2、角平均8.0，为近水平缓倾斜煤层。井田内工业储量为 947.92 （M t），可采储量为775.3 (Mt)。矿井平均涌水量为124 m3/h，相对瓦斯涌出量为0.019m3/t，属低瓦斯矿井；煤尘具有爆炸性危险，有自燃发火倾向。国投一矿设计生产能力为8.0Mt/a，服务年限为74.55年，工作制度为“三八”制。矿井采用斜井两水平直接延伸开拓方式，采用倾斜长壁综合机械化放顶煤采煤法。矿井采用一矿一面的高效作业方式，工作面长度为250m。水平运输大巷采用胶带输送机运输，辅助运输采用架线式电机车牵引1.5t固定箱式矿车运输矸石和材料等。矿井通风方式为中央并列式。专题部分：专题题目为“提高综放工作面

3、采出率的理论与技术研究”。翻译部分：是将关于一篇煤炭特殊开采的英文翻译成中文。英文题目是“Coal Mining Under Special Conditions”。 关键词：斜井开拓；二水平斜井直接延伸；带区布置；放顶煤ABSTRACTThis design contains three parts: the general，the special subject and the translation.The general part is a new design of Ha Mi a Mine 1.2 million t / a in China Investment Company.

4、 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

5、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.The Ha Mi a Mine field is located in HaMi city 190 direction 40 km place, its administrative districts of HaMi city jurisdiction

6、 of the south lake township, village in the north to the south lake located in laohutai mine field about 19 km place.The boundary of the mine field runs 6.75 km from north to south and 7.7 km from west to east. The total plane area of the mine is about 51.98 km2. In the well field may mine coal is t

7、he3#, 7# coal. Its average thickness of the seam is 2.85 m , 10.41 m and it is stable and flatly inclined. Its dip angle is 8.0 degree on average. The industry reserves of the mine field are 947.92 million tons and the useable reserves are 775.3 million tons. The average inflow rate in Ha Mi a mine

8、is 124 m3/h. The relative gas discharge quantity is 0.019 m3/t .It is a lower gassy mine. The coal dust have explosion hazard as well as the self-combustion tendency. The productive capacity of Ha Mi a Mine is 8.0 million tons per year，and the service life is 74.55 years. The work system is 3-shift

9、with a 8-hour workday. The mine pit uses the vertical shaft two level to add the inclined shaft development way. The mine pit uses moves toward the long well synthesis mechanization to put goes against the coal mining coal law.There is only one highly effective working face in the mine. The working

10、surface length is 250m. The level service big lane uses the adhesive tape conveyer transportation, the xiliary haulage uses the wire laying type electric locomotive to tow the 1.5t fixed box-type mine car transportation gangue and the material and so on.The mine ventilation way is centralized ventil

11、ation.The title of special subject is “Increase the rate of recovery of fully mechanized sub level caving face theory and technology research”. The translation part is to translate a article on the coal special mining into the Chinese. And its title is Coal Mining Under Special Conditions .Key words
