6、 covers the county township, all of Chengxiang Township and Hou Ling, Shuangqiaoshan nine kilometet, part of the rural population. Chengjiao Mine is to north F14 fault as a boundary, South of the artificial division. mines east-west length of about 5.06 km, North-south tilt width of 3。98 km, an area
7、 of about 21.36km2. The minable coal seam is 2# coal with an average thickness of 7.13m and an average dip of 8.3. The proved reserves of this coal mine are 212.77 Mt and the minable reserves are 142.14 Mt, with a mine life of 67.69 years. Mine the maximum discharge is 500m3/h, the normal discharge
8、is 400 m3/h; coal to anthracite; all mine gas emission in the absolute maximum for the 3.3 m3/min. Relative to the gas emission is 1.0 m3/t .a low-gas mines; The coal seams without coal dust explosion hazard. Each seam are not spontaneous combustion in coal seams.Mine uses shaft second the level of
9、development and uses Central parallel ventilation.Side of a mine ，mining technology is comprehensive mechanization Caving. The main transportation uses the adhesive tape transportation opporteunity coal. Auxiliary transport uses battery Locomotive traction tramcar. Mine is working days for 330 days,
10、 the net every day to enhance the time 16 hours. Mine system is 46 structure. Special subject part is about“Deep Roadway deformation mechanism and support technology”.the original English text of the title: Risk assessment of oor water inrush in coal mines based on secondary fuzzy.
