It 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 layout of panels; 6. The method used in coal mining; 7. Underground transportation of the mine; 8. The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10. The basic economic and technical norms of the designed mine.Kongzhuang mine of Datun is located in northwest of Xuzhou mining area. The taffic of road and railway is very convenience to the mine. The length of the coalfield is 4.84 km, and the width is about 3.69 km, and the toal area is 17.25 km2. The seventh is the main coal seam, and its general trend is north low, and its dip angle 15 degree. The thickness of the mine is about 8.6 m in all. Within the coalfield, the geological structure of the seventh coal seam is stable. The recoverable reserves of the minefield are 207.10 million tons, and the minable reserves are 132.90 million tons. The designed productive capacity is 1.8 million tons percent year, and the service life of the mine is 52.74 years. The normal flow of the mine is 190 m3 percent hour and the max flow of the mine is 340 m3 percent hour. The relative mine gas gush is 0.77 m3 percent ton , so it is a low gas mine.According to the geological conditions, I put forward four technically feasible development plans. Through the technical and economic comparison, the best plan choosed finally is two mining levels with vertical shafts and expanding to second level by shaft directly. The design applies disttict preparation against the first band. The length of working face is 192 m, using top coal caving to exploit coal, falling to dispose worked out sections. In Kongzhuang mine, it products for 330 days percent year and uses “three-eight”working system. Two and a half class product and a half examines and repairs. The depth-web is 0.6 m with five working cycles per day, and daily production is 6261.20 tons.Te central laneway uses Belt Conveyer to transit coal, and 1.5 t trolley wagons are used for accessorial transportation in the roadway. The mine uses diagonal ventilation system at earlier stage and uses juxtaposition ventilation system at later stage.The topic of special subject part is the analysis of roadway supporting technology in deep roadway. It is mainly about deep roadway deformation mechanism and control measures in domestic and foreign, and expounds the mining pressure rules in deep roadway and all sorts of supporting technology.Translation part is about anchorage performance affected by rockbolt parameters. The English title is“The variability of some rockbolt parameters and their potential impact on anchorage performance”.Keywords: Shaft; Two levels; Top coal caving; Hybrid ventilation目 录一般部分1
