2、均5。煤层平均厚度3#煤层3.5 m，15#煤7.5 m。井田地质条件较为简单。矿井工业储量为330.2297Mt，可采储量为220.6853Mt。矿井设计生产能力为3.0Mt/a。矿井服务年限61.3 a。矿井涌水量不大，正常涌水量为50 m3/h，最大涌水量为100 m3/h。15#煤相对瓦斯涌出量为4 m3/t，属低瓦斯煤层。矿井煤尘无爆炸危险性，煤层不易自燃，自然发火等级为级。矿井采用立井两水平开拓，上行开采。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，辅助运输前期采用1.5 t固定箱矿车，后期采用齿轨车运输。矿井通风方式前期为中央并列式，后期根据需要在井田东西两

3、翼增加两个边界风井。矿井年工作日为330 d，日净提升时间16 h，工作制度为“四六制”。专题部分题目是双巷掘进副巷采动变形规律的数值模拟研究。以阳煤集团新大地煤矿为例，通过使用UDEC数值模拟软件进行分析计算，模拟了15202工作面开采后，不同尺寸煤柱条件下进风副巷与进风巷之间煤柱的应力与变形的演化规律，以及不同尺寸条件下进风副巷的应力、变形的演化规律，得出双巷掘进时副巷受采动变形的基本规律以及煤柱尺寸的合理留设。翻译部分是一篇深部煤与瓦斯突出矿井危险等级的分类技术的论文，英文题目为Classification technique for danger classes of coal and

6、ation of the mine; 10.The basic economic and technical norms.No.3 of Yangquan mine locates at the west of Yangquan Mine area, 7.5 km away from the center of the town. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 7.6 km in the east and west

7、direction while a width of 3.0 km in the south and north direction on average. The total area is Approximately 21 km2. There are mainly two coal seams in the mine 3# and 15#. First mining15# seam upstream mining.The average angle is 5 degree, while the thickness is about 7.5 m. The minefield geologi

8、cal condition is simple.The proved reserves of the minefield are 330.22million tons. The recoverable reserves are 220.68 million tons. The designed productive capacity is 3.0 million tons per year. The service life is 61.3 years. The normal flow of the mine is 50 m3 per hour and the max flow of the

9、mine is 100 m3 per hour. The Relative gas discharge quantity is 4 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has non-explosion hazard. And the coal seam is hardly spontaneous combustion. The level of spontaneous combustion is .The development of the mine is double level with

10、two vertical shaft. The number of the working faces is only one. Comprehensive mechanization 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 ventilati

11、on type in the early stage is centralized juxtapose. In the late stage two air shafts in the boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “four-six”.The title of t
