The general part is a new design for Fangezhuang mine, the text is divided into 10 sections : Overview of mine and geological features, Mine realm and reserves, mine system design and production, min
3、e exploration, mining area roadway layout, mining method, Underground transport, upgrading mine, and mine ventilation and mine safety technology major economic indicators. The Fangezhuang coalfield locates in the city of Tangshan in Hebei Province. The average strike length of the coalfield is 5,200
4、 m. The inclination length of the coalfield is 2,400m with an area of 10.7 square kilometers. There are three coal seams in this coalfield, No.9coal seam, No.10 coal seam , No.12 coal seam. Their thickness are 5.12m、4.88m、6.5m and the total thickness is 16.5 meters. The average angle is 10 degrees,
5、belongs to gently inclined medium thickness seam. The industrial reserve is 394Mt, the workable reserve is 282Mt. The annual design production capacity of Fangezhuang mine is 3.0Mt/a and the service life is 70.26 years. It use shaft single level upward and downward development: the level elevation i
6、s-460m. The mine method is the inclined longwall comprehensive mechanization mining method.It make a fully mechanized coal face to meet the whole mine production, the coal face is 300m, the transport equipment in the main entry is transport of belt. The ventilation mode of this mine is two-wing mode
