6、ators.The general design is about a 4.0 Mt/a new underground mine design of Yaoqiao coal mine. Yaoqiao coal mine is located in xuzhou, jiangsu province. Its about 9.08km on the strike and 4.08 km on the dip, with the 37.05 km2 total horizontal area. The minable coal seam is 7# with an average thickn
7、ess of 8.5 m and an average dip of 11. The proved reserves of this coal mine are 502.43 Mt and the minable reserves are 358.20 Mt, with a mine life of 64.0a. The normal mine inflow is 325 m3/h and the maximum mine inflow is 465 m3/h. gas relative emission in far less than 10 m3 / t, is a low-gas coa
8、l mine.According to Ida geological conditions, the design uses a vertical shaft two horizontal development, the second level of the dark inclined shaft extension, Ida mining area up the mountain-layout is divided into five mining area ,two mining areas, track roadway, transportation roadway are rock
9、roadway layout in the coal seam floor strata. The mine for the low gas mine, mine ventilation mode with a central parallel ventilation.Using the mining area to prepare the way for East Third District was divided into 16 mining face, and coal, ventilation, material transport, to discharge refuse, pow
10、er supply system design.The design conducted coal mining technology design against the 7301 face. The coal seam average thickness of this working face is 8.5 m and the average dip is 11, the immediate roof is mud stone and the main roof is sand stone. The working face applies fully mechanized longwa
