4、n of an academic paper.The general design is about a 4.0 Mt/a new underground mine design of kaiyuan coal mine. It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system, designed mine capacity and mine life;

5、 4.development of mining field; 5.preparation in strip district; 6.coal mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.Kaiyuan coal mine lies in Yangquan, Shangdong province. As shitai railway and taijiu

6、highway run across the southern part of the mining field, the traffic is very convenient. Its about 5 km on the strike and 5.5 km on the dip,with the 27.5 km2 total horizontal area. The minable coal seams of this mine are 3 and 9 and 15 with the average thickness of 3.03 m and 4.26 m and 3.98 m , th

7、e average dip of 7.5. The geological resources/reserves of this coal mine are 478.88 Mt, the proved resources/reserves are 456.80 Mt , the designed resources/reserves are 455.65 Mt and the minable resources/reserves are 445.56 Mt, with a mine life of 72.72 years.The geological condition of the mine

8、is relatively simple. The normal mine inflow is 140 m3/h and the maximum mine inflow is 220 m3/h. It is lean coal with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal that has no dust explosion.This mine adopts vertical shaft development with one mining level and

9、centralized ventilation. The adopted coal winning method is longwall mining to the dip or to the rise. The belt conveyor is applied to transport coal and track transport, is used in the auxiliary conveying. The workers work 330 days per year ,and exaltate 16 hours one day .The “three-eight” working

10、system is applied for coal mining . The monographic study is Analysis on Roof Structures Stability of Longwall Mining in Shallow Seam.The translated academic paper is about Reinforcing Coal Mine Roof with olyurethane. Its title is that Reinforcing Coal Mine Roof with olyurethane Keywords：Coal mining
