Yuan Dian mine in west is bounded Yuan Dian fault; East to 32 coal-1000m level projection lines and 39467500 at warp; South from a willow ~ 5 ditch fault and 10 coal seam outcrop lines; North to 32 coal-1000 m level projection lines and block registration boundary. The length of the minefield is about 6.9 ~ 13.6km, north and south wide 1.2 ~ 3.4km, field with an area of about 37.22km2. The 8# and 10# is the main coal seam. And the 8# is above the 10# with a vertical distanceof about 80m. The dip angle of the coal is 5~15 degree and the average one is 10 degree. The average thickness of the coal is 3.5m in 8# and 3.6m in 10#.The proved recoverable reserves of the minefield are 214.47 million tons, and the minable reserves are 148.23 million tons. The designed productive capacity is 1.8 million tons per year, and the service life of the mine is 58.8 years. The normal flow of the mine is 392m3 per hour and the max flow of the mine is 584m3 per hour. The relative mine gas gush is 10.08m3/t, It is a high gas mine. The mine is a double level dark tilt extending depth and concentration rock roadway to develop and full strip preparation, which divided into three working areas and eight bandts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 10# coal seam.The design applies strip preparation against the first band of West Two which divided into 3 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 8201 face. The coal seam average thickness of this working face is 3.5m and the average dip is 15°. The “four-six” working system is used in the mine. It produces for 330 days a year. The working face applies fully mechanized longwall full-height coal caving method, and uses double drum shearer cutting coal which cuts twice each working cycle. The depth-web is 1.0m with six working cycles per day, and the advance of a working cycle is 6.0m and the advance is 165m per month.The central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is earlier stage which using boundary juxtapose form and later stage which using center juxtapose form. The main shaft uses double 16t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.0t four-car double-deck cage and a wide 1.0t four-car double-deck cage to lift material and personnel transportation.The topic of special subject parts is the restoration technology of large section and loose-fractured Instability roadway which in high seepage pressure.Translation part is about the useage of coal mine of US, and discusses to set up a mechanical anchor system to improve the performance of bolt. Its English title is “Improving Rockbolt Installations in US Coal Mines”.Keywords:Yuandian coal mine; Double vertical shaft; Panel layout; Center juxt aposesventilation; Large section roadway;
