Zhuji coal mine is located in Huainan, Anhui province. It’s about 7.0 km on the strike and 3.2 km on the dip, with the 21.0 km2 total horizontal area. The minable coal seam is 13-1# with an average thickness of 4.0 m and an average dip of 3°. The proved reserves of this coal mine are 113.12 Mt and the minable reserves are 53.09 Mt, with a mine life of 42.1 a. The normal mine inflow is 342 m3/h and the maximum mine inflow is 462 m3/h. The mine gas emission rate is 10.3 m3/t,which can be recognized as high gas mine.Based on the geological condition of the mine, this design uses a duel-vertical shaft single-level development method, and full strip preparation ,which divided into eight bands and two districts, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of 13-1# coal seam. Taking into account of the high gas emission, mine ventilation method use two diagonal wings ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure in advance.The design applies strip preparation against the first band of East One which divided into 5 stirps totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The design conducted coal mining technology design against the 13101 face. The coal seam average thickness of this working face is 4.0 m and the average dip is 3°, the immediate roof is mud stone and the main roof is sand stone. 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. “Three-Eight“ working system has been used in this design and the depth-web is 0.8 m with five working cycles per day, and the advance of a working cycle is 4.0 m and the advance is 120 m per month.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 16 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5 t four-car double-deck cage to lift material and personnel transportation.The project section on “the use of the trackless rubber_tyred car at home and abroad present situation and developing trend“, In combination with the application in ShenDong mining area, JiSan Mine, this paper introduces the performance characteristics of trackless rubber_tyred car, using situation, main models, and the localization process and the future development trend of trackless rubber_tyred car.The title of the translated academic paper is “ A new coal pillars design method in order to enhance safety of the retreat mining in room and pillars mines “. Mainly introduces a new type of room and pillar mining, can improve the safety of coal pillar coal pillar design method.Keywords:Zhuji coal mine; double vertical shaft; band mode; two diagonal wings
