, with a mine life of 65.53 a.The geological condition of the mine is relatively simple. The normal mine inflow is 200 m3/h and the maximum mine inflow is280 m3/h. It is bituminous coal 44 with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal seam liable to explosion.Based on the geological condition of the mine, I bring forward four available project in technology. The fourth project is the best comparing with other three project in technology and economy. The first level is at -600 m, The second level is at -1000 m, Because a major fault lies in the center of mine field, the mine field is divided into the north section and the south section, the south section is one level service scope, and the north section is two level service scope.Designed first mining district makes use of the method of preparation in mining area, the length of working face is 170 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The working system is “three-eight”,with two teams mining, and the other overhauling. Every mining team makes three working cycle, with six working cycle everyday. Advance of working cycle is 0.865 m, and quantity of 5632.603 ton coal is makedeveryday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cage to be assistant transport. In the prophase of mining the mine makes use of centralized ventilation method,when in the evening of mining the mine makes use of areas ventilation method. At the easy time of mine ventilation, the total air quantity is 78.78 m3 per second, the total mine ventilation resistance is 2035.88 Pa, the coefficient of resistance is 0.328 Ns2/m8, equivalent orifice is 2.08 m2. At the difficult time of mine ventilation, the total air quantity is about 78.78 m3 per second, the total mine ventilation resistance is 2182.84 Pa, the coefficient of resistance is 0.352 Ns2/m8, equivalent orifice is 2.01 m2. The cost of the designed mine is 110 yuan per ton.The translated academic paper is about EME in the rock burst .Keywords：shaft; up-dip and down-dip minging; double thunnel drivage; centralized juxtapose ventilation
