Datong queshan county kiln coal Co., Ltd. is located in a small Datong Beijing Zuoyun County Township Mao Guan Tun Cun dong. Ida Gata is an irregular polygon, 4.336km long from east to west, north-south width of 2.250km, Ida area 8.8106km2. Mining depth: from 1273.19m to 1185.19m. The main mining seam in No. 22 coal, the average thickness of 10.49m. The more simple geological conditions. Mine industrial reserves of 176970000 t. Mine gas emission rate is low gas mine. Mine inclined shaft development, mine ventilation for the parallel-type ventilation. Mine by longwall mechanized longwall top coal caving mining method. Working for the mine 330D, every time 18h net promotion. The system of mine use four six system, class three, class preparation production.
