2、为7号煤，平均厚度2m、7号煤，平均厚度3.5m,.工业储量125Mt，可采储量101Mt，服务年限64.74a。矿井涌水量不大，正常涌水量为16 m3/h，最大涌水量为30m3/h。矿井相对瓦斯涌出量为3.35 m3/t，属低瓦斯矿井。矿井煤尘无爆炸危险性，切不易自燃。矿井采用立井两水平开拓。采煤方法为综合机械化一次采全高开采。全矿采用胶带运输机运煤，辅助运输采用矿车。矿井通风方式为中央并列式。矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。专题部分题目是孤岛工作面危险性分析。通过对孤岛工作面上覆岩层运动规律和孤岛工作面应力分布及能量分布的研究，分析出孤岛工作面的危险性区

3、域。翻译部分是一篇关于采空区瓦斯和瓦斯抽放钻孔的论文，英文题目为Methane moving law with long gas extraction holes in goaf。关键词：立井两水平；采区；采全高；皮带； 矿车；中央并列式通风ABSTRACTThis design includes three parts: the general part, special subject part and translation part.The general part is a new design of NO.1.2 of Zhangxiaolou mine. This design

4、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 liftin

5、g 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 ha

6、s 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 i

7、s 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

8、 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

9、 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 lif

10、ting 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, analys

11、is 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
