4、 general design is about a 1.5Mt/a new underground mine design of Xiandewang 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.development of mining

5、 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.Xiandewang coal mine lies in Xingtai,Hebei province. The traffic is very convenient. Its about 3.407 km on th

6、e strike and 4.463km on the dip,with the 15.21km2 total horizontal area. The minable coal seam of this mine is only 2 with an average thickness of 3.72m and an average dip of 8. The proved reserves of this coal mine are 160.58 Mt and the minable reserves are 123.11Mt, with a mine life of 61.23 a. Th

7、e geological condition of the mine is relatively simple. The absolute mine gas is 2.42m3/min,and the absolute carbon dioxide is 8.23 m3/min .The maximum and minimum coal dust density and average is 137.8 mg/m3，86.8mg/m3；102 mg/m3，16.2 mg/m3. It is bituminous coal with low mine gas emission rate and

8、coal unspontaneous combustion tendency, and its a coal seam unliable to dust explosion,according to the research made by the branch of CCRI in Chongqing.This mine adopts vertical shaft development with single mining level and exhaust ventilation, centralized juxtapose earlier and radial later. The a

9、dopted coal winning method is longwall mining with fully mecharized mining technology. The belt conveyor is applied to transport coal and motor vehicles are used in the auxiliary conveying. We work 330 days per year, and exaltate 16 hours one day .The “threeeight” working system is applied for coal

10、mining. The monographic study is about technologies of roadway in deep mine fields. The translated academic paper is about tcoal mining environment post assessment .Its title is that the research on coal mining environment post assessmen.Keywords：the design of mine;fully meacharized technology; cent
