5、e coal seam. The main aquifer coal seam is 72 coal seam with an average thickness of 3 m, and the dip of 72coal seam is 817. The proved reserves of this coal mine are 349.66 Mt and the minable reserves are 265.91 Mt, with a mine life of 79.14 a. The normal mine inflow is 600 m3/h and the maximum min

6、e inflow is 650 m3/h. The mine relative gas emission quantity is 22 m3/t, and the absolute gas emission quantity is 12m3/min. Thus, it is a high gas mine. The coal seam has no spontaneous combustion tendency, but the coal dust has explosion hazard.The mine is a single level in three shafts to develo

7、p. The central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway. The two main shaft to 12 t hoppers type skip carry coal, auxiliary shaft USES a pair of 1.5 t harvesters double four car transport materials and lift the cage widen p

8、ersonnel. The ventilation mode of this mine is center juxtapose form.The “three-eight” working system is used in the mine. It produces for 330 days a year. Two and a half class production, half class maintenance. ShengChanBan each class complete three coal circulation, maintenance class complete two

9、 mining cycle. Circulation footage for 0.8 m, daily output for 6958 t.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 panels; 6.

10、 The method used in coal mining; 7. Underground transportation of the mine; 8. The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10. The basic economic and technical norms of the designed mine.The topic of special subject parts is Coal gas extraction technology resear
