1、本科生毕业设计姓 名： 学 号： 学 院： 应 用 技 术 学 院 专 业： 安 全 工 程 专 业 设计题目： 阳煤集团寺家庄矿400万吨井型设计 专 题： 高瓦斯掘进面瓦斯动力现象理论与研究 指导教师： 职 称： 讲 师 2009 年 6 月 徐州摘 要本设计包括三个部分，即矿井新井设计部分，专题部分和翻译部分。一般部分是阳煤集团寺家庄400万吨井型设计。其内容主要有：1矿区概述及井田地质特征：寺家庄矿位于昔阳县境内，地理位置优越，交通便利，本井田基本呈一单斜构造，构造复杂程度中等。井田走向为西北，向西南倾斜，地层比较平缓，倾角一般为510。本井田内共含煤18层，自上而下可采及局部可采煤层
2、有6、81、84、9及15号煤层，总厚度达9.9m。其中15号煤全区稳定可采，为主要可采煤层，也是首采煤层，最大厚度7.65m，平均厚度5.8m，本次设计主要考虑15号煤层。2井田开拓：全井田南北走向长17.316.5km，东西倾斜宽69km，井田面积约123km2。全矿井设计可采储量为 572.78Mt，其中15号煤不经济可采储量为173.33Mt，15号煤设计可采储量为408.27Mt，为首采煤层。本设计的矿井为大型矿井，开拓方式为主斜副立开拓，按4.0Mt/a的设计生产能力计算，15号煤服务年限为73a。3采煤方法及采区巷道布置设计：采用采区开采，设计工作面采用走向长壁采煤法，采用放顶煤
3、综采工艺。回采巷道的布置方式为一进两回一高抽四条巷道（一条进风巷，一条回风巷，一条内错尾巷，一条高抽巷）。采煤工作面长200米，采煤机每班割4刀，完成4个循环，每天则完成8个循环，每个循环进尺0.6m，则日推进度为4.8m，年推进度1440m，设计工作面采用三八制工作。4. 矿井通风设计：根据矿井的开拓开采的条件，矿井开采中央、南一和北一采区时采用中央并列式抽出式通风，矿井开采其余六个采区时，随着通风线路加长，中央并列式通风系统不能满足要求，采取分区式通风系统。矿井的风量分配由内向外计算，工作面采用“U+L”型通风，掘进工作面采用局扇进行压入式通风，根据矿井通风容易和困难时期的阻力选择主扇，矿
4、井利用反风道反风。5矿井安全技术措施：关于火灾事故预防及处理计划的编制。专题部分：题目为工作面的瓦斯防治技术现状及存在问题分析。其主要内容有：论述了综采工作面采空区瓦斯运移规律及其特点，分析了采区瓦斯涌出规律等，介绍了瓦斯抽放系统，并将其应用到实践中去解决煤矿安全生产的实际问题，取得了一定的效果。翻译部分：综采放顶煤瓦斯涌出的特点及防治摘要：通过对综放工作面瓦斯涌出特点的分析，提出了综合治理瓦斯的方法，以确保安全生产。关键词：瓦斯涌出；综放开采；煤矿安全全套CAD图纸，联系153893706AbstractThis design including three parts, namely mi
