6、and Hongdong goes through the north of well field; it wides 17km to the east and reaches two highways, one between Fenyang and Tunliu, the other between Qinyuan and Qinxian in Qinyuan County. The distance between this mine and Qinxian railway station, a station on the railway between Taiyuan and Jia
7、ozuo, is 76km ; 54km from this mine to Zhangdian Town on 309 Road ; 100km to Xiujie City; 105km to Pingyao County; to the southwest after 75km it reaches the highway between Datong and Yuncheng and the south Tongpuhongdong railway station, so the transportation is convenient. The average strike leng
8、th is 5.82 km. The average tilt width is 3.98 km. The average angle is 5.4 degrees. The horizontal width of field well is 1km. The horizontal area is 17.88 square kilometers. The maximum gushing water of mine is 120m3/, the normal discharge is 60 m3/; the coal is coking coal mine; the maximum absolu
9、te gas emission quantity is 7.5 m3/min, which belongs to low gas mine; coal seam is not spontaneous combustion coal, which has the explosion risk.Mine uses double Shaft single the level of development, alongside the use of the central ventilation. Side of a mine, mining method for a fully mechanized
10、 longwall mining height. The use of flame-retardant tape transport of coal to support the use of non-class transport winch rope.Mine is working days for 330 days, the net every day to enhance the time 16 hours. Mine system is 46 structure.Special subject part is about large mining ore fully mechaniz
