Zhuji coal mine is located in Huainan, Anhui province. It’s about 7.0 km on the strike and 3.0 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 11-2# with an average thickness of 1.32 m. And the average dip of the coal seam is 2.5°. The proved reserves of this coal mine are 144.83 Mtandthe , minable reserves are 118.03 Mtandthe, with a mine life of 75.66 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 and blind incline shaft two-level development method, and full strip preparation ,which divided into four bandsands , one district, and track roadway, belt conveyor roadway and return airway are all rock roadways, arranged in the floor rock of the two coal seams. Taking into account of the high gas emission, mine ventilation method use combined ventilation ventilation, and excaves bottom gas drainage roadway before mining to relief gas pressure inadvance.The design applies strip preparation against the first band of North One which divided into 6 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 2.5°, 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 drumshearer cutting coal which cuts twice each working cycle. “Three-Eight“ working system has been used in this design and the depth-web is 0.6 m with five working cycles perday,and the advance of a wor king cycle is 3.0 m and the advance is 90 m permonth.Main roadway makes use of belt conveyor to transport coal resource, and battery locomotive to be assistant transport. The main shaft uses double 16t s kips to lift coal with a balance hammerand. The auxiliary shaft uses a twins narrow 1.5t four-car double-deckcage and a wide 1.5t four-car double-deckcage to lift material and personnel transportation.The monographic study entitled “Application of technology about ‘Y’ type ventilation with roadway along goaf in Zhuji coal mine “, the study took 1111(1) bottom gas drainage Roadway of Zhuji mine as an example, conducted a detailed collection and processing to gas observation data, this paper presents the gas distribution and migration rule in a high gas mine, which had significant guidance for practical mine production.The title of the translated academic paper is “Underground lighting in coal mines“.Keywords: Zhuji coal mine; vertical shaft development; band mode; The full mechanized coal mining; driving roadwayalong goaf; “Y”type
