4、 per year.It has ten chapters as follows:the outline of mine and mine field geology, boundary and reserves, working system and productive capacity and service life, development method of the mine, the main roadways, coal mining method and layout or roadways in working area,transportation of undergro

5、und, mine lifting, mine ventilation and safety, main techniqueeconomic induces.The Xu Chang mine filed lies in the north of Qin Xin about 17 kilometers.The transportation is convenient and.It covers 18.93 square kilometers. The boundary of the minefield run 3.4 kilometers on the strike and the pitch

6、 length is 3.6 kilometers. The two is the main coal seam,its dip angle is 7 degree and thickness is about 4.8m on average.The proved reserves of the minefield are 109.94 million tousands the recoverable reserves are 88.84 million tons. The designed productive capacity is 1.2 million tons percent yea

7、r, and the service life of the mine is 52.9 years. The normal flow of the mine is 180m3 percent day and the max flow of the mine is 260m3 percent day. The mineral well gas gushes is lower, It is a low gas mineral well. The working system is “three-eight”.One productive place meets the requirement. T

8、he mode of development about the mine is inclined development. The mine has one levels, the level locates in the level of 840 meters.The main shaft uses adhesive tape hoisting and the auxiliary shaft adopts mine car hoisting. The working face adopts long wall retreating to the strike.Its length is 1

9、90 meters.The technology of the working face is the full-mechanized mining.Belt Conveyor to transit coal is used chiefly to transport coal, the auxiliary transportation uses 1.5t solid car. Retrograde ventilation is used for Xin Yuan coal mine.The title of the special subject part is “Research on ro

10、adway supporting technology in the fault structure zone”.The paper overviews the technology research of the roadway supporting technology in the structure zone and analyzes varied methods of the support，the supporting technology of anchor grouting. Then the best method and the final parameter are pu

11、t forward .At last the effect of the spot surve-ring is analyzed.The english topic of transportation part is Study on critical, modern technology for mining in gassy deep mines.Keywords: inclined shaft; mining area;comprehensive mechanization; endless rope winch; centralized juxtapose ventilation. 目
