4、er.The general design is about a 2.4 Mt/a new underground mine design of Zhangshuanglou coal mine. It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system, designed mine capacity and mine life; 4.developmen

5、t of mining field; 5.preparation in strip district; 6.coal mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.Zhangshuanglou coal mine lies in Xuzhou, Jiangsu province.It is in Anguo town, the traffic is very

6、 convenient. Its about7.6 km on the strike and 2.7 km on the dip,with the 20.52 km2 total horizontal area. The minable coal seam of this mine is only 7 with an average thickness of 9.5 m and an average dip of 18. The proved reserves of this coal mine are 305.07 Mt and the minable reserves are 217.5

7、Mt, with a mine life of 64.73 years.The geological condition of the mine is relatively simple. The absolute mine gas is 3.73m3/min,and the absolute carbon dioxide is 26.21 m3/min .The maximum and minimum coal dust density and average is 337.8 mg/m3，136.8 mg/m3；35.4 mg/m3，16.2 mg/m3.The normal mine i

8、nflow is120 m3/h and the maximum mine inflow is 142 m3/h. It is bituminous coal with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal seam liable to dust explosion.This mine adopts vertical shaft development with two mining level and exhaust ventilation, centralize

9、d juxtapose earlier and radial later. The adopted coal winning method is longwall mining on the dip with top-coal caving. The belt conveyor is applied to transport coal and motor vehicles is used in the auxiliary conveying. We work 330 days per year ,and exaltate 16 hours one day .The “threeeight” w

10、orking system is applied for coal mining . The monographic study is the study of aquifer protective mining in shallow coal seam. The translated academic paper is about water inrushes .Its title is that Investigations of water inrushes from aquifers under coal seams.Keywords：the design of mine; top-c
