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
