5、ing method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.Chengjiao coal mine lies in Yongcheng, Henan province. The boundary of the mine field runs 5.36km from north to south and 6.86km from west to east on average. T

6、he total plane area of the mine is about 37km2. There is only one exploring layer-number two. Its average thickness of the seam is 4.25m and its stable and flatly inclined. Its dip angle is 6 degree on average. The industry reserves of the mine field are 405.74 million tons and the useable reserves

7、are 285.91 million tons. The service life is 85.1 years. The average inflow rate in Chengjiao mine is 180 m3/h. It is a lower gassy mine. The coal dust doesnt have explosion hazard as well as the self-combustion tendency.This mine adopts vertical shaft development with two mining level (the first de

8、velopment level is located at the -580m, and the second is at the level of -750m.)and exhaust ventilation, centralized juxtapose earlier and radial later. The adopted coal winning method is the comprehensive mechanized longwall caving method along the dip with top-coal caving. The belt conveyor is a

9、pplied to transport coal. We work 330 days per year ,and exaltate 16 hours one day .The “threeeight” working system is applied for coal mining. The monographic study is supporting technology and analysis in the caving laneway.The translated academic paper is about imporvement of mining safety. Its t
