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 of mine; 5.The layout of mining area; 6.The method used in coal mining; 7. Transportation of th

5、e underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Zhang Shuanglou mine locates at the northwest of XuZhou, 79 km away from the center of the town. And it has convenience transportations. Minefield has a length

6、 of 5.2 km in the east and west direction while a width of 2.9 km in the south and north direction on average. The total area is Approximately 20.28 km2. The main coal seam in the mine is only one, which is the 7# coal seam. The average angle is 9 degree, while the thickness is about 5.0 m. The mine

7、field geological condition is simple.The proved reserves of the minefield are 147.68 million tons. The recoverable reserves are 108.54 million tons. The designed productive capacity is 1.2 million tons per year. The service life is 64.6 years. The normal flow of the mine is 320 m3 per hour and the m

8、ax flow of the mine is 340 m3 per hour. The Relative gas discharge quantity is 0.77 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has explosion hazard. But the coal seam has no spontaneous combustion. The development of the mine is two level of vertical shaft,deepening with Incl

9、ined Shaft. The number of the working faces is only one. Fully mechanized mining overall high extraction 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 centraliz

The working system in the mine is “three-eight”.The title of the special subject part is “Support technology in special lot of roadway”. In view of roadway special lots support issues, analysising mechan

11、ism of rock deformation, stress distribution and roadway support principle, determining reasonable support patterns, thus ensuring the stability of surrounding rock, production safety of coal mine.The translated academic paper is about the relationship between support intensity and rock deformation

12、of roadway tunnels in soft rock. Its title is “The optimal support intensity for coal mine roadway tunnels in soft rocks”.Keywords: two level of vertical shaft; deepening with Inclined Shaft;strip district; Comprehensive Mechanized mining overall high extraction; centralized juxtapose ventilation目 录
