The general part is a new design of NO.1.2 of Zhangxiaolou mine. This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield; 5.The layout of mining area; 6.The 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. No.1.2 of Zhangxiaolou locates at the west of Xuzhou , 13 km away from the center of the town. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 4.8km in the east and west direction while a width of 3.53 km in the south and north direction on average. The total area is Approximately 16.94km2. The main coal seam in the mine are two, which are the 7# coal seam and the thickness is about 2.0 m ,and the 9# coal seam the thickness is about 3.5m . The average angle is 20 degree. The proved reserves of the minefield are 125million tons. The recoverable reserves are 101 million tons. The designed productive capacity is 1.2million tons per year. The service life is 64.74 years. The normal flow of the mine is 16 m3 per hour and the max flow of the mine is 30 m3 per hour. The Relative gas discharge quantity is 3.35 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is low. The development of the mine are two levels with a main inclined shaft. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type is centralized juxtapose. The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”. The title of the special subject part is “Island coal mining face risk analysis”. Through the study of island coal mining face of overlying strata movement ,and island coal mining face stress distribution and engergy distribution, analysis of risk area of island coal mining face. The translated academic paper is aboutt the mathane moving in goaf and the long gas extraction holes. Its title is “Methane moving law with long gas extraction holes in goaf”. Keywords: Two levels of the shaft; district; mining high belt; trams; Central side-by-side ventilation.
