前言
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。

摘要
本次设计是开采麦地掌煤矿02、6、8#煤层，煤层厚度分别为 3.3m、1.86m、2.14m，煤层间距分别为60m、40m。据井田外围资料调查该井田为高瓦斯矿井，上组煤瓦斯涌出量平均为14.24m3/t，下组煤为35.22 m3/t。煤层均有爆炸危险性。煤的自然倾向等级为不易自燃。根据矿井涌水量预测，该矿井正常涌水量为1255m3/d，涌水量最大时为1600 m3/d。
本井田位于清徐县城北约10km处，其间有清徐～古交公路相通。清徐县城距太原市约40km,其间有307国道相通。井田内地形虽较复杂，但村与村之间均有简易公路相联，可通行卡车。所以工业广场的位置位于陈家坪附近，采用立井开拓，主、副立井及风井的断面分别为33.2m2、19.625 m2、19.625 m2。开拓方案一为从陈家平附近向北开掘东运输、轨道、回风大巷至北部井田边界，然后再从陈家坪向西开拓南运输、轨道大巷，再向北掘进西运输、轨道、回风大巷。方案二是在陈家坪的南侧掘进运输、轨道和回风大巷，然后在井田西侧掘进西运输、轨道、回风大巷至北部边界。方案一、二的工业广场都位于陈家坪附近。根据比较开拓工程量可视为相同，但在技术上方案二出现反向运输，且工作面推进方向太长，设备要求高，所以选择开拓方案一。开拓方案一划分为四个盘区，整个井田划分为38个条带，首采区定为中央一盘区，盘区储量为20.4Mt 。
矿井达产时的首采工作面位于一号盘区，该盘区划分为11个条带，工作面长度为180m，推进长度为1950m，回采工艺采用后退式、综采一次性采全高机械化采煤法，采用“三八制”作业制度。采空区采用全部跨落法管理顶板。
矿井通风采用抽出式通风，矿井总风量为102m3/s困难时期和容易时期的风阻分别为1277P a、2413 P a。通风机的型号为FBCDZ-10-NO30D，其风量范围为54-184m3/s,风压范围为1200-3690 P a。
Abstract
The design is the exploitation of MaiDiZhang 02,6,8 # coal mine, coal seam thickness was 3.3 m, 1.86m, 2.14m, seam pitch was 60 m, 40m. According to data mine the external investigation of the mine field for the high-gas coal mine, the coal gas emission in an average of 14.24m3/ t, the next group of coal to 35.22m3 / t. Seam of both the risk of explosion. Grade coal to natural tendency not spontaneous combustion. According to mine discharge forecast, the normal discharge of mine for 1255m3/ d, Chung's largest water at 1600 m3/ d The Coal Mine in Qingxu county, 10 km NATO, which has Gujiao Qingxu to the same highway. Qingxu county from the Taiyuan city about 40 km, which has the same 307 National Road. Although the mine in more complex terrain, but between the village and village roads are linked to simple, can use trucks. Therefore, the location of Industry Square in the vicinity of Chen Jia Ping, a shaft development, Lord, vice shaft ventilation shaft and the section were 33.2 m2, 19.625 m2, 19.625 m2. Develop a programme for the Chen-ping from the vicinity of the north east is necessary to develop the transport, rail, air return roadway to the north mine the border and then west from Chen Jia Ping pioneering South transport, rail tunnel, and then north tunneling West transport, track , To the wind tunnel. Option 2 is in the south of Chen Jia Ping tunneling transport, rail and air return roadway, and then in mine excavation west of the West transport, rail, air return roadway to the northern border. Option 1, two are located in the industrial plaza near Chen Jia Ping. According to comparison can be regarded as pioneering works of the same, but the technical programme in the reverse transport, and face the direction of advancing too long, equipment requirements, so I chose to develop a programme. Develop a programme was divided into four zones, the entire mine field is divided into 38 bands, the first mining area as a central one, panel reserves of 20.4 Mt.
Mine production of the coal face in the first set on the 1st District, which was divided into 11 bands, face a length of 180 m, promote the length of 1950 m, using back-mining process, Fully-high one-time full-mechanized coal mining Law, the "March 8" operating system. Gob-of-use of all management roof.
Out of a ventilation shaft ventilation, the total air volume of mine for 102 m3/ s easy and difficult period during the Drag were 1277 Pa, 2413 Pa. Fans of the model FBCDZ-10-NO30D, its air volume range of 54-184 m3/ s, wind pressure range of 1200-3690 Pa. Key words: mine development, mining methods, fully mechanized coal mining.
