Transportation of the underground; 8.The lifting of the mine; 9.

5、The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Guojiahe mine is located at the north of Linyou county of shananxi province, 100 km away from the center of the Baoji city. And it has convenience transportations. The shape of minefield is like a rectang

6、le which has a length of 10.8 km in the east and west direction while a width of 6.0 km in the south and north direction on average. The total area is Approximately 55.6 km2. The main coal seam in the mine is only one, which is the 3# coal seam. The average angle is 6 degree, while the thickness is

7、about 4.5m. The minefield geological condition is simple.The proved reserves of the minefield are 366.8million tons. The recoverable reserves are 261.5 million tons. The designed productive capacity is 2.4 million tons per year. The service life is 77.8 years. The normal flow of the mine is 260 m3 p

8、er hour and the max flow of the mine is 1351 m3 per hour. The Relative gas discharge quantity is 1.91 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has explosion hazard and the coal seam is easily spontaneous combustion. The development of the mine is single level with a main in

9、clined shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mechanization full-seam mining technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mi

10、ne cars. The ventilation type in the early stage is centralized juxtapose. In the late stage two air shafts in the boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “fo
