Tianchen coal mine lies in Tenggzhou, Shandong province. , the traffic is very convenient. It’s about 7.1 km on the strike and 3.7 km on the dip,with the 26.00km2 total horizontal area. The minable coal seam of this mine is only 3 上 with an average thickness of 4.0 m and an average dip of 10°. The proved reserves of this coal mine are 137.13 Mt and the minable reserves are 104.37 Mt, with a mine life of 65.4 a.The geological condition of the mine is relatively simple. The normal mine inflow is 393 m3/h and the maximum mine inflow is 620 m3/h. It is bituminous coal 45 with low mine gas emission rate and coal spontaneous combustion tendency, and it’s a coal seam liable to explosion.Based on the geological condition of the mine, I bring forward four available project in technology. The first is vertical shaft development with two mining levels and the extension of inclined shaft go to -700 m; thr second is vertical shaft development with two mining levels and the extension of vertical shaft go to -700 m; the third is vertical shaft development with two mining levels and the extension of inclined shaft go to -820 m; the last is vertical shaft development with two mining levels and the extension of vertical shaft go to -820 m. The secend project is the best comparing with other three project in technology and economy. The first level is at -450 m, The second level is at -700 m, Because a major fault lies in the center of mine field, the mine field is divided into the north section and the south section..Designed first mining district makes use of the method of preparation in mining area, the length of working face is 223 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The working system is “three-eight”,with two teams mining, and the other overhauling. Every mining team makes three working cycle, with six working cycle everyday. Advance of working cycle is 0.6 m, and quantity of 5432.16 ton coal is makedeveryday.Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. Main shaft makes use of skip to transport coal resource, when subsidiary shaft makes use of cage to be assistant transport. In the prophase of mining the mine makes use of centralized ventilation method,when in the evening of mining the mine makes use of areas ventilation method. At the easy time of mine ventilation, the total air quantity is 6056.6 m3 per minute, the total mine ventilation resistance is 1322 Pa, the coefficient of resistance is 0.100N·s2/m8, equivalent orifice is 3.15 m2. At the difficult time of mine ventilation, the total air quantity is6536.4 about m3 per minute, the total mine ventilation resistance is 1779.1 Pa, the coefficient of resistance is 0.159 N·s2/m8, equivalent orifice is 2.87 m2. The cost of the designed mine is 110 yuan per ton.3The monographic study is Rock-burst and its prevention and control measures..The translated academic paper is about Optimization of soft rock engineering with particular reference to coal mining.Keywords:shaft; up-dip and down-dip minging; large mining height; single thunnel drivage; centralized juxtapose ventilation.4目 录一般部分1 矿区概述及井田地质特征
