SuanCiGou coal mine is located in Erdos City in the Inner Mongolia Autonomous Region Zhungeer Qi sand Ge blocks east27km, mine is located in the middle part of Zhungeer coalfield, the length , eastwest width of ~ , an area of about45km2. The main coal seam of 4,5,6 and6coal mine geological conditions, simple. Mine industrial reserves . Normal mine discharge is 276 m179。/ h,400 m179。/ h maximum gushing water. Mine gas emission low, low gas mine. Mine ventilation for the central parade, ventilation method for extraction type, main, auxiliary air inlet, air ventilation shaft. There is only one level of the mine, mine using prehensive mechanized caving coal mining method. Using belt conveyor coal, auxiliary transport using trackless rubber tire vehicle transport. Mine year work on330d, time 16h every day promotion. Mine working system with three eight, two zero four hour, four hours maintenance.
