【正文】 Abstract This design mine is opened by the Zhangxin coal mine new mine design for Jixi Mining industry group, This mine altogether has 4 level that can adopt coal seam， which is 7, 6C, 6B, 3, The total thickness of coal seam is M. The whole area strike long 5900 M, dip long 2150M, the area is square coal seam industry quality is 1/3 of coking coal, design well field recover resources , the design length of service is years. This design mine uses the double vertical shaft development,div ided as two mining levels, altogether 18 districts, biplane wing mining, two working face reach to produce, 7, 3 single layer mining, 6C、 6B consociation gathering main roadway uses 10 ton wire laying type electric lootive hauling, 3 ton dropbottom mine car transportation, the mining coal method is longwall coal mining method, the mining coal craft is the full mechanized mining roof processing method is all cross falls the law.
