5、located in Pei County, Jiangsu Province, and Shandong Province, in Peixian 4 km north of the city, located in the southernmost tip of the Datun mining, the whole cover up the District. South and Pei Pei City mine, North and xuzhuang, mine adjacent to the East and Zaozhuang Bureau of Mines bordering.

6、The West play a Xupei Railway, east of the original Lau Sin Chong fault location, the South is bounded on the No. 21 coal seam outcrops, north to the coal seam 7 -1000 m horizontal and vertical projection. Ida east-west 5.38 km north-south width of 3.18 km, an area of about 17.13 km2.The mining area

7、 traffic is convenient. Self-Pei (Tuen Mun), Xu (State) special railway line to the Bluff Station Longhai line standards up across the country; regional highways, South Peixian to Xuzhou City, North via the Yutai to Jining City and east to Shandong vine state, Zaozhuang City; Ida eastern Beijing-Han

8、gzhou Grand Canal are available for the 100-ton ship sailed. Ida within each coal seam gas content is low, the case of low gas mine; coal seam has a certain risk of spontaneous combustion, natural preference rating of grade and coal dust explosion hazard.There was two-level, one level up the mountai

9、n, two levels down the mountain to open up, the use of central side-by-side ventilation. One side of the mine, the mining method Longwall mining, mining all high exploitation. Coal transportation using a flame-retardant tape and hoppers, tub, and auxiliary transport battery electric locomotive tract
