The general design is about a 0.9 Mt/a new underground mine design of Zhangxiaolou coal mine.The whole article is divided into ten parts: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The designed productive capacity, service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The explorer method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms. Zhangxiaolou coal mine lies in Xuzhou, Jiangsu province. This mine has special railway and is connect to Longhai railway, the traffic is very convenient.It’s about 5.0 km on the strike and 3.4 km on the dip,with the 15.944 km2 total horizontal area.The minable coal seam of this mine is only 7 with an average thickness of 3.2 m and an average dip of 16°.The proved reserves of this coal mine are 71.53 Mt and the minable reserves are 47.23Mt, with a mine life of 40.38 a.The geological condition of the mine is relatively simple.The average thickness of topsoil is 87 m.The normal mine inflow is 208 m3/h and the maximum mine inflow is 268 m3/h. The absolutely gas discharge quantity is 10.51 m3/t .It is a lower gassy mine.It’s a coal seam liable to explosion. The productive capacity of Zhangxiaolou Mine is 0.9 million tons per year，and the service life is 40.38 years.The mine pit uses the vertical shaft single level to add the inside slope development way. Designed first mining district makes use of the method of preparation in mining area, the length of working face is 180 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 0.6 m, and quantity of 2626.38ton coal is maked every day. 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 4693.8 m3 per minute, the total mine ventilation resistance is 1641 Pa, the coefficient of resistance is 0.268 N·s2/m8, equivalent orifice is 2.3 m2. At the difficult time of mine ventilation, the total air quantity is about 4693.8 m3 per minute, the total mine ventilation resistance is 1908Pa, the coefficient of resistance is 0.3118 N·s2/m8, equivalent orifice is 2.13 m2. The monographic study is about '"The present situation and control of Zhangxiaolou coal mine high temperature and heat harm". The translated academic paper is about"Gas content based outburst control technology in Australia"。 Keywords：vertical development; up-dip and down-dip minging; fully mechanized; single thunnel drivage; centralized juxtapose ventilation. 1
