The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Tian Chen mine locates at the south of TengZhou, 18 km away from the center of the town. And it has convenience transportation

6、s. Minefield has a length of 6.8 km in the south and north direction while a width of 3.3 km in the east and west direction on average. The total area is approximately 22.08 km2. The main coal seam in the mine is only one, which is the 3# coal seam. The average angle is 8 degree, while the thickness

7、 is about 5.0 m. The minefield geological condition is simple.The proved reserves of the minefield are 151.9 million tons. The recoverable reserves are 103.71 million tons. The designed productive capacity is 1.2 million tons per year. The service life is 66.4 years. The normal flow of the mine is 3

8、73 m3 per hour and the max flow of the mine is 620 m3 per hour. The Relative gas discharge quantity is 2 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has explosion hazard. And the coal seam has spontaneous combustion. The development of the mine is single level of vertical shaf

9、t. The number of the working faces is only one. Fully mechanized mining overall high extraction is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The previous ventilation type is centraliz
