4、on is simple by Comparison.The proved reserves of the minefield are 199.9 million tons. The recoverable reserves are 136.34 million tons. And the service life of the mine is 63.88 years. The normal flow of the mine is 220m3 percent hour and the max flow of the mine is 360 m3 percent hour. The minera
5、l well gas gushes less than 0.5cm3/g, for low gas mineral well. All the coal seam does not have the danger of explorer, or burn by itself.The mine farmland is a single level in an inclined well to expand. The mine farmland signs the single level of well to expand for the double. The mine lane adopts

The well ventilated way of the mineral well is well ventilated for admixture type, expecting the central breeze well to return to breeze before, expecting to take the area breeze well to return to breeze later. The working s
7、ystem “three-eight” is used in the Chengjiao mine. It produced 330d/a.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. The
8、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 mine; 10.The basic economic and technical norms.The special subject parts of topics is Fully mechanized coal mining face top of coal caving and control.Tran
