(完整版)安全工程本科毕业设计

1、太原理工大学太原理工大学继续教育学院毕业设计（论文）纸太原理工大学毕业设计说明书毕业生姓名：专业：学号:指导教师:所属系（部）二O五年十月毕业设计是采矿工程专业最后一个教学环节，其目的是使本专业学生运用大学阶段所学的知识联系矿井生产实际进行矿井开采设计，并就本专业范围的某一课题进行较深入的研究。以培养和提高学生分析和解决实际问题的能力，是学生走上工作岗位前进行的一次综合性能力训练，也是对一个采矿工程技术人员的基本训练。本次设计的内容是麦地掌煤矿通风系统设计。是在麦地掌煤矿井田概况和地质特征的基础上，结合搜集到的其它相关原始资料、运用所学知识、参考煤矿开采学、煤炭工业矿井设计规范、煤矿矿井开采设

2、计手册等参考资料，在辅导老师深入浅出的精心指导下独立完成。在设计的过程中我受益非浅。此次毕业设计是根据国家煤炭建设的有关方针、政策，结合设计矿井的实际情况，遵照采矿专业毕业设计大纲的要求，在收集、整理、查阅大量资料的前提下，运用自己所学的专业知识独立完成设计的。通过本次设计，我看到了许多以往自己欠缺的地方，提高了综合能力，知识水平有了很大的提高，由于本人的初次设计，错误难免，恳请各位老师指正。本次设计的指导老师为老师，同时还得到了田取珍、曲民强、丰建荣、王开等老师的悉心指导，他们在许多方面给予了宝贵意见，为了帮助我们顺利、正确地完成毕业设计，经常加班加点，牺牲了大量的工作时间和业余时间，在此表

3、示衷心的感谢和深深的敬意！由于本人水平有限，设计中难免存在错误和不足，恳请各位老师不吝指正。学生太原理工大学太原理工大学继续教育学院毕业设计（论文）纸太原理工大学太原理工大学继续教育学院毕业设计（论文）纸 外文资料Worldcoalminingtechnology1undergroundmining1outlinedCurrently,undergroundminingisthemainhardcoalminingmethods.China,theformerSovietUnion,theEuropeanintroductionofthelongwallcoalmininglaw,theUni
