The general part is a new design for Dongping mine. Dongping mine is located in Yangquan in Shanx

4、i province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 5.1km,the width is about 3.3km，and the total area is 14.3km2.The fifteenth is the main coal seam, and its dip angle is 214 degree. The thickness of the mine is about 6.45m. The g

5、eologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 126.12 million tons,and the minable reserves are 89.72 million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 54.3 years. The normal flow of the m

6、ine is 90m3 per day and the max flow of the mine is 400 m3 per day. The relative mine gas gush is 1.30 m3/t and the absolute gush is 1.85 m3/min, so it is a low gas mine. The mine is a single level in two inclined shafts to develop. Te central laneway uses Belt Conveyor to transit coal, and trolley

7、wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center unattached form.The “three-eight” working system is used in the Dongping mine. It produces for 330 days a year. This design includes ten chapters: 1.An outline of the mine field geology; 2.Bound

8、ary 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;

9、 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is the Review of Water Resouces Preservation in Shallow Seam Mining. It makes a fully discussion of water resouces preservation in shallow seam mining in Shen-dong mining area.Translation part is aboat
