The whole article is dividedof Chengjiao Mine in Yongcheng coal & electricityo ten parts: the outline of the mine, the mine fieldgeology, the boundary and reserves, th

4、e designed productive capacity, the service life andworking area, the coal transporion, the mine lifting, theventilation and safety, and the maineconomical and technological index of the mine.The Chengjiao Mine fields in Yongcheng in Henan province. The boundary of the minefield runs 8km from north

5、to sound 11km from west to east oage. The total plane areaof the mine is about 90km2. There is only one exploring layer-number two. Its average thicknessof the seam is 4.5m and its stable and fly inclined. Its dip angle is 6.18 degree oage.The industry reserves of the mine field are488 million tons

6、and the useable reserves are395million tons. The average inflow rate in Chengjiao mine is 180250 m3/h. It is a lower gassymine. The coal dust doesnve explohazard as well as thebustion tendency.The productive capacity of Chengjiao Mine is 3.0 million tons per year，and the service lifeis 90 years. The
