4、e traffic of road and railway is very convenience to the mine. The geological structure of this area is simple. The Length of the minefield is 6.87 km ,the width is about 3.62km，the area is 20.792.The 11 and 12 is the main coal seam, and its dip angle is 12 degree. The thickness of the mine is about

5、 10.39m in all. The proved reserves of the minefield are 313million tons. The recoverable reserves are 216 million tons. The designed productive capacity is 24 million tons percent year, and the service life of the mine is 69.5 years. The normal flow of the mine is 249m3 percent hour and the max flo

6、w of the mine is 563m3 percent hour, and the gas of the mine is low gaseous mine.The field has been divided three mining levels. The first level should be located at the lever of -350m, which use raise and dip mining method of vertical shaft development .The second level should be located at the lev

7、el of -550 meters , The three level should be located at the level of -800 meters According to the condition. The main shaft skip install skip and the auxiliary shaft install cage. Roadway using 3t end dump cars to transport coal, the use of auxiliary transport Renovation of 1.5t Van tub transport.

8、The two wings opposite angles ventilation system is used in the mine. The working system “three-eight” is used in the Kailuan mine. It produced 330d/a.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

9、 of mine; 4.development engineering of coalfield; 5.The layout of panels; 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.Topic is the subject of clo

10、se-thick seam mining method selection and the feasibility of mining upstream. Targeted at a coal mine occurrence of upstream mining feasibility analysis and research. Determine the ultimate way of exploitation.Translation part of main contentses is about parameter of top caving coal mining, English
