The whole article is divided into ten parts: 1.An outline of the mine f

4、ield 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;

5、 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The Kong Zhuang Mine field is located in Xuzhou city of pei xian .The boundary of the mine field runs 3.6 km from north to south and 7km from west to east. The total plane area of the mine is about 17

6、.2 km2. In the well field may mine coal is the 7# coal. Its average thickness of the seam is 8 m and it is stable and flatly inclined. Its dip angle is 16 degree on average. The industry reserves of the mine field are 314.58 million tons and the useable reserves are 203.28 million tons. The average

7、inflow rate in Kong zhuang mine is 525 m3/h. The relative gas discharge quantity is 1.732 m3/t .It is a lower gassy mine. The coal dust doesnt have explosion hazard as well as the self-combustion tendency. The productive capacity of Kong zhuang Mine is 2.4 million tons per year，and the service life

8、is 60.5 years. The work system is 3-shift with a 8-hour workday. The mine pit uses the vertical shaft single level to add the inside slope 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 effec

9、tive working face in the mine. The working surface length is 200m. The level service big lane uses the adhesive tape conveyer transportation, the xiliary haulage uses the wire laying type electric locomotive to tow the 1t fixed box-type mine car transportation gangue and the material and so on.The m

10、ine ventilation way is central parallel type.The title of special subject is “Analysis of goaf filling technology”. The title of the translation part is Numerical Simulation of Coal and Natural Gas Cocombustion in a Rotary Lime Kiln with Different Types of Coal.Key words:vertical development; arrang
