中煤集团安家岭煤矿9号煤层开采设计.docx

1、摘 要大学时间的学习，让我掌握了较多的专业知识，能过这次毕业设计和毕业答辩，更让我了解到了理论与实际的差距，同时也感受到了自己在专业课方面的一些不足之处。本设计为平朔煤炭工业公司安家岭9#煤层设计，根据毕业实习时在安家岭一号井所收集来的地质条件，以及指导教师所分的课题方向，本设计主要是9#煤层的设计，其中包括了井田开拓、带区设计、采煤工艺、通风安全等方面的设计。本矿井倾斜长度约为 30.8 km，走向长约为36.5 km，9号煤层的厚度为12.91 m。9 煤倾角为 6。本井田内可采储量为 843.75 Mt，服务年限为130a。煤的工业牌号为气煤。本设计采用主斜副立回风立井单水平集中综合开拓

2、， 大巷采用带宽为 1600mm 的胶带输送机运输。由于副立井使用了特制的特大罐笼，辅助运输采用先进的无轨胶轮车运输。采煤方法为倾向长壁采煤法，采煤工艺为综合机械化放顶煤开采，采空区处理方法为全部垮落法。本设计通过多方案比较和综合技术比较以及相应的经济比较优化设计，其中开拓方案的比较，以大量的经济数据来核算，以便使设计更加合理。同时在设计过程中，结合了矿井的地质情况、煤层的受力等情况以及国内外的先进经验对倾斜长壁综放面倾斜长度及走向长度的合理确定进行了理论分析，这样使建成的矿井更加与实际相符。通过本次毕业设计，使我学到更多的采矿专业知识，加深了我对所学专业知识的理解和认识。更重要的是，通过做毕

3、业设计也培养了我们个人在实践中发现问题、分析问题和解决问题的真实能力,培养我们实事求是的科学态度和严谨的工作作风，为将来在工作岗位上更好的发挥自己的能力奠定了坚实的基础。由于本人所学到的知识有限，所以在设计中难免出现些错误，希望各位老师、同学们给予批评指正。关键词:9#煤层；储量；井田开拓；巷道布置；采煤方法；通风；运输。ABSTRACTThe study of college time, let me master more professional knowledge, can pass this graduation design and graduation defense, let

4、me understand the gap between theory and practice, but also feel some shortcomings in professional courses. This design is designed for Anjialing 9# coal seam of Pingshuo Coal Industry Company. According to the geological conditions collected in Anjialing No. 1 well at the time of graduation practic

5、e, and the direction of the project to guide teachers, this design is mainly the design of 9# coal seam. Including mine development, zone design, coal mining technology, ventilation and safety design. The inclined length of the mine is about 3.85 km and the strike is long. The thickness of coal seam

6、 No. 9 is 12.91 m.9 and the dip angle is 6 . The recoverable reserves in the mine are 843.75 Mt and the service life is 130 years. The industrial grade of coal is gas coal. This design adopts the single level integrated development of the main inclined and auxiliary vertical shaft and the belt conve

7、yer with bandwidth of 1600mm in the roadway. Because the auxiliary shaft uses special large cage, the auxiliary transportation adopts advanced trackless rubber wheel car. The mining method is inclined longwall coal mining, the coal mining technology is comprehensive mechanized caving coal mining, an

8、d the Goaf treatment method is all collapse. Law.The design is based on multi-scheme comparison, comprehensive technical comparison and corresponding economic comparison optimization design, in which the comparison of development scheme is based on a large amount of economic data to make the design

9、more reasonable. At the same time, in the process of design, the rational determination of inclined length and strike length of inclined longwall fully mechanized caving face is theoretically analyzed by combining the geological conditions of coal mine, the stress of coal seam and the advanced exper

10、ience at home and abroad. This makes the completed mine more in line with the actual situation.Through this graduation project, I learned more mining professional knowledge, deepened my understanding and understanding of the professional knowledge. More importantly, through graduation design, we hav

11、e also cultivated our real ability to find problems, analyze and solve problems in practice, and cultivate our scientific attitude and rigorous work style of seeking truth from facts. For the future in the job better to play their own ability to lay a solid foundation.Because I have learned limited

12、knowledge, so there are inevitably some mistakes in the design, I hope you teachers, students to give criticism and correction.Key word: Wei 9# coal seam; reserves; mine field development; roadway arrangement; coal mining method; ventilation; transportation目 录第一章 矿山简介以及井田地质特征11.1井田概述11.1.1矿山简介11.1.2
