4、rt. The designe is the preliminary design which carries onaccording to the Henan god fir group Xinzhuang coal mine actualsituation. The N-S of the minefield is 7.5 km, the W-E is about 3.0km, the area is 22.5km2. Recoverable coal seam is two -second, and its thickness is 4.2m, and the average angle

5、is 8 degree. The geological structure of this area is simple.The proved reserves of the minefield are 129.81 million tons. The recoverable reserves are 101.36 milllion tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 60 years. The normal fl

6、ow of the mine is 252 m percent hour and the max flow of the mine is 300 m percent hour, and the gas of the mine is low, it is belong to low-gas coal mine . The mine is without the danger od coal dust explosion and no spontaneous combustion tendency.The mining method of the mine mine is tile longwal

7、l mining height in a large comprehensive mechanized mining thick mine exploitation of vertical two levels, using the strip belt typestandby mode. Tlexible belt conveyor is used in the coal teansportation. The materials and refuse are transported by tramcars tons in the ancillary transportation. The

8、methos of mine ventilation in this shift is mixed ventilation. In the early period, the central ventilation, at last, the mixed ventilation is used. The working system “three-eight” is used in this mine. It produced 330d/a.This design includes ten chapters: 1.An outline of the mine field geology; 2.

9、Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 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 min
