2、。井田地质条件较为简单。矿井工业储量为15091.18万t，可采储量为12193.82万t。矿井设计生产能力为1.8Mt/a。矿井服务年限52.11 a。矿井涌水量不大，正常涌水量为28 m3/h，最大涌水量为38 m3/h。矿井相对瓦斯涌出量为4.06 m3/t，属低瓦斯矿井。矿井煤尘有爆炸危险性，煤层不易自燃，自然发火等级为级。矿井采用立井单水平开拓。一矿一面，采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤，辅助运输采用矿车。矿井通风方式为中央并列式，采用抽出式通风。矿井年工作日为330 d，日净提升时间18h，工作制度为“四六制”。专题部分题目是沿空留巷围岩稳定机理与支护技术研究

3、。分析说明了沿空留巷的围岩变形特征及构成；沿空留巷的阶段性矿压特征，沿空留巷巷道布置方式及其保护形式。总结了沿空留巷的破坏形式以及支护的关键，并介绍了一些沿空留巷技术的工程应用。翻译部分是一篇关于治理预测长臂工作面瓦斯的全新软件系统在采矿工业中应用的论文，英文题目为A new methane control and prediction software suite for longwall mines关键词：立井开拓；带区；综放；无极绳绞车运输；中央并列式通风ABSTRACTThis design includes three parts: the general part, special

4、 subject part and translation part.The general part is a new design of NO.1.8 of Xinyuan mine. 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

5、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.Xinyuan mine locates at the Liyuan town，southwest of Qinxin county in Shanxi pr

6、ovince，17 km away from the center of the Qinxin county. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 5.56 km in the south and north direction while a width of 3.43 km in the east and west direction on average. The total area is Approximatel

7、y 18.75 km2. The main coal seam in the mine is only one, which is the 2# coal seam. The average angle is 5.94 degree, while the thickness is about 6.18 m. The minefield geological condition is simple.The proved reserves of the minefield are 150.9118million tons. The recoverable reserves are 121。9382

8、 million tons. The designed productive capacity is 1.8 million tons per year. The service life is 52.11 years. The normal flow of the mine is 28 m3 per hour and the max flow of the mine is 38 m3 per hour. The Relative gas discharge quantity is 4.06 m3 per ton. Thus it is Low gaseous mine. The coal d

9、ust of the mine has explosion hazard. But the coal seam is not easily spontaneous combustion. The level of spontaneous combustion is .The development of the mine is single level with a main vertical shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mec

10、hanization puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type is centralized juxtapose. The ventilation method is extraction.The working

11、 days in a year are 330. Everyday it takes 18 hours in lifting the coal. The working system in the mine is “four-six”.The title of the special subject part is “Study of the surrounding rock Stabilization mechanisms and support technology on the gob-side entry retaining ”. The article introduced gob
