This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield; 5.The layout of mining area; 6.The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Caocun coal mine lies in northern part of Linfen, Shanxiprovince,about 7km to southeast of Huozhou. It’s eastern longitude is 111°44’~111°48’,north latitude is36°31’~36°33’.There is a railway siding in the Caocun mine field,about 4.5km in length,the traffic is very convenient. It’s about 1.1~4.4 km on the strike and 2.5~3.5 km on the dip,with the 12.17 km2 total horizontal area. The minable coal seam of this mine arefour parts,including 2, 9,10,11,with an average thickness of 4.0 m and an average dip of 8.3°. The proved reserves of this coal mine are 248.42 Mt and the minable reserves are 163.40 Mt, with a mine life of 69.83a.The geological condition of the mine is relatively simple. The normal mine inflow is 400 m3/h and the maximum mine inflow is 482 m3/h. Itis coke coal with low mine gas emission rate and none 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 projects in technology. The first is vertical shaft development with two mining levels and the extensionof vertical shaft go to 340m and 200m,the main tunnels are developed in the coal seam; thr second is vertical shaft development with two mining levels and the extensionofinclined shaft go to 340m and 200m, the main tunnels are developed in the coal seam; the third is vertical shaft development with two mining levels and the extensionof vertical shaft go to 340m and 200m,the main tunnels are developed in the rock stratum; the last is vertical shaft development with two mining levels and the extensionofinclined shaft go to 340m and 200m,the main tunnels are developed in the rock stratum. The first project is the best comparing with other three projects in technology and economy.The first level is at 320 m, The second level is at 200 m,themine field is divided into the north section and the south section, the south section is one level service scope, and the north section is two level service scope.Designed first mining district makes use of the method of preparation in mining area, the length of working face is 160 m, which uses caving mining technology, and fully caving method to deal with goaf. The working system is “three-eight”,with two and a half teams mining, and the other overhauling. Every mining team makes two working cycle, with five working cycleseveryday. Advance of working cycle is 0.8 m, and quantity of 5788.8 tons 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 ofcentralized ventilationmethod,when in the evening of mining the mine makes use ofareasventilation method. At the easy time of mine ventilation, the total air quantity is 5842.2 m3 per minute, the total mine ventilation resistance is 1027.8 Pa, the coefficient of resistance is 0.351 N·s2/m8, equivalent orifice is 2.01 m2,mine ventilation is easy. At the difficult time of mine ventilation, the total air quantity is about 46598.2 m3 per minute, the total mine ventilation resistance is 2239.5 Pa, the coefficient of resistance is 0.620 N·s2/m8, equivalent orifice is 1.751 m2,mine ventilation is hard. The special subjectis about Caocun village of coal mine floor high pressure water conditions and bottom aquifer outstanding analysis water exploration technology.The translated academic paper is aboutResearch on Coal Mine Safety Evaluation SystemBased on Risk Management,english subject is Research on Coal Mine Safety Evaluation SystemBased on Risk Management.Keywords:shaft;working filed;two extracting levels;up-dip and down-dip minging;caving mining;double tunnel drivage;centralized juxtapose ventilation.目 录一般部分1 矿区概述及井田地质特征 ..............................................................................11.1 矿区概述 .....................................................................................................................11.1.1 矿区地理位置 .......................................................................................................11.1.2 矿区气候条件 .......................................................................................................11.1.3 矿区地貌、水文情况 ...........................................................................................21.1.4 矿区地震 ...............................................................................................................21.2 井田地质特征 ..............................................................................................................21.2.1 以往地质报告及勘探工作简况 ...........................................................................21.2.2 煤系地层 ...............................................................................................................21.2.3 井田地质构造 .......................................................................................................41.2.4 水文地质特征 .......................................................................................................51.3 煤层特征 ......................................................................................................................81.3.1 可采煤层 ...............................................................................................................81.3.2 煤的特征 ...............................................................................................................91.3.3 其它有益矿产 .....................................................................................................111.3.4 瓦斯、煤尘及自燃 .............................................................................................122 井田境界与储量 .........................................................................................132.1 井田境界 ....................................................................................................................132.1.1 井田范围 .............................................................................................................132.1.2 开采界限 .............................................................................................................132.1.3 井田尺寸 .............................................................................................................132.2 井田地质勘探 ............................................................................................................132.2.1 勘探类型 .............................................................................................................132.2.2 钻孔分布及储量等级圈定 .................................................................................132.2.3 最小可采厚度 .....................................................................................................142.3 矿井地质储量 ............................................................................................................142.3.1 储量计算基础 .....................................................................................................142.3.2 矿井地质储量计算 .............................................................................................152.3.3 矿井工业储量计算 .............................................................................................162.4 矿井可采储量 ............................................................................................................162.4.2 工业广场保护煤柱 .............................................................................................162.4.3 风井保护煤柱 .....................................................................................................182.4.4 大巷保护煤柱 .....................................................................................................182.4.5 矿井可采储量 .....................................................................................................183 矿井工作制度、设计生产能力及服务年限 ......................................................20
