The general design is about a 1.5 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; 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, Shangxi province. As shitai railway and taijiu highway run across the southern part of the mining field, the traffic is very convenient. It’s about 5 km on the strike and 5.5 km on the dip,with the 27.5 km2 total horizontal area. The minable coal seam of this mine is 15low with the average thickness of 3.6 m , the average dip of 8 ° . The geological resources/reserves of this coal mine are 154.82 Mt, the proved resources/reserves are 151.72 Mt , the designed resources/reserves are 148.00 Mt and the minable resources/reserves are 116.23 Mt, with a mine life of 55.88 years.The geological condition of the mine 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 it’s a coal that has no dust explosion. This mine adopts vertical shaft development with one mining level and 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 “four-six ” working system is applied for coal mining . The monographic study is a thermal analysis of the gas pulling out in Xinyuan. The translated academic paper is about cutting scale machine in the coalmine shaft. Its title is that Research and development on cutting scale machine in the coalmine shaft. Keywords：vertical shaft development; strip district ; longwall mining to the dip or to the rise; great mining heigh.
