4、 subject part and translation part.The general part is a new design of NO.1.8 of Xinyuan mine. 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
5、layout of mining area; 6.The 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.Xinyuan mine locates at the Liyuan town，southwest of Qinxin county in Shanxi pr
6、ovince，17 km away from the center of the Qinxin county. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 5.56 km in the south and north direction while a width of 3.43 km in the east and west direction on average. The total area is Approximatel
7、y 18.75 km2. The main coal seam in the mine is only one, which is the 2# coal seam. The average angle is 5.94 degree, while the thickness is about 6.18 m. The minefield geological condition is simple.The proved reserves of the minefield are 150.9118million tons. The recoverable reserves are 121。9382
8、 million tons. The designed productive capacity is 1.8 million tons per year. The service life is 52.11 years. The normal flow of the mine is 28 m3 per hour and the max flow of the mine is 38 m3 per hour. The Relative gas discharge quantity is 4.06 m3 per ton. Thus it is Low gaseous mine. The coal d
9、ust of the mine has explosion hazard. But the coal seam is not easily spontaneous combustion. The level of spontaneous combustion is .The development of the mine is single level with a main vertical shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mec
10、hanization puts in the top coal 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 mine cars. The ventilation type is centralized juxtapose. The ventilation method is extraction.The working
11、 days in a year are 330. Everyday it takes 18 hours in lifting the coal. The working system in the mine is “four-six”.The title of the special subject part is “Study of the surrounding rock Stabilization mechanisms and support technology on the gob-side entry retaining ”. The article introduced gob
