Based on a series of technique and economy comparisons, the suitable mine development scheme,mining method, mine’s (working area’s) openings and each main production system have been determined． The geologic structure in the coalield is simple,the main structure is Caogou Anticline acrossed the field from south to north． The mine has high gas and danger of coal-dust explosion. The designed main coal seams have two layers, including 3# coal seam and 4# coal seam from shallow to deep. Their average thickness is 2.77m and 3.32m respectively. Their angle of dip is 5o～9o, the average is 6o, so they belong to flat seams.The designed capacity of the mine is 4 million t/a and the expected life of the mine is 76.6 years. Based on technique and economy comprisions, the design chooses vertical shaft development for the first level, adopts long wall mining method along the dip and comprehensive mechanized coal mining. The auxiliary haulage system is separated from the mai
